The Commission, accordingly, exercises the same juris- diction in connection with the licensing of water power projects in the Territory of Alaska as it does in the several States. The Regional Forester at Juneau acts as the Alaska representative of the Commission. The natural relationship of water power and timber in the area has brought about coordination of the activities of the Federal Power Commission and of the Forest Service concerning appli- cations for any proposed development of these resources in Southeast Alaska. The timber in the Tongass National Forest is a large source of lumber, plywood, pulp and other forest products and the water powers in proximity to the forest possess valuable potentiality as a source of power for use in cropping the timber resources. Where forests and water power coincide geographically they com- plement each other in a natural economy of development. There are in Alaska at the present time about 50 water power projects involving more than 30,000 horsepower and ranging in size from 10 to 5,000 horsepower installations •. A few of these are under Forest Service priority, which was the manner of issuing permits prior to the passage of the Federal Water Power Act in 1920. Since 1920 the projects have been licensed under the Federal Water Power Act. Studies of potential water power sites of Alaska have been limited almost en- tirely to the Southeast. Power resources in other parts have not been surveyed, except to a limited extent in the South Central section where a study was undertaken in 1913 but discontinued after five months of field work. The power surveys summarized in the study contained in this volume on Southeast Alaska have more than a million average horsepower. Only about 10 percent of the total area of this region is included in the watersheds involved in these studies. Therefore, considerably more field work would be necessary to complete this file of general information. . The report indicates that it is possible to create dependable blocks of power by coordinating many of the power sites into an integrated utility system. There appear to be sites for communities not too far from the general concentration of power and natural transmission patterns •. Outstanding characteristics of the region are rather small drainage basins with heavy run-olfs, high heads with relatively short conduit lines leading to tidewater plants, good accessibility to navi- gable waters, and some natural storage facilities which lend themselves to seasonal and annual hold over. The run-off characteristics are such that both seasonal and annual storage capacity are essential to create blocks of dependable power necessary to meet energy requirements. Many natural lakes can be enlarged to create sufficient storage capacity for seasonal and annual hold over. There are indications that this storage can be utilized to firm the power of the river-run hydro plants in those streams where sufficient storage capacity is n()\ obtainable. Although the power sites of Southeast Alaska are relatively small in capacity, their total poten- tiality suggests the desirability of over-all development. There are 200 potential projects which it is estimated could develop 1,008,370 average horsepower. Of these, 27 range in size from 10,000 to 51,000 average horsepower each, or a total potential of. 534,530 average horsepower. In develop- ing a power system, many of these projects would logically be interconnected with high voltage transmission. The remaining projects and some of. less capacity, but susceptible to automatic control and operation, could be interconnected through the principal stations at lower voltage trans- mission. This would permit the advantages of economy to extend throughout the system and keep the installation cost at the optimum. The utilization of this power would depend upon the types of industries to be located in the area. The industries which might operate extensively are mining, milling, electrometallurgic processes, II FOREWORD pulp and paper production, forest products, and other similar manufacturing suitable to the region's resources. At present mining is the most important user of water power. Development of forest products might prove to be a real incentive for the development of water power resources in this area. It has been estimated that 250,000 horsepower would probably produce a million tons of news- print per year. The last previous report of this kind published by the Federal Power Commission was issued in 1924. It was familiarly known as the "Dort Report" on the "Water Powers of Southeastern Alaska". This study was made by J. C. Dort of the U. S. Forest Service. Dort's report covers 50 water power sites. The original data in this report were assembled and the field investigation was carried out by Mr. R. Robinson· Rowe, of the Forest Service stalf, Juneau, Alaska. Be viewed 47 of the power sites in the field, visiting shores scarcely touched by even a native and only occasionally observed by a pa~sing fisherman. While this volume is a joint undertaking and many persons have contributed valuable assistance in its compilation, generous credit is due to Mr. Rowe for his efforts in attempting to insert all essential details necessary for an engineer to form an opinion as to the potential power in each project. To point out how and where a dam, a conduit or a power house may be advantageously placed in this rugged topography is an art born of experience and a natural understanding of the terrain. His work in developing a chart, involving run-off and storage regulation, applicable to an area of such high precipitation, has made available a means of helping to determine an element vital to the feasibility of a project; it is especially useful where recorded data do 'not exist as so frequently is the case in this region. All of the factual data and statements appearing in the project reports involving applications or official data filed with the Federal Power Commission have been checked by the Commission's staff or the Forest Service stalf at Juneau as to their completeness and accuracy. The data in 114 applications are referred to in 91 of the described projects reported herein. Of these 114, 29 are priority applications made to the Forest Service before 1920. Whenever any general statement is made which is not based on a field report or other available official information, there has been an endeavor to make it clear that the data are estimates based upon theengineertng judgment of thefield staff. Such estimates were necessary for several reasons, such as an inadequate survey, no survey at all, merely an observation, or a verbal report from a prospector furnishing information as to waterfalls in the, area he explored; and either partially made or completed reports from consulting engineering firms employed by exploration and mining companies interested in potential development of timber or ores. In many cases firms directly interested in obtaining permits to cut the forests and at the same time use water power energy to accomplish the undertaking have supplied useful information. These reports have been made avail- able to the Forest Service and the Commission, and have been drawn on extensively for the data contained in them, but in each case where this is true there has been an attempt to make the refer- ence clear and to show that the facts so developed are dependent upon the source from which they are taken. Some of the information has been estimated from aerial photographs of areas heretofore practically unknown, by means of which many lakes have been discovered and watersheds deter- mined. While the Commission is making available to the public ir.. this report the best information which exists at present, it cannot assume responsibility for any inaccuracy which may be revealed as a result of further surveys and which may render some of the data obsolete. The work for the Federal Power Commission was done under the general supenisionof E. Rob- ert de Luccia, Chief, Bureau of Power. Dr. Fayette S. Warner has arranged and edited the report. He has materially added facts and figures of special interest and has also contributed the section dealing with coordination which is of vital importance in the construction of any utility system. WATER POWERS OF SOUTHEAST ALASKA III INTRODUCTION The water powers of Southeast Alaska are an undeveloped resource. The development of these water resources for power will provide the basic energy source for the industrial growth of the region. The purpose of this report is to bring to- gether the best data which can be assembled on water power and how it may be transmitted from generating sources to points of utilization. It has a definite bearing on the proper develop- ment and husbandry of the region's raw materi- als, at present lying dormant, which, when har- nessed, will become an active asset, and pro- duce an annual harvest of needed mate rials to flll an ever present demand. By this means a thrifty population may furnish needed products for others to consume. While the 40 million dollar salmon pack, sold fresh, frozen and pickled, furnishes expendable consumer goods for a wide market, the mineral and forest prod- ucts of the area will eventually supply a durable goods market. This study is especially con- cerned with water power, a basic element in the region's development, and a natural tool, so to speak, having a complementary part to perform in bringing about this economic improvement and the production of these durable goods which cannot be produced except through the utilization of energy. This volume contains many full length sketches . and thumbnail summaries of potential water power projects. Only the salient features are included in each description, with a few ex- ceptions where extended surveys have been completed in tbe field, or where a project has been actually installed. The prineipal features, in general, include the location, the lakes or possible storage places in the watershed to- gether with their size and drainage areas, and whether a trail to the site is constructed or blazed. The run-off in cubic feet per second is taken at selected points, such as at a probable dam site, diversion, or lake ouUet. Considera- tion is given to regulating the. stream flow, the · creation of storage capacity and its effect on bringing about a continuous discharge of the stream for power purposes. The dam sites, a description of the topography and geologic formations affecttnc the foundations, and the type of dam suitable to the location, together with its dimensions and the type of materials at hand for its construction are mentioned. The length of conduit, power plant location and the developed head are usually included. The power capacity is statedin primary and average horse- power, and as a combined total if more than one plant is involved in the project. Under remarks are included references to licenses, priorities, and local history, together with the description of any power plants and equipment if they have been installed. Occa- sionally various alternate plans of development are stated, and whether there is an opportunity to annex a nearby watershed advantageously. In support of these project data, are collected all of the water discharge records by months and years taken at some 50 stations for varying periods during which they were in oper~tion. The analysis of run-off from these records is included together with precipitation to de- termine such factors as the engineer might desire to apply to the streams on which no pre- vious discharge records exist. The capacity of storage needed for regulation, both complete and partial, is derived from the same general analysis. Descriptions of the geography, topography, geology and natural resources appear at the be- ginning of the volume. A general statement of climatic conditions supported with some data, and analyzed, indicate the effect of air masses moving in over the warm Pacific, which, be- coming saturated, precipitate this moisture on the mountainous terrain during all seasons of the year. The tides of the area are relatively high and have an effect on construction programs and the potential development of power, and there- fore must be taken into consideration whenever a project is planned. Because of this, a few paragraphs describing the various phenomena causing tides and their relative range are in- cluded in the report. HISTORICAL The mineral deposits, fisheries, wildlife and potential wealth of natural resources was scarce- ly thought of in 1887 when Alaska was purchased from Russia for $7,200,000. 'l'h& Alaska fish- ing and fur trapping industries have produced over a billion dollars worth of products, and the mines more than three-quarters of a billion during our ownership, which means a gross average return of over 300 per cent annually. Russia based her claim to the ownership of IV WATER POWERS OF SOUTHEAST ALASKA Alaska upon the early voyages of Vitus Bering, a Danish captain in the Russian Service, and his second in command, Alexi Cherikof, during the years 1728 to 1742. Tales brought back by early explorers of wealth in furs encouraged Russian exploration and colonization. The suc- cess of colonization can be traced to Alexander Baranof, manager of the Russian American Company until 1818, who exercised absolute dominion over Alaska for 67 years. Russia first attempted to sell Alaska to the United States in 1855 during the Crimean War, when it was feared that England would seize Russian America. A few years later the West- ern Union Telegraph Company negotiated for the joint construction of a telegraph llne from Europe to the United States by way of . Bering Strait~ Work was actually started in 1866, but the enterprise was never completed because of the successful laying of the Atlantic Cable by Cyrus Field. These activities greatly influenced opinion with regard to Alaska and it was finally pur - chased for about 2 cents an acre. The Ameri- can public generally was ignorant of the country at the time of its purchase, and the press re- ferred to Alaska as "Seward's Folly" and other less becoming names. From 1867 to 1884 an era of stqnation en- sued for Alaska, during which it was almost completely neglected. The United States Army was in charge for the first decade of our stew- ardship. Its jurisdiction was withdrawn from the Territory in 1877 and for two years follow- ing this there was no government of any des- cription. Trouble arose with the Indians over the liq- uor traffic and local residents were forced to appeal to the British Admiral at Victoria, Brit- ish Columbia, for assistance and protection when authorities in Washington ignored their pleas. Protection was later extended to Alaska and order was maintained by captains of the United States Navy until 1884, when Congress created the District of Alaska with the seat of government at Sitka, provided a system of courts, and a civil and criminal code, making the laws of the State of Oregon applicable. At the close of the nineteenth century the discovery of gold on the Klondike in the Yukon Territory of Canada caused the famous gold rush and stampede to the Territory. Accounts of the governmental activities during this peri- od vary somewhat, but it is certain that the ad- ministration was lax, in contrast to the compar- ative law and order which prevailed on the Canadian side of the boundary. Alaska was neither a secure nor a safe place in which to live or work. Lawlessness was rampant until the residents of the Territory took matters into their own hands and administered justice to quell the disorders. Although communications with Alaska had always been difficult, the influx of people caused by the gold rush created greater demands for better facilities. This was partially met by the construction of an overland telegraph llne in the Territory, under the Army Signal Corps, and laying of a cable from continental United States to Alaska. Some transportation facilities in the form of roads were provided through a Board of Road Commissioners which was created in 1905, and later through the Army Corps of Engineers. The Organic Act passed by the Congress in 1912 abolished the District of Alaska and created the Territory. Also, another important law was passed by the Congress, prior to this, providing for the incorporation of towns and for the es- tablishment of the seat of government at Juneau. In 1906, Alaska was provided with representation in Congress through the election of a delegate. The first water power development of sub- stantial size in Southeast Alaska was installed at tbe Treadwell Mines in 1882. For many years thereafter, neither the study nor the use of wa- ter power resources made any headway, inter- est being restricted principally to small proj- ects located at a few mining and fishing com- munities. The first hydroelectric public utility was constructed at Ketchikan in 1901, and the first interconnected projects were the Sheep and Nugget plants of the Treadwell Company in 1915. Stream gaging was started by private inter- ests in 1909, and by the U. S. Geological Sur- vey in 1915. The U. S. Weather Bureau materi- ·ally expanded its system of cooperative sta- tions during the same period. Interest in min- ing ran high and prospectorsfor gold frequently became prospectors for power for the purpose of operating the intended large mining ventures. Of the many power sites "staked" in this re- gion, at least two were sold for sums reputed to be "five figure prices." Both of these in- cluded a ''hanging lake" reservoir site within WATER POWERS OF SOUTHEAST ALASKA v reasonable distance of a power house site lo- cated at tidewater. The existence of hanging lakes in glacial valleys has long been known, and some were shown on the early maps of the International Boundary Commission; others were reported by prospectors, trappers and hunters. The inclusion, between 1904 and 1909, of most of the lands of Southeast Alaska within the domain of the National Forest resulted in the initiation by the Forest Service of a long- term inventory of resources, including water power. Forced by budget limitations in 1921, the U. S. Geological Survey withdrew its water resources representative from this field, and the Forest Service undertook the stream gaging work and still maintains a few controlled stations. Congress enacted the Federal Water Power Act in 1920, and the Federal Power Commission made the Forest· Service responsible for the field administration of the act in Alaska. In 1921, the Forest Service assigned J. C. Dort to study the water power resources of Southeast Alaska, which resulted in the '' Dort report", published by the Federal Power Com- mission in 1924. Since then field officers of the Forest Service have carried out as many re- connaissance surveys of water power sites as time permitted, while carrying on their routine wort. Occasionally funds were made available by the Federal Power Commission to assist in this work. A large portion of this work is brought about by the necessity of field checking the surveys made by applicants for power sites. The aerial photographic surveys of Southeast Alaska made by the United States Navy in 1928 and 1929 have recently added a useful record to the fund of knowledge. The Geological Survey has translated nearly all of these records to drainage maps. In some instances, supplemen- tary ground work has been carried out and more detailed contour maps prepared. The photographs have disclosed hundreds of little known and unknown lakes, many of them appar- ently having good power possibilities. These prints are filed in the Regional Office of the Forest Service at Juneau. In summing up this brief history of the area, it may be pointed out that many of the major proble-ms in ·Alaska are much the same as they have been, ever since the period of the Russian occupation, except that improvements have been made in transportation by air and highway, cable, radio and radiotelephone communications, especially during World War D, which will in turn help to initiate natural resources develop- ment.

':·· DESCRIPTION OF REGION I GEOGRAPHY Southeastern Alaska includes that large group ol coastwise islands named the Alexander Archi- pelaco after a Russian Gzar, by the Coast Survey in 1867, and a narrow strip aloni the mainland lrtng between the northern part of British Colum~ bia and the Pacific Ocean. The southern end of this area is in latitude 55° north, and the northern end at the Chilkoot Pass is almost 600 north lati- tude, while it extends east and west from longi- tude 130° to 138° west. Few reaUze that south- eastern Alaska is approximately 400 miles to the west of SeatUe, the general impression being that it is nearly north. The western shore -line of the United States runs practically due north and south between San Francisco and Seattle,. but beginning at Vancouver Island, the coast-line bends sharply to the northwest to Yakutat Bay and Prince William Sound, where for a short distance it swings to the west and then to the southwest along the Aleutian Islands. Southeast- ern Alaska is nearly 400 miles loag and about 120 miles in width from the canadian Boundary to the western shores of the islands. Its greatest length is 550 miles from the southeast to the northwest corner of the zone. The boundary line, between Alaska and Canada follows the thread of , Portland Canal northerly for 100mHes tothe c•-, nal bead, then strikes in a northwesterly direc- tion from peak to peak of the high coastal mOW)-. tains to Mt. St. Elias and the 141st meridiaD. f This region is in approximately the same latitude as the British Isles and the southern part of Norway and SWeden. This section of Alaska resembles Norway in many ways. Soath- eastern Alaska is a relatively small part of UMt Territory which has an area of uearly 800,00() square miles. The region comprises a matnland strip and an archipelaco. The mainland contains 60 percent of the toal area of 35,527 square miles. This area is aaly slightly less than the area of the New England States. The island JI'OUP is 300 miles long and has hundreds of islands, of which 65 exceed 4 square mUes, .. 15 exceed 100 square miles, 6 exceed 1,000 square miles and the largest ot these, Prince of Wales· Island, is 2, 770 square miles in area. The other larp is- lands are Chichagof, 2,062 ,square miles; Admi- ralty, 1, 709 square miles; Baranof, 1,631 square miles; Revillagtgedo, 1,134 square miles; ,and Kupreanof, 1,084 square miles. There are many smaller islands such as Kuiu, 773 square miles; Etol1D, 340 square miles; Dall, 263 square miles; Wrangell, 216 square miles; Mitkof, 204 square miles; Zaremba, 183 square miles; Kosciusko, 1 '72 square miles; Kruzof, 168 square miles; and Annette, 127 square miles. The islands are separated from each other and the mainland by an elaborate patter a of in- land seaways known as sounds, .straits, canals, inlets, bays, narrows, arms, channels, coves, anchorages and harbors, witb nearly all of these features being navigable bJ small craft, while the principal ones are safe for large steamers. 'rhere are 9,000 miles of shore-line along the islands and ma1Dland, making them accessible for exploration and development, only loeal road systems being necessary. For the most part, the coast-line is rocky and steep, but there are a few sheltered ;ulcborages for small craft 10 miles in extent. Some of the details of the coast- line are shown oa the ch&rts of the Coast and Geodetic Survey, but of recent years considerable mapping from the air has been carried out and there are a few air photograpb8' available-for study. There are 3 national monuments 1D southeast Alaska. The Sitka National Monument comprises about 57 acres of great natural, beauty and his- torical interest. Old Kasaan National Monument has an area of 38 aeres, preserves the Indian Villaceof Baida and is located on Pr1DeeofWales IslaDd. The Glacier Bay National Monument comprises some1,820square miles and includes a number of tide,water glaciers of the ftrst rank in a setting of magnificent snow-capped mountain r1.111es. TOPOGRAPHY 'I'he mountai.itous topography of southeastern Alaska, with its assoetated forests, glaciers, waterfalls, and fiords, has a scenic beauty com- paraole to that of Switzer land and Norway and is one of the economic assets of the region. The uea is famous for its ma,intficent fiords. These fiords are thought to be former river valleys which were eroded and deepened by the glaciers and ice currents. There is a maze of deep, in- tricate, inland waterways which thread among the thousands of. islands of the Alexander Arcbi- pelago. The seaways are generally deep and have· hard rocky beds. The deepest will exceed 400 feet. A steamer may proceed from Seattle, a thousand miles to Skagway, through whf&t is known as the "inside passage", without once entering the open ocean. This passage is a fa- 2 WATER PO\VERS OF SOUTHEAST ALASKA mous tourist route~ equivalent in origin a:nd scenic character to the famous fiords of Norway. Coast charts are available for most of the sea lanes, and the principal channels have been wire dragged, and many aids to navigation have been installed. The area is filled with fiords which penetrate into the gigantic heart of the Coast Range. Cliffs rise sheer from the water's edge to altitudes of 2,000 to 5,000 feet, and a short distance from the shore-line, snow covered peaks of 6,000 to 7,000 feet high are common. High peaks, like the Devil's Thumb, which rises to a height of 9,077 feet and with a shaftof 1,600 feet projecting above the general level, are visi- ble on a clear day for a hundred miles. 'Mt. Fair- weather rises to a height of 15,300 feet. Thousands of small glaciers occUJ' in the mountains, some clinging to steep slopes and others continually faHing in broken masses into the sea. Some of these valleys discharge ice- bergs. Here and there waterfalls, starting hun- dreds or even thousands of feet high on the moun- tain sides, plunge through a series of cascades into the valleys, or into the sea. SO steep are many of the mountain. slopes that great land-slides are a common sight, and long trianplar scars, both old and recent, are a feature of many views. The c011trasts of color afforded by the green of the forest 011 the lower slopes, the dark to llaht grays of the bare rock, the talus abov:e the timber line, the white snow patches, -and the glaciers lend ever changing variety to the scene. In the general vic1n1ty of the tnteruUoaal boundary, all the divides are filled with ice. The ridges are covered with snow and tee caps. These are the starting points for many glaciers, some of them 20 to 30 miles loaa. There are thousands of small alpine glaciers present Oil the maialand,· and there are many on Baruof and Cbichqof Islands. • The largest rivers Ol'igtate in the interior plateaus of Canada and haft cut their way through the cotstal ranp. The 4 priDcipal rivers are the stiltiDe, Whitiag, TalaJ and Klehini. Other important rivers with their trtlnat8rtes are the Salm.OD, Cbictamta, Unuk, Speeland Chlltat. Of these 9 rivers, only the Speel River bas beea iD- vesUgated as to their power posstbWties and there are no data available from which to make an estimate. Prom a general study of the map of the rivers whteh flow through the casta~ ranee, it would be strance 1Ddeed, if poteaUal power sites were not available, especially so if Canada and the United States should eventually plan to develop them as basin projects. The crest of the mainland is largely within 25 miles of tidewater and the intervening area is divided into hundreds of watersheds, varying in size from 200 square miles, such as the Speel River basin, down to a fraction of a square mile. At present, some of the upper reaches of these streams are inaccessible as far as immediate use is concerned. Even a survey other than by aerial photography Is not readlly possible. Some of these streams pass through valleys ln which there are a series of "hanging lakes" which were left by the glaciers. Some of these lakes are not far from the shore, and afford excellent water~ storages for power purposes .. The mouths of the larger rivers, particularly the 4 large mainla.Dd streams, have great deltas. Glacial moraines and t1lls have also produced flats and drumlins. These areas form the prin- cipal potential agricultural areas, ancl are almost a neglllible part of the whole region.. Some of the smaller deltas, or tidal sh<».ls, offer sites suitable for the purpose of establishing commu- ntUes, establtshments, docks aad anchorages. GEOLOGY There Is a compendium on the geological research and miaeral deposits of the southeast Alaska region iD Bulletin 800, published by the U. 8. Geological Survey in 1929. This bulletin should be coosulted by those who anticipate ex- p-oring for minerals tD this area. The report is accompanied by a reconutssaace geologic map of the SOilthern and eastern part of southeastern Alaska. This is the Ollly part of the area so far covered iD sufficieat detan to warrant the pub- lication of such a map. Ollly generalizations are included here. The classified rocks are the Ordovician sed.,. 1ments, metamorphic-sedimentary graywacke, greenstoae aad schists. Some of these may be of the Cambrian Period. The older rocks are more widely distrtbu.ted iD the southern half of the area. The Ordovician period followed the Cambrian aad marks impcrtantgeographte changes, such as the emergence of great areas of land in North Amer- ica. The earltest known vertebrate and fish re- mains occur iD rocks of this period, and crypto- gamic plants almost certa.lJUy fiourlshed. The cambrian rocks are next below Ordovician and pertain to the earliest division of the Paleozoic era. Tbe Cambrian formattcms of conalomerates, . , r.· DESCRIPTION OF REGION 3 sandstones, shales and limestones indicate, in general, conditions of shallow sea water and a period of jp"eat duration. Plant f~:~ssils are scarcely recognizable, but the record of animal life indicates that the larger part of animal evo- lution was accomplished in pre-cambrian times. Every great animal type except the vertebrate is represented in the fossils of the cambrian. The age of the beds in Prince of Wales and the neighboring islands are based on the dozen collections made by A. F. Buddington and Theo- dore Chapin, authors of Bulletin 800, and the fossils were identified by Ruedemann, of the New York State Geological Survey. Limestones and marbles are common to the beltof island areaextendingfromDa.ll andPrince of Wales Islands through-to the Glacier Bay Na- tional Monument, and lying west of Clarence Strait, Stephens Passage and Lynn canaL The sedimentation and metamorphosis action continued through the Paleozoic era into the Jurassic period of Mesozoic era. Following the Jurassic period the beds show increased amounts of material from the intrusions of the Upper Jurassic and Lower Cretaceous period. The Mesozoic era is the age of reptiles. The strike of the beds is to the northwest. It is the direction of a line formed by the intersec- tion of a bedding plane, vein, or fault with a hori- zontal plane. This strike forms the principal axis of the larger islands and the longer mountain ranges which are so much in evidence. The t.n: .. trustves also lie to the northwest and cover over haU of the area. The larger number of potential water power sites on these islands appear to Ue in this intrusive area. BuddlngtoD in discussing the general character states tbat, "The Upper Jurassic or Lower Cretaceous intrusive rocks are the dominant geologic feature· of southeastern Alaska. They are but a part of a great composite batholith and its satellitic intrusions that extend for more than 1,100 mUes northwestward into Yukon Territory from Fraser River in British Columbia. From Vancouver to Skagway, on the mainland, the batholith forms the backbone of the Coast Range and is exposed either at the shore- line or not far inland. The term 'batholith' is applied to~intrusive igneous bodies that occupy considerable areas and show no observable evidi- denee of bottom. The Coast Range batholith is the largest on the North Amer lean continent. It is much wider south of Skeelia River in British Co- lumbia than north of it, and reaches a maximum width of 110 miles. The part of the main batholith in southeastern Alaska and the adjacent strip of British Columbia is 35 miles wide, averaging about 50 miles, and is about 350 miles long. "The rocks of the batholith are often called by the general term 'granite' or 'granodiorite', as it is difficult or impossible in the field to distinguish their character more precisely. Detailed exami- nation, however, shows that only a relatively small proportion of the batholith is true granite; that is, a quartzose rock, in which two-thirds or more of the total amount of feldspar present is potassic feldspar and in which the plagioclase is a sodic variety." The Lynn canal, East Behm Canal, and the longer bays and inlets extending east from Clarence Strait and Stephens Passage intersect and continue into the batholith exposing a steep shore-line and making it possible to observe the character of the rock. A bathollth forms the spine of rugged Baranof Island, crosses Chichagof Island with lesser peaks and reaches its climax in the Mt. Fairweather and St. Elias ranges. This batholith belt, however, is modified as compared to the Coast Range. The rocks of this belt differ in general from those to the east in that they are pr.edominantly diorite rather than quartz diorite. Air photographs show extensive faulting or diking of intrusives along ltp.es parallel to the northwest trend. The surface contacts of the various beds are irregular and frequenUy are sheeted intrusives. This means the body of rock is long and wide com- pared to its thickness and in general may lie in a horizontal attitude. It is this sheeted intrusive that is mineralized, and the mineralization is dis- seminated. Alaska has been made famous in his- tory for its gold production. Some other minerals, however, in due time may take their proper place in the mineral production of the area. Apparent- ly from the meager exploration which bas taken place, · there are many minerals to be found in southeastern Alaska. How rich and extensive are those minerals has stUI to be determined. A. H. Brooks, author of "The Future of Alaska Mining1 ', a u. s. Geological SUrvey Bulletin, 714, published in 1921, states that "Anniferous lodes in Alaska have yielded $92,000,000 worth of gold, of which more than 80 percent has come from the stx large low-grade mines of the Juneau district. • • • Suc- cessful lode mining at Juneau in complete contrast to most of the placer operations, has been based on the exploitation of low-grade deposits oo a very 4 WATER POWERS OF SOUTHE.AST ALASKA large scale. The mines have, indeed, been oper- ated at a lower unit cost than any others in the world. The average value per ton of gold and silver recovered from ore produced in these mines from 1882 to 1919 is $1.95. The small margin of profit was offset by the very large tonnage handled. '' The largest ore deposit being worked is that of the Alaska Juneau Gold Mininc Company and it consists of a broad belt of parallel low-grade lodes. The ore contains about 0. 05 ounces of gold per ton and the selected ore for fine milling, about 0. 09 ounces per ton. The country rock, at the contacts, is a band of metamorphic igneous schists, several miles in width, varying along the long axis from siliceous to feldspathic and chlorite schists, with occasional metamorphic sedimentary interruptions, and varyin& trans- versely from highly calcareous rocks atthe con- tact to slates, graywacke, and greenstone. There are similar belts of less regularity and extent bordering the insular intrusives. It is not intended to go further in the mineral- ization of the rocks to be found in this area, except to point out that. other than gold, silver and lead combinations are usually present in nearly all gold lodes. There are many other minerals of value which have not been extensively mined. These mineral-bearing rocks contain molybdenum, nickel, copper, palladium, iron, chromium, zinc, tungsten, antimony, titanium, arsenic, bismuth, gypsum, garnet, barite, graph- ite, mica, quartz, and carbonates. There are -many other mineral types of rocks which in due time may be worthy of mining. In connection with power projects, it should be pointed out that good foundation rock invari- ably exists. The highlands are generally formed of crystalline rocks which present excellent foundations at nearly all of the dam sites. Local conditions such as width and shape of the valley and the extent of detrital materials occasionally nullify the foundation value. These conditions are usually mentioned in the repo•t describing the project. The character of detrital and delta fines lo- cated near the project would influence the selec- tion of the type. of construction for a particu- lar site. Delta materials brought down from interior plateaus· and found at the mouths of the 4 large mainland rivers, contain silt, clay, bio- tite and humus, all of which would have to be re- moved before it could be used in concrete. The natural grading is sheeted and the beds of clean sand are so thin as to make its recovery expen- sive. However, there are occasional bars of clean sand to be found. In the other mainland streams which lie between Portland Canal and Thomas Bay there appears to be many excellent sand deposits of beach sands near the mouths of these rivers. This sand can be recovered with a minimum of washtnc and screening. North of Thomas Bay similar conditions of beach sands are found only at the heads of the inlets which extend deeply into the mainland. The aggregate conditions on. the islands are similarly related to upstream geology and good sand deposits are r~e. CLIMATE Southeast Alaska lies in a latitude which is normally associated with severe weather condi- tions. However, variations in temperatures throughout the region depend less upon latitude than.upon exposure to the warm winds from the sea and the cold winds from the continental in- terior. Those areas lying immediately along the cQast-line, where the inhabitants usually live, have a mild climate. The annual precipitation is relatively hig11 as compared to the States, and the rainfall varies widely in different localities. The coast-line winters are comparable to some conditions which pertain to the Atlantic seaboard from Washington to Boston. The monthly mean temperatures vary from 29° to 350 andrangefrom -150 to plus 500 Fahrenheit. The temperatures taken at higher altitudes are much lower, causing ice to form on the lakes 4 feet thick, at l ,000 foot elevations. This temper- ature tends to suspend all natural flow in the streams for several months, except as they are fed from lake storages. The mean summer temperature at sea level lies between 500 and 550 Fahrenheit, with slightly higher means at h~her elevations up to the 1,000 foot elevation; tiiJn lower means will occur with further in- creases in elevation up to the point of the per- petual snow line. The climate is discussed more fully ill Part n of the report. POPULATIONS AND COMMUNITIES Prior to the Second World War the population of the Alaskan Territory was in the vicinity of 75,000 people. They were broadly classified as about 3, 500 Eskimos, 34,500 Indians, and 37,000 Whites, according to Colon61 and Mrs. William DESCRIPTION OF REGION 5 Albee, who have worked among all of these groups and taught the Eskimo children at Cape Prince of. Wales. The Indians included a large number of mixed bloods. This is a density of approximately 1 person for 8 square miles d. territory as contrasted with 44 persons per square mile in the States. ' In southeast Alaska there were 25,241 people according to the 1940 census, exclusive of mem- bers of the a.,-med forces who were stationed in the area or wer~ carrying on surveys and con- struction work. This is an approximate density of 1 person per 1.5 square miles. However, this population is <;.oncentrated in 8 centers and many small fishing and mining communities. The 8 larger communities had a population of 15,530 people according to the 1940 census. This was an increase of 6,843 persons or 75 percent over the1920census of8.887 persons. The1940 cen- sus shows a population~ 5. 729 for Juneau; 4,1lH for Ketchikan; 1,987for Sitka; 1,162forWrangell, 1,232 for Petersburg; and 834 for Skagway. Skagway at the northern end of the area is the railway terminus at the seaboard for the White Pass Railway. Juneau is the capital of the Territory and the distributing center for the north end c1 this region. It is also the location of the Alaska Juneau Mining Company. Douglas is opposite fuaeau, across the Gastineau CbaD- neL The plant of the Treadwell Mining Company was located near Douglas. Sitka was the first capital of Alaska 'and is located on the west coast of Baranof Island. Sitka ha.4l many points of his- torte interest and valuable relics of the Russian occupation. A division station d. the Agricul- tural Experiment Station of Alaskan Territory is located at the town of Petersburg. Wrangell and Petersburg are supply centersofthecentral portion of the region, ud the former is also the supply and outfitting station for the expeditions moving into the Stikine River region. Ketchikan is the first port of entry in southeast Alaska, and is the distributing center for the southern region. There are many small native villages, and scores of small settlements at or near cuneries and mines, which have a regular mail service and where boat supplies, 1uel, food and clothing can be purchased. COMMUNICATIONS Transportationfacilities on land insoutheast Alaska are poorly developed and are likely tore- main so for an indefinit~ period. The rugged nature of the land with its many swampy areas, muskegs, luxuriant growth of vegetation, num- erous fiords and deep channels that separate the island and much of the mainland, preclude the extensive construction of railroads and highways or even wagon roads, except at high costs. It is possible, however, that in the near future con- sideration will be given to connecting the main- land of southeast Alaska by a road with the A- laskan Highway. However, the need for railroad construction is in large measure obviated by the intricate oattern of natural waterways which pen- etrate the region. These channels provide ex- cellent highways for deep sea vessels and num- erous deep water harbors in sheltered bays for their anchorages. STEAMSHIPS Prior to World War U, ·regular. steamship service was maintained by coastwise steamers all the year round from Seattle and Vancouver to Ketchikan, Petersburg, Wrangell, Sitka, Juneau and Skagway. In the summer season, tourist boats . leave Prince Rupert and Seattle for the major ports of southeastern Alaska and to visit the gla- cier bays and scenic beauty of the region. Prior to World War II boats ran regularly from Ketchikan carrying mail, passengers and freightto settlements on the west coast of Prince of Wales Isiand. Similar service was maintained from Juneau to Fans haw Bay, Windham Bay, Sum- dum, Snettisham, and Taku; from Petersburg to Kake; from Juneau to Auke Bay, Tee Harbor, Eagle Landing, Comet, and Skagway; and from Juneau to Tenakee, Gypsum, Hoonah, Chichagof, Cape Bdward and Sitka. There were 5 steamship lines which were operated between the region and Puget Sound, with an average of 8 combined passenger and cargo steamers each week during the summer, and 3 during the winter. The steamship lines were as follows:. 1. Alaska Steamship Company, Seattle. 2. Northland Transportation Company, Seattle. 3. Alaska Transportation Company, Ta- coma. 4. Canadian Pacific Company, Vancouver and Seattle. 5. Canadian National Railways, Van- couver. The Canadian lines called at Prince Rupert to pick up and discharge passengers and cargo. 6 \VATER POWERS OF SOUTHE:\'IT ALASKA • • 0 6. ' ··skagway • • \. ...... LEGEND A. C. S.

The smaller towns and cannery camps were served through the operation of weekly or bi- weekly mail boats, and they usually had limited passenger accommodations. Some of the smaller communities have docking facilities used for steamers taking on special cargoes, such as lum- her and ores. The transcontinental railroad ending at Prince Rupert, B. C., reaches within 32 miles by air line of Sitklan Island of southeastern Alaska. Prince Rupert is 104 statute miles by water from Ketchikan, the leading industrial center of the southern portion of this region. SeaWe, the most important water gateway, is 7S7 miles by water from Ketchikan, 8S9 miles from Wrangell, 907 miles from Petersburg, and 1,033 mileF from Juneau. Skagway and Sitka are usuaJly reached via Juneau. The steamer trip from Se- attle requires 45 hours to Ketchikan, and 70 hours to Juneau. AIR lAYS Great strides have been made in linking up all of the larger communities with the United States in an improved aJr service and especially duringtheSecond World War, as wellas the past decade. This service reaches Juneau both from Seattle and the Whitehorse-Skagway route. The Pan American airways route is established from SeaWe to Ketchikan, Juneau, Whitehorse and FairbankS. A Canadian company connects White- horse with Edmonton for points east. It was re- 'ported by the Civil Aeronautics Board that some 35 air routes served many parts of the Alaska Territory. Many of these routes have been con- solidated. There are 3 licensed airway groups serving about SO places in southeast Alaska with regularity, and some have daily service. The Pan American has 3 plane schedules per day each way. This company uses landing fields while the more local services land and take off from the water. The local licensees as reported by the Civil Aeronautics Board are the Alaska Coastal Air lines, Ellis Air Transport and Petersburg Air Service. RADIO AND TELEGRAPH SYSTEMS The accompanying map shows the communi- cation system which is in operation in southeast- ern Alaska. This system has been gradually in- augurated over the last 30 years, but the major portion has been developed dur ir.g the last dec- ade, and especially during the war. The system is largely owned and almost entirely operated by the United States Government through the Signal Corps, U. S. Army. Alaska Communication System radio circuits are operating through the Juneau station from Skagway, Haipes, Excursion Inlet, Sitka and Se- attle. It also is operating through the Ketchikan station from Petersburg, Wrangell, Craig, Ann- ette and Seattle. There are many radio, tele- phone, radio telegraph, government land line and commercial land line circuits which make con- tacts with. more than SO other. stations on the islands and mainland. These connect all of the principal communities and mining camps with the outside world. The first public radio telephone circuit be- tween Alaska and British Columbia was inaug- urated on July 12, 1946, connecting Ketchikan, Alaska, with Prince Rupert, British Columbia. Thefirstdirectcommercialradio telephone cir- cuit connecting the United States and the Aleutian Islands was inaugurated between Seattle and Adak, Alaska, on July 13, 194S. A direct commercial radio telephone circuit was established between SeaWe and Nome on July 24, 194S. This is some indication of the improvements that. are taking place. A second commercial radio telephone channel was established between Anchorage and Seattle August 31, 1945 for the purpose of handling the increased traffic. A submarine cable circuit be- tween Ketchikan, Juneau and Petersburg was con- verted from simplex to full duplex and placed in operation September S, 194S. These general im- provements in the communication system will have a direct effect on the operation of many com- mercia! establishments which are going concerns. FLORA The greatest proportion of the area of south- eastern Alaska is under the domain of the Tongass National Forest, which is administered by a branch of the United States Forest Service, re- sident in Alaska with headquarters at Juneau. Those 'who have an interest in the development of this region and especially in the forest reserves are referred to "Pulp-timber Resources of Southeastern Alaskatt, by B. F. Heintzleman, Regional .Forester, published by the Department of Agriculture as Miscellaneous Publication No. 41, in 1928. DESCRIPTION OF REGION 9 ''Southeastern Alaska is within the range of the extensive 'coast forest', which occurs in western Oregon, Washington, and British Colum- bia and along the southeastern coast of Alaska, as far north and west as the Aleutian Peninsula and Afognak Island. As thts coast forest pushes northward from the most favorable part of its range in Washington, it gradually loses some of its species, the timber line decreases in altitude, the trees become smaller and the species of the higher elevations gradually work their way down toward sea level. ''As found in southeastern Alaska, the coast forest is predominantly a mixed stand of Western Hemlock and Sitka Spruce. In many places Wes- tern Red Cedar and Alaska Cedar are associated with the predominant species in small proportions. Any of these four species may be found occasion- ally in a pure stand of small extent. The for- ests have an almost tropical density of trees and underbrush. In the usual mixed stand hemlock with some cedar forms a dense main cover, and this is overtopped by the more light-demanding spruce, which occurs singly or in small groups. Small bushy saplings of the shade-resistant hem- lock and cedars, various species of blueberry Waccinium> and devil club <Echinopanax horrida), and other shrubs form a dense understory. Down timber, which decays very slowly because of al- most continuous saturation from an abundant rain- fall, occurs in profusion, and a carpet of moss often 6 inches or more in thickness covers the decaying logs ·and the entire forest floor. "The stands of timber are even aged; many age classes are represented in the forest as a whole; and the stands of the older age classes are greatly in the majority, perhaps three-fourths of the commercial timber of the region being mature and over -mature. The even aged stands are char- acteristic of western Hemlock and Sitka Spruce; the greater number of age classes and the pre- ponderance of old timber are to be expected in an extensive virgin forest. "The average stand per acre for the com mer- cial forests as a whole is about 25,000 board feet, but the individual logging units vary widely from this average. A volume of 30,000 and 40,000 board feet per acre is common on many extensive areas, and 50,000 feet or more per acre frequently occurs on small units. The majority of merchan- table trees are from 2 to 4 feet in diameter and from 90 to 140 feet in height. ''The forest cover extends from the edge of tidewater to an altitudinal limit of about 2, 750 feet in the southern part of the region and 2,000 feet in the northern sections. At an elevation of about 1, 500 feet, the commercial timber gives way to stands of dwarfed, limby trees, which are designated 'subalpine' and classified as non-com- mercial. Because of the prevailing steep slopes the commercial forests form relatively narrow bands aldng the shore lines of the mainland and islands, rarely extending more than five miles inland except along the valleys of the few large streams. "It is estimated that 75 percent of the com- mercial timber lies within 2 1/2 miles of tide- water. "The forests of commercial .value are broken into large blocks by frequent extensive non-com- mercial areas of 'scrub', as the open stands of somewhat dwaTfed timber are called, and by mus- kegs of peat which carry only isolated small trees. "Trees with dead spike tops are a conspic- uous feature of the non-commercial scrub areas and of the cedar areas. Spike-topped individuals, so decadent as to be classed as unmerchantable, are fairly pre .valent also in the over -mature hem- lock-spruce stands, but their effect in depreci- ating the .value of these stands is likely to be over- estimated. They form a relatively small per- centage of the timber which as a whole is of good quality. Only a few spike tops occur in the ex- tensive hemlock-spruce areas of mature timber and of piling-sized young timber." It is a common sight to see spruce trees 7 feet in diameter and 200 feet high. It is conser- vatively estimated that of the 4 principal species, Western Hemlock, Sitka Spruce, Western Red Cedar, and Alaska Cedar, there is a total com- mercial stand of 80 billion board feet, of which 98 percent is within the Tongass National Forest. INDUSTRIES The principal industries of southeastern A- laska, bath existing and potential, are fishing, mining, forestry products and recreation. These resources are presented in the report," Alaska- Its Resources and Development", Part VU, pre- pared as one of a series of Regional Planning Studies, by the National Resources Committee, at the request of Franklin D. Roosevelt. FISHING The fisheries of southeastern Alaska which are approximately half of this particular indus- 10 WATER PO\VERS OF SOUTHEAST ALASKA try in this region present a brilliant example of a successful conservation policy. The improved methods established will continue the annual catch indefinitely. This industry shows more than 800 percent increase in the annual fish pack during the 40 years following 1899. While salmon is by far the principal fish taken, there are others of importance such as halibut, herring, crab and shrimp. Other aquatic life are important also, such as the protected seal and otter catch. Whal- ing has been carried on in a very limited way. Along the bays and inlets of the islands and on the mainland, canneries and fisheries have been established which in due time may become a na- tive labor industry, rather than operated by im- ported labor from Seattle and the Puget Sound area. At present only a very limited amount of water power is used in connection with salmon canneries, but as the freezing methods become more established in the handling of the pack, this power load may take on a significant figure in the consumption of energy. Salmon fishing has reach- ed stability and due to its basic importance ~11 good salmon spawning streams must be safe- guarded and their utilization for other purposes can only be permitted under careful regulation. The fishing industry itself has developed small hydro power units to replace fuel power in non- spawning streams. To develop a small hydro is usually not difficult as a large supply of fresh water is required for canning, and hydro power can usually be installed on the same conduit with little additional expense. MINING It is apparent fr"tlm the extensive work in min- eral studies during the century that Alaska holds vast potential reserves of minerals, as yet un- developed or scientifically explored, which will contribute to the national welfare. Southeastern Alaska has a good share of these minerals accord- ing tothe Geological Surveys that have been con- ducted. There undoubtedly will be a considerable increase in mining as soon as more accurate knowledge becomes known as to the minerals. Lode mining for which Juneau has become famous, is the second largest basic industry of the region in point of the number of persons which are di- rectly engaged. Its present and probable future ener~y requirements far exceed that of the fish- ing industry. Low grade ores are the rule and low cost energy will be a prime consideration in the development. This industry has prospects for large expansion in the vicinities of Hyder, Thorne Arm, Kasaan Bay, the mainland from Bradfield Canal to Berners Bay, the Mansfield Peninsula of Admiralty Island, the northwest portion of Chic- hagof Island, Krestof Island, the Yakobi Islands, and in several other areas. FOREST PRODUCTS The saw-mill capacity of southeastern Alaska is largely geared to the local demand, supplying such types of timber and lumber as are used in the fishing and mining industry. During the First World War some high-grade Alaska Spruce was produced for airplane construction. Hemlock piling may offer some opportunity for expansion, since the Second World War has seriously de- pleted the supply from other sources. A market is available for the Western Red Cedar poles. Shingles are manufactured at two plants, largely for local consumption. The future of this in- dustry could be expanded if it becomes a by-pro- duct of lumbering. The same can be said for poles although it would be practical to produce them alone in some areas. However, nearly all of these materials will necessarily have to be shipped long distances to market. The forest resources of southeastern Alaska will undoubtedly be used chiefly for manufacture of pulp for the chemical industries and for news- print paper. Unusually favorable conditions exist there for the large scale operations which char- acterize the industry. When this industry is estab- lished, great precautions must be taken in order that none of the waste liquors from the pulp plants are permitted to pollute the waters and destroy the fish life. The policy of the Forest Service is to limit the development of pulp and other wood- using plants which are dependent upon national forest timber to the total capacity that can be supplied indefinitely through tree growth, and thus insure permanent industries for this region. This policy prevents over -development and subsequent collapse through timber exhaustion that has char- acterized timber industries in many sections of the United States. This is highly important to the paper industry itself, which has a heavy invest- ment in plant and machinery. Studies by the Forest Service indicate that under a proper sys- tem of management, the forests of this region can produce not less than 1,500,000 cords of pulp- wood annually in perpetuity. This represents a production of 1,000,000 tons or more of news- OESCRIPTION OF REGION 11 print, which is about 25 percent of the yearly consumption of the United States. There is also a heavy demand for plywood timber, a part of which can be supplied from this area. The entry of these industries into south- eastern Alaska maybe sudden ratherthan grad- ual, and therefore the need for power will be large as the pulpwood and plywood industries are heavy users of power. The building of communities will also create a demand for utility power for services. RECREATION Recreation facilities are rapidly becoming popular for the tourists, but their consumption of energy will be very meager. Similarly, the naval, military and other Federal bureaus are increasing their demands for utility services, but none of these establishments are likely to develop very large demands for power as compared to the establishing of forest products industries. WATER RIGHTS There are no Territorial or Federal statutes in effect governing the appropriation of water. There are several organized mining districts having codified rules and regulations. However, the Courts have not completely accepted them. Common law, as expressed in McFarland, et al v. Alaska Perseverance Mining Company 5ee Alaska Reports, First Division, Juneau, June 3, 1907, page 308, et seq.> recognizes the principles of priority, beneficial use, the highest use, and negotiability. A mining district priority for a water right for a mining operation is establish_ed by posting a notice of claim at the point of propost!d diver- sion of a stream, and by filing a copy thereof, attested by two witnesses, with the Recorder of the district and within a reasonable time there- after, the water must be put to beneficial use. The priority dates from the notice, but the right • does not exceed the quantity claimed in the notice, nor the quantity put to beneficial use within a reasonable time. A similar procedure is generally followed for projects outside of the mining districts, or for purposes other than mining within the district. The filing is made in the office of the Recorder of the judicial district. This step is precaution-· ary and not mandatory as beneficial use without notice or filing establishes an equal right. REGULATIONS GOVERNING WATER POWER There are a few water power developments now operating in southeastern Alaska, under per- mits issued either by the Department of Agri- culture for National Forest lands, or by the De- partment of the Interior for lands of the public domain. These permits preceded the passage of the Federal Water Power Act of 1920, which as revised as of August 26, 1935, is the controlling law governing water power development on all federally owned lands and federally controlled waterways. Procedure and ·requirements for the purpose of obtaining permits and licenses governing water power development are printed in a publication by the Federal Power Commission, entitled "Rules of Practice and Regulations, With Ap- proved Forms, Effective June 1, 1938. TERRITORIAL REGULATIONS There are no territorial regulations required other than demonstrating the right to do business in Alaska. The applicant must comply with the general statutes and pay assessed taxes. Licen- sees for power development are not required to carry on business with the territorial agencies. There are no territorial regulatory body or rules or regulations governing utilities at present, but there are some municipal regulations in force whenever city franchises for public service are involved. ,.; 4> ... ~ 4> 't:l .... ... 1ii 4> .s -$.t ~ 1 5 ~ ~ .c: < Col z s Cl.l ... :::> tl.l -4> e,:, 8' ~ t:.:J -Cl.l tl.l 't:l 4> $.t 4> ~ Col t ..0 a .... ... .8 e-. :, ,_-,., CLIMATE OF SOUTHEAST ALASKA 13 GENERAL CLIMATOGRAPHY* The climate of southeast Alaska is abnorm- ally mild and quite disproportionate to the lati- tude in which it lies. The temperature of the region takes on the characteristics of the ocean close by. The precipitation ranges from tropi- cal abundance to an amount barely sufficient to meetthe needs of vegetation. Its distinctivefea- tures are not alone due to the rugged topography and its proximity to the vast exposure of the ocean to the south and west, but are also influ- enced in large measure by the great semi-per- manent low-pressure area that overlies the northern portion of the Pacific during the fall and winter months. The mean annual temperatures taken at sea level throughout southeastern Alaska are from 10 to 15 degrees higher than the annual means for the same latitudes found either in the interi- or or the eastern portions of Canada or of Sibe- ria. The interiora.nd eastern portions of the con- tinents in the same latitudes are subject to sharp and extreme fluctuations in temperature. This is not true of southeastern Alaska. The close proximity of the ocean, the numerous tidewater channels and canals that separate the many is- lands in the southeastern district, together with the prevailing southerly winds blowing in from the ocean, all help to give the region a tempera- ture which partakes of the uniformity and mild- ness which characterizes the temperature of the adjacent ocean surface. The North Pacific is a low-pressure area which reaches over the Gulf of Alaska and the Aleutian Islands region to the westward during the fall and winter. This is a factor in the cli- mate of this part of Alaska as well as of Brit- ish Columbia and the North Pacific states. It creates a marked contrast in the temperature during the seasons. The temperatures of the air masses are also affected by the warm aurface of the ocean and the snow-covered land of continen- tal Alaska and Canada. In the spring, when the snow disappears and the land surface of the inte- rior becomes heated due to the longer days at the high latitudes, the low-pressure area dies out and with it the effect of the air currents. · Southeastern Alaska lies in the eastern quad- rant of this low-pressure area and receives winds • If.

Every few days an offshoot from this main low-pressure area moves southeastward toward British Columbia or the North Pacific states. The area of high pressures overlies the great Yukon Valley during the winter. Occasionally the high pressures will push farther to the southward than usual and cause northerly winds and rela- tively low temperatures in southeastern Alaska, especially in the northern portion. In the summer season the pressure conditions are ·reversed, with the barometer normally highest over the ocean, and lowest over the heated interior, a con- dition that induces the winds to move from the southerly quarter into the southeastern Alaska area. These warm winds from over the ocean are filled with moisture and are cooled in their as- cent:of the slopes of the mountains. The princi- ple of condensation is brought into operation when the cooling of the air decreases its capacity to hold water as a vapor and the rain is almost lit- erally continuously poured upon the area. The ability of the air to hold the water vapor is de- creased 4 percent for each succeeding degree of cooling, or, conversely, it can be said that at any given temperature the capacity to hold water va- por suspended in the air is about 4 percent less than at the next higher degree of temperature. The average rate of cooling of ascending free air is about 1 degree Fahrenheit for each 300 feet of elevation. The effect of precipitation of water from saturated or nearly saturated air, as it is forced up the mountain slopes to a height of sev- eral thousand feet, is readily understood, as the entire area is filled with high mountains. Assuming the air to be saturated or nearly saturated as it leaves the ocean surface and bring- ini,lnto operation tbese condensing forces, it would seem logical to precipitate the moisture upon the slopes nearest to the sea. In the case of air that is not saturated when it leaves the surface of the ocean, the precipitation may not occur until it im- pinges upon the slopes of the mountains at eleva- tions having temperatures at or below the satu- ration of the air. Thus it may happen that a high mountain slope or range of mountains some dis- tance inland may receive a large quantity of rain whereas only a light rain.or perhaps none at all would occur on the slope of a lower mountain near- 14 \VATER POWERS OF SOUTHEAST ALASKA er the sea. However, in c-onsidering this effect of the mountains on condensation and precipita- tion, the impression should not be gained that these are the sole causes of precipitation in this part of Alaska, for there are other causes which operate also, similarly as in regions that are comparatively level. However, there is no doubt but that it is one of the fundamental causes which accounts for the extreme precipitation of this area. The climatological records and data which are available are analyzed and illustrated in the following paragraphs with the thought in mind of giving a reasonable explanation of the precipi- tationfrom the not too plentiful and rather mea- ger s·ources of information as yet gathered and assembled. LOCATION OF PRECIPITATION STATIONS The location of 50 precipitation stations are given in Table 1. All but one of these stations, namely Yakutat, are in the southeastern district. The stations listed include those which appear in the Climatological Data publication by the United States Weather Bureau at Anchorage, Alaska. It also includes several local stations which supplied data used by the Forest Service, together with one station which lies outside of this district. All but two of these stations are located on the accompanying map. These two stations are Prince Rupert, B. C., and Yakutat on an island at the northwest. The map was originated for the Army Air Forces and shows several additional precipitation stations for which data are unavailable at this time. It is difficult to keep current much of the data when they are taken at high altitude stations or 1t difficult geographic locations unless radio apparatus has been installed at the stations, There are 30 stations which report data with ·egularity and 20 other local stations in the list from which data have been used in connection with this report. Corrections in location and elevation of the stations have been made in the table since it was originally compiled, but com- plete perfection is doubtfuL It was observed that several stations may have varied a minute or more in degree from the original given data, and the distanc~ most frequently was usually about a mile. The eleva- tions from the various reports do not always agree. This was sometimes caused by making changes in location in the field without establish- ing the exact elevation. The station at Haines is reported officially as at the 30 and the 257 foot elevations without giving the date of change. Juneau Airport is listed as at the 11 and 24 foot elevation; Ketchikan as at the 15 and 17 foot elevation; Sitka as at the 15 and 75 foot eleva- tion; Tree Point as at the 36 and 40 foot eleva- tion; Wrangell as at the 18 and 37 foot elevation; TABLE 1.

CLIMATE OF SOUTHEAST ALASKA and Yakutat as at the 8 and 37 foot ele- vation. Some of these stations have been moved from time to time in both elevation and location a few hundred feet without reporting the date of change. The Kensington Station was moved from the 700 to the 2,025 foot elevation De- cember 23, 1936, butthe change in lati- tude and longitude was not given. In Sitka there are 2 locations, and it is believed they were about a mile apart. The exact location and elevation of the gage at Sitka is not known for the peri- od of April 1881 to September 1887. This means then that care must be given to the interpretation of the data as - sembled. EXPOSURE OF GAGE In analyzing the monthly and annual precipitation, it is important to give weight to the configuration of the re- gion as the catchment of the precipi- tation is influenced by the exposure of the rain gage. A change in location of the gage by so slight a distance as 300 feet may change the annual totals by 10 to 15percent. There have been several changes in the location of the precipi- tation station at Juneau during its more than 50 years of record. The apparently greater precipitation from 1917 to 1937 as recorded, is felt in part to be due to the better exposure of the gage. There is also a marked disparity between the records at the two different locations of Sitka Station, and without doubt they can be accounted for by the difference in exposure. The records made from stations of Annex Creek, Calder, Fort_.. mann Hatchery, Haines, Klukwan, Speel River, and Yakutat, as well as shorter records taken at some other stations, have been made under practically the same conditions of exposure throughout their entire periods of installation. PRECIPITATION DECREASES WITH DISTANCE INLAND In general, it can be said that the mean annual precipitation received at sea level stations decreases with dis- tance from the ocean. The annual totals METEOROLOGICAL STATIONS S. E. ALASKA 15 I ... MAP 3 , .. 16 \VATER PO\VERS OF SOUTHEAST ALASKA of precipitation range from 154 inches at View Cove to 151 inches at Ketchikan, and 148 inches at Fortmann Hatchery near the southern end of the district, to 27 inches at Skagway and 21 inches at Klukwan in the extreme northern portion of the district. The station at Little Port Walter near the southern end of Baranof Island recorded a precipitation of 253 inches in 1944. TABLE 2.

The annual run-off taken from the gaging stations data ranges from 115 to259 inches, with the average ofthese stations close to 173 inches. The annual precipitation taken at sea level sta- tions indicates the annual run-off to be from 20 to 100 inches greater than the precipitations at sea level. The average run-off is in the vicinity of 50 inches greater than tbe average precipi- tatlc:m at sea level stations. This means that the precipitation at higher altitudes is greater that at sea level. This also accounts for the high run -off. PRECIPITATION AT HIGHER ELEVATIOl\ STATIONS Only a small amount of data are available from precipitation stations located at higher ele- vations. Table 3 shows the percent increase in precipitation of higher altitude precipitation sta- tions over those taken at sea level. There are apparently only 7 stations with sufficient data to make this comparison. The precipitation at the higher altitude stations ranges from 121 to 194 percent of the sea level stations. The effect of elevation on precipitation is shown by the record at Jumbo Mine. The station· is located at the 1,500 foot elevation on the sea- ward slope. There are 3 years of records which show an average precipitation of 195.inches. The 5-year average of 146 inches of precipitationat Perseverance Camp station located at the 1,100 foot elevation shows a rainfall of 176 percent as against the 82 inches of precipitation at the sea level station located at Juneau only 3 miles away. Although Perseverance Camp is on the lee- ward slope of Mt. Roberts, which has an eleva- tion of 3,800 feet, the precipitation received at that point is believed to be nearly the same as occurs' on the crest or on .the southern slope near the crest. Records made during the months of July, August, and September, for several years, at the two elevations on the slope of Mt. Roberts, one located at the 1,800 foot elevation and the other at the 3,500 foot elevation, show the greater precipitation to be at the higher elevation, and in nearly the same quantity as recorded at Per- s~verance Camp on the leeward slope of the mountain.

Precipitation stations locatea at Camp No. 4 and Camp ~o. 6 are only a few miles from Per- severance Camp. These two camps are lo- cated at the 750 and 2, 777 foot elevation, re- spectively. The few months' records seem to indicate that the station at Camp }\lo. 4 has by far the greater precipitation, although it is situ- ated on the leeward slope of a mountain range which is nearly 4,000 feet high, whtle the sta- tion at Camp No. 6 is situated on the windward side of the slope and is 1,000 feet below the crest. The case of Camp No. 4 seems to be analogous to that of Perseverance Camp, in that the precipitation occurs in connection with clouds moving horizontally across the valley. In southeastern Alaska the elevation at which the maximum precipitation occurs has not been determined by observation, due to the lack of a sufficient number of stations. It is felt, how- ever, the 4.000 foot elevation in general marks the maximum line of precipitation. The line of course would be higher in summer than in winter. ISOHYETAL BELTS OF PRECIPITATION The Isohyetal map of southeastern Alaska shows the rainfall belts generally extend in par- allel directions from the southeastto the north- west. They follow more or less the vertical configurationof the shore line from Cross Sound to Cape Muzon. There is a dry belt which ex- tends from Icy Strait to the northern end of Clar- ence Strait. Killisnoo is situated almost mid- way between Sitka and Juneau and has a mean annualprecipitationof 50.89 inches as compared to the 85 inches at Sitka and the 83 inches at Juneau. This is further emphasized by the 14- year record at Kake located on Frederick Sound, which has a mean annual rainfall of 54.19inches. As the map indicates, the heaviest belts of pre- cipitation tend to be along the Pacific Ocean on the outer area of the archipelago and along the ridges west of the United States and Canadian boundary. The rainfall in general is heavy in all of the area except in the upper portion of Lynn Canal and Skagway. The mean annual precipitation in inches, to- gether with the percentage for each month, is shown in Table 4. There are 50 precipitation stations indicated together with the number of years of records for each station. The fourth column in the table shows the inches of annual rain adjusted to sea level conditions by H. J. Thompson, for the purpose of constructing the Isohyetal map of southeastern Alaska. This Isohyetal map also shows the run-off in inches at the gaging stations which are nearest to the precipitation stations. The numerals enclosed by the circles are the annual mean precipitations in inches adjusted to sea level at each of the respective prec::ipitation stations. The numerals enclosed by the rectangles are the obs~rved run-offs in inches at each of the gaging stations. The arithmetic mean precipitation values were furnished by the United States Weather Bureau and were adjusted by Mr. Thompson on the long period basis by comparison with the records made at Sitka. The adjustment coefficients used varied from 0. 740 to 1.040. The Sitka record aggregating about 70 years was given a coefficient of unity. The coefficient for the mean at any station A for the period P was the ratio of the 70-year Sitka mean to the Sitka mean for the period P. The necessity for such adjustment is appar- ent from an examination of the record of Little Port Walter. The total precipitation was 242.35 inches for the climatic year 1937. The coeffi- cientis 85.06 t 122.65 = .692 and the adjustment is . 692 x 242. 35 inches = 168 inches. The mean precipitation of Little Port Walter for a period of 21 months is 244. 37 inches and for Sitka , 112.62 inches. The coefficient is 85.06 t 112.62 = • 7 56, and the adjustment is • 7 56 x 244. 37 = 184 inches. It is preferable to make a comparison on the basis of climatic years due to the inclu- sion of different seasonal storms. In this case only one climatic year has been recorded; there- fore, it is necessary to give greater weight to the 21-month mean and the 180 inches taken for the long-period mean at Little Port Walter and treat them as two significant figures. Stmilar calculations were made for all precipitation stations with coefficients for periods of longer records which causes them to approach unity.

Chart No. 1 illustrates the annual variation in precipitation for a series of climatic years. Prior to 1915, the gathering of precipitation data was princi- pally dependent upon locally interested weather observers, and the records which are very use- ful for historical data show greater variations than the data which ·make up the record since that date. Beginning in 1915, technically trained observers kept the records and immediately it is evident that care in taking the record causes the curves to vary far less from normal. The annual precipitation at Juneau has varied from 80 to 141 percent from normal for a period of 23 years up to 1937; at Sitka for the same period, the range was from 90 to 142 percent; and at Ketchikan from 84 to 131 percent. Some of the stations are grouped and the means are plotted on the same chart. Similar variations from normal are to be observed for these groups. It is observed that there is less departure from the norm in· wetter areas such as Fortmann Hatch- ery than in the dryer areas such as Skagway. The curves also show cyclic variations with full periods of 11 to 13 years and intermediate sec- ondaries near the mid-period. There are also deflections of wet storms so that they miss a significant part of the region even though it may bea wetseason. Fortmann Hatcherywasmissed by such a storm in 1937. REGULARITY OF PRECIPITATION Chart No. 2 illustrates the annual variation in precipitation by comparing southeast Alaska with various locations on the Pacific Coast from southern California, north. The mean annual precipitation for 7 regions in the order of their latitude is plotted in percentages. The data for the six groups, San Diego, South Coast, Santa Barbara, Hetch Hetchy, Eureka and Grant Pass were furnished by Dr. McEwen. The seventh group on the chart is the mean of all the south- east Alaska stations, and is the rectilinear e- quivalent of the last curve on Chart No. 1. There is less departure from the norm of the south- eastern Alaska curve, as is easily observed. There is only 42 percent departure from the norm of this curve as compared to departures of the other ·six curves representing the means of the southward groups. They have departures from normof95, 110,74,100, llOand 125percent, re"" spectively. The periods of wet. and dry years of these groups are in different phase. The Alaska group is opposite in phase in every pe- riod, and there is some difference in phase be- tween the northern and southern group of Cali- fornia. This suggests that wet-air masses from Mid-Pacific barometric highs are deflected by air currents, sometimes easterly to the Cali- fornia Coast, sometimes northeasterly to the Alaska Coast, and in some years alternately in these directions, with some evidence of perio- dicity. The aggregate precipitation in the coast- al regions from San Diego to Alaska is much more nearly constant than the observations in any locality would indicate. It is also observed that long-range forecasting of California prec ipi- tation can be applied to Alaska with a reversed sign and for about half the departure from the normal. FREQUENCY OF PRECIPITATION The frequency of precipitation coincides closely with relative amounts of precipitation in the several months. Those months which have the greatest precipitation normally have the greatest number of days with precipitation. October is usually the wettest month in this re- gion and the average number of days in which precipitation occurs is 25 at Ketchikan and 14 at Skagway, while for the driest months, usually June and August, there are 16 days at Ketchikan and 6 days at Skagway with rain. Records for 46 years atJuneau show an annual average of 221 days in which .01 of an inch or more of pre- cipitation occurred, and for a 10-year period for Ketchikan and Sitka there were 240 and 206 days of rain, respectively. It should be added that thunder storms are very rare, the annual average showing less than one storm in t\\·o years at Juneau, 1.1 storms per year at Ketchi- kan, and 2.2 storms per year at Sitka. In 21 years of records kept at Juneau, ape- riod of 45 consecutive days from January 1 to February 14, 1934, shows that precipitation of measurable quantities occurred each day, while at Ketchikan for the same period of years, 1917 to 1937, from September 19 to December 15, 1920 there was a period of 88 days in which precipitation occurred. Droughts such as occur in our central states have never occurred within the period of obser- vation in southeastern Alaska. In the 21 year~ of observation at Juneau, the longest period 20 WATER PO\VERS OF SOUTHEAST ALASKA without a measurable quantity of precipitation, excluding one day with 0. 01 of an inch, was 24 days, and occurred from July 3 to 26, 1920, while at Ketchikan the longest period was 21 days and occurred from July 21 to August 10, 1924. It should be noted that the largest percentage of precipitation occurs during the months of September, October and November, frequently being 35 percent of the annual. The percentages of the total precipitation usually range from 12 to 18 percent for each of the months of October and November. In many instances the precipi- tation continues into December and January, frequently ranging from 10 percent for each of these two months. As a general observation, at least 50 percent and sometimes 60 percent of the annual precipitation occurs during the five months of September through January. Moderate precipitation of 15 to 20 percent of the annual occurs during February, March and April. In general, it also may be observed that about the same percentage of precipitation occurs in Au- gust as in February. The least precipitation occurs during the months of May, Jur.e and July and ranges from 10 to 15 percent of the annual. May and June, especially June, are the driest months. The June average ranges from 3 to 6 percent of the yearly average. However, there are wide departures from these average con- ditions but it is felt that such variations are no greater in extent than is common to the states. The highest recorded monthly precipitation in southeast43rn Alaska, or even in the entire Territory, is 61.41 inches which was recorded at Jumbo Mine for the month of November 1917 • There have been several instances where only a slight trace of precipitation has occurred in a calendar month in the northern part of the dis- trict, but there are no months in which precipi- tation has not occurred. A study of the tables reveals that the sta- tions with the longer records show that the pre- cipitation of the wettest years ranges from 20 to 65 percent above the normal years for these several stations, while the driest years may show a range of 10 to 44 percent below the nor- mal years. INTENSITY OF PRECIPITATION The intensity of precipitation ranges from 1.05 inches in November to 0.4 of an inch in June at Ketchikan, to 0.25 of an inch in Septem- ber to 0. 09 of an inch in June at Klukwan. The intensity is the average amount of precipitation per rainy day, At Ketchikan 8.07 inches of rain have been recorded in a single 24-hour period, while at Speel River 8.86 inches have been recorded. At both Ketchikan and Speel River there has been an average of 50 days per year in which there was one inch or more of precipitation within the 24-hour period, while at Skagway there has been an average of only 4 days. At Little Port Walter, 9.33 inches of precipi- tation have been recorded in a 24-hour period, and at Baranof 3.61 inches. The average num- ber of days per year with one inch or more of precipitation in a 24-hour period has been 77 cB.ys for Little Port Walter and 63 days for Baranof. Even with the large precipitations that occur and even though an automatic recording rain gage has been in operation for several years at Juneau, it is safe to say that rains of southeast- ern Alaska <!o not occur with the extreme inten- sity for short periods of time that frequently characterize the thunder showers of some parts of the United States. Juneau has an average annual precipitation of 83 inches and a maxi- mum total of 5.54 inches in a 24-hour period, yet at no time has the automatic gage at this station recorded over 0. 56 of an inch in one hour. The maximum amount recorded for 10 minutes was only 0.27 of an inch. These amounts are far from excessive and do not compare to some of the heavy downpours for short periods in the state~ and are usually accompanied by thunder storms. The rarity of these phenomena in this part of Alaska no doubt partly accounts for the comparatively moderate and uniform rate of precipitation that prevails in the region. Only 11 tht,nder storms occurred at Juneau during the 21-year period under observation. SUNSHINE The number of days of sunshine is compara- tively low in this region. The data that are available showing the number of rainy days seem to indicate that there is but little difference in the amount of sunshine received in iifferent localities southward from Juneau. In 1944, climatological data show Juneau with 29 days of clear, 49 days partly cloudy, and 288 days cloudy; Ketchikan with 38 days clear, 51 days partly cloudy, and 277 days cloudy; Little Port Walter with 53 days clear, 99 days partly cloudy, 15 It 11150 ~ CLIMATE OF SOUTHEAST ALASI\A ANNUAL VARIATION IN PRECIPITATION IN S.

The record for Radioville is incomplete. Juneau has the longest records concerning sunshine, and for a 21-year period these records showthe average sunshine to be 30 percent of the possible amount. June normally has the greatest amount with an aver- age of 40 percent for the month, and October has the least with only 18 percent. February of 1936 had 15 clear days or 71 percent which is the record for the 21-year period. The lowest percentage on record is 2 percentfor December 1930 with no clear days, one partly cloudy, and 30 cloudy days. To the northward of Juneau the cloudiness decreases a little and permits a corresponding amount of sunshine indicating about 40 percent for Skagway, Haines and Klukwan. By compar- ison, the weather at Seattle has about 25 to 30 percent more sunshine than in southeast Alaska. In general, there are 30 percent more cloudy days in_ the area as a whole and about 45 percent more cloudy days at Juneau than at Seattle. One of the important items of weather and time in connection with any construction in this district is to take advantage of the greatest num,. ber of lair-weather days and the length of the day. The table showing the length of the day from sunrise to sunset indicates that there is sunshine for 14 hours of the day or more at Juneau between April 15 and September 15 of tch year, with as much as 18 hours of sun- Jht during July. The shortest days are during ~cember and January when they rarely exceed hours in length. TULB !I Daylight operations may effect construction >~hedules and costs. Advantage should be taken lf the long summel_' days which permit two 8- lOur shifts. Work canbe carriedon duringthese l shifts without artificial lighting. The sched- lling of work would favor tunneling and localized :onstructionduring the winter a:nd the construe- tion of conduits, penstocks and transmission fa- cilities during the summer. Other weather con- ditions also favor this type of scheduling con- struction operations. EVAPORATION Evaporation as a factor in rainfall has not been studied in connection with its effect on pre- cipitation in the southf!ast Alaska-"' area. Neither the temperature nor relative humidity are con- ducive to large evaporation losses. Nearly all of the stream flow records have been obtained below extensive lake systems. Even iri the case of developing the existing lakes into reservoir storages the surface areas will not be increased to such an extent as to cause evaporation to be of any importance in the development of power projects in southeastern Alaska. SNOWFALL The snowfall in southeastern Alaska is mod- erate in quantity except on the elevated slopes of the mountains. This statement is contrary to the idea prevalent in the United States. The snow- fall is the least in the extreme southern portion of the district, with the mean annual snowfall at Ketchikan only 34.4 inches for the sea level sta- tion. The Annex Creek Station located in the north inland area shows a mean annual snowfall of 239. 3 inches and is the greatest for any sea level station. The greatest recorded mean an- nual snowfall of 448.4 inches occurred at Jumbo Mine at the 1,500 foot elevation. There is no doubtthat there are still greater snowfalls which are normal to other localities at the same or higher elevations but they have not been record- ed. It is possible that the snowfall precipitated over glaciers even at lower elevations may have totals for the year which will exceed the record at Jumbo Mine. It should be noted that at the sea level precipitation stations the water equiv- alent of tM snowfall varies from about 3 percent of the total precipitation at Ketchikan to 33 per- cent of the total at Klukwan, in the extreme north- ern end of the district. _ The accompanying-chart showing the "Aver- age Monthly Snowfall in Inches"· indicates the annual average snowfall to be 34.8 inches for a period of 16 years at Skagway; 107.2 inches for a period of 37 y~ars at Juneau; 33.8 inches for a period of 26 years at Ketchikan; and 26.1 inches for a period of 9 years at Sitka. · In Table 6 the mean t~mperature, the average CLIMATE OF SOUTHEAST ALASKA 25 precipitation in inches, and the average snowfall in inches, unmelted, averaged for the entire number of stations is listed for 38 years from 1907 to 1945. The temperature cycle appears to have risen from a mean of 39° during the first 5 years to a mean of 42° during the last 5 years of this 38-year period. The average snow- fall tends to be greater when the mean tempera- ture is in the vicinity of 39° to 400 and less when the temperature tends to be in the vicinity of 41 o to 42°. The normal temperature is 41 ~ the average precipitation 87.45 inches, and the snowfall 97 inches, unmelted. There have been during this period of 38 years, 19 years in which the precipitation, and 14 years in which the snow, have been above normal, with all of the rest below normal. Only in 5 of these years have both the depths of snow and the precipitation been greater than normal in the same year. The effect of the cycle of higher tempera - ture appears to support an observation made in the field and previously mentioned in the report, that the glaciers appear to be receding during this cyclt: ot years. If the glaciers snould dis- appear, then the present regimen of discharge in the streams would change and probably show grea_fer extremes- The winter's snow often disappears at sea level in March or in the early part of April. The first appreciable snowfall of the winter usually occurs in the latterpart of October in the north- ern end of the district, and during November in the southern. In some years an appreciable snowfall occurs in the southern portion after Jan- uary and also there are many instances when the first snow 34.8 16 yrs. 20 I=R=R==R=R==R lO 107 . .2 37 yr$. AVERAGE MONTHLY SNOWFALL of winter has not appeared in that section until December. Owing to the fact that rains may and usually do occur at any time during the winter, the snow seldom accumulates "" "' 15 ~ 10 0 J FMAMJJASOM D J:I'"MAMJJASONO CHART 3 .. .. ~15 10 SOUTHEAST ALASKA SCAI.E OF MII.ES so 0 so 100 to any great depth at the sea lever stations. In fact, there have been several winters in which 6 inches was the great- est depth of snow on the ground at any time in Ketchikan, Sitka and Skagway, and 12 inches the greatestdepth at]uneau. Dur .. ing the unusually warm winter of 1925-1926, the greatest depth on the ground at the com- munities mentioned was con- siderably less than the figures mentioned above. It should be understood though that these figures apply only to the im- mediate vicinity of the respec- tive stations. The snow depths on the attjacent mountain slopes are considerably greater. The snow remains on the slopes and in the timber for longer periods in spring andaccumu- lates earlier in the autumn than at sea level.

The annual ranges in temperature are small. The difference between the mean temperatures of the warmest and cold- est months at Sitka are 240; at Juneau 290; at Ketchikan 260; at Skagway 390; and at Klukwan 46°. In contrast to these moderate ranges may be cited the annual range of 60° between the Jan- uary and July means at St. Paul, Minnesota. A record of 46 years at Juneau shows the mean temperature to be 42.2°; for the period of 10 years at Ketchikan to be 46.40; and at Sitka to be 44.00. Such stations as View Cove, Tree Point and Hydaburg, all with comparatively short records, show slightly higher mean temperatures than Ketchikan. The mean temperatures of Sit- ka and Ketchikan are about the same as those at St. Paul, Minnesota, and Halifax, Nova Scotia, while the mean temperature at Skagway nearly coincides with Bismark, North Dakota, and Quebec. Many people envision Alaska as a land cov- ered with ice and snow, and in a perpetual frigid temperature, but this is hardly the case, as the mean temperature for the month of January at Sitka is 0.5° higher than the mean for the same month at St. Louis, Missouri, and 4.00 higher than the mean at Boston, Massachusetts. The mean temperatures for the month of January for all the stations in the district, except for those in the extreme northern portion, are higher than the January mean at Chicago, lllinois. Zero temperatures occur very rarely except in the extreme northern end of the district, and there have been winters when there were none recorded at the sea level stations from Juneau southward. Temperatures of zero or lower have occurred only on 65 days in a period of 39 years recorded at Juneau, on 13 days in 24 years at Ketchikan, and on 16 days in 3'7 years at Sitka. However, in the extreme northern portion of the district, zero temperatures have occurred on an average of 40 days each winter at Klukwan, and 52 days each winter at Porcupine Creek. The lowest temperature recorded in the district is -420 at Porcupine Creek. The lowest reading in 51 years at Sitka is -5°, The number of days with a minimum tempera- ture of 32° F., or lower, are 107 at Juneau, 75 at Ketchikan, and 103 at Sitka. The temperature remains above freezing for 4 months at Juneau, for 5 months at Ketchikan, and for 3 months at Sitka. In the spring, the date of the last freezing temperaturefrom Juneau southward ranges from April 14 to May 31, depending upon the exposure and the immediate topography of the station, while in autumn the date of the first freezing temperature ranges from September 1'7 to Nov- ember 2. In the northern end of the district these comparative dates range from May 27 to June 2 in the spring, and September 10 to Septem- ber 18 in the autumn for the Skagway and Klukwan stations. Freezing temperatures are virtually unknownin the southernthree-fourths ofthe dis- trict during June, July and August, and even in the northern fourth they occur only occasionally CLIMATE OF SOUTHEAST ALASKA 27 near the beginning and end of the 92-day period. Temperatures of 700 or above usually occur at nearly all stations a number of times during each summer, but the cooling effect of the Pa- cific Ocean and the tidewater channels and straits act to prevent the warming of the air to the extent which is experienced during the sum- mer in the interior valleys of the Territory. The stations which are some distance removed from tidewater have the greatest number •of warm days such as Fortmann Hatchery and Klukwan with an average of 39 per year showing readings of 700 or higher. WINDS Wind velocity records have been taken at Juneau since 1917 and at Ketchikan since 1935. During the war other stations were installed but the data have not been made available. However, it is felt that the 1940 published record for Juneau is typical. The station at Juneau is situ- ated at the base of the mountain, and therefore the force and direction of the wind is modified by the local topography, and should not be con- sidered truly representative for all conditions and other parts of the district. The statement compiled by H. J. Thompson, Meteorologist at Juneau, indicates that the aver- age hourly wind velocity by months is 7.2 miles for the year 1940. The average hourly winds by months·range from 5.0 to 8.0 miles overa peri- od of 24 years. The maximum velocities for each month range from 24 to 37 miles per hour. The prevailing direction is southerly. The winter months are the windiest begin- mng with November, and the period of least wind is for the months of July and August. While winds of light to moderate force are the rule, hurricane velocities sometimes prevail in and at the entrances of mountain passes and fiords. This latter is especially true of those winds from the northeastward from tbe . coast range , and notable among these are Taku Inlet and Stikine River. The winds which move through these fiords are usually caused by a steep pres- sure gradient lying between northwestern Cana- da and the eastern portion of the Gulf of Alaska. Under such a distribution of pressure a sus- tained velocity of 50 miles an hour for a period of five minutes was recorded at Juneau in Feb- ruary 1923, with an extreme velocity of 70 miles per hour. Lynn Canal is also noted for its strong Winds from a northerly quarter under similar con- ditions of pressure. Occasionally an area of high pressure over the north Pacific States and a pronounced low pressure over the central and western portion of the Gulf of Alaska will prod- uce strong south and southeast winds and gales which move northward through the inland water- ways which form troughs in a north and south direction. This is especially true of Chatham Strait, the Lynn Canal, and along the west coast of the district. The direction of the prevailing or seasonal wjnds combined with the physiography, control precipitation. The warm, moisture-laden winds of the North Pacific, on reaching the western coast of southeast Alaska are forced to rise in order to go over the great mountain barriers and give up their moisture. This precipitation not only produces a remarkable forest but can be harnessed to produce perpetual hydro electric energy. ....

Table 7 has been prepared showing these ranges covering a few stations, which will be very helpful to those who plan to carry on the work of exploration or con- struction within the area. TABLE 7.

If we assume the earth to be covered with water at a unJform depth, and the moon by the law of gravitation to be exerting an attraction for both the water, and the solid or more inflexible part of the earth, we would have an ideal mathematical problem. However, when the moon is over any point of the earth, its attraction for the water under it is greater than its attraction for the solid earth. Under this condition the moon will tend to pull the water away from the earth and thus cause high water immediately beneath it. Likewise, the moon's attraction for the solid earth is greater than its attraction for the water on the opposite side of the earth from the moon. It tends there- fore to draw the earth away from the water and bring about high water on the opposite side. The moon therefore, as it travels around the earth, causes in general two high waters at a single place each day, one at the upper and one at the lower transit, with two low waters in between. While these conditions are not exactly true in Nature, it helps to make clear the illustration. Actually, the earth, spinning around each day, continually presents different bodies of water and solid earth to the forces of the moon, and at the same time the moon is traveling once a month around the earth. This causes a con- tinuous change in the time element of high and low tides. The moon revolves around the earth from west to east in a little less than 27 days and 8 hours. This illustration is slightly untrue to Nature, in that high water does not actually follow directly under the moon but has a lag, due to viscosity of water, to friction and to land masses. In addition, the tidal forces exerted by the moon and sun are tangential and not vertical. Therefore, the direct lifting power of the moon and the sun is slight, and the water is drawn together from the two sides of the earth under- neath these bodies but always lagging. SPRING TIDES The sun also exerts forces upon the water and solid earth. When the moon and sun are in line relative to the earth, then tidal forces act through gravity on the earth and oceans in con- cert, and bring about the large tides which are "spring tides." If the moon is on the opposite side of the earth from the sun, the tidal forces of both bodies are again in unison and produce the spring tides which occurred two weeks be- fore at the time of new moon; and also the moon's two high waters, one on each side of the earth, combine with the two high waters, which are brought about by the tidal forces of the sun. If the tidal forces exerted by the sun are at right angles to those exerted by the moon and there- 30 WATER POWERS OF SOUTHEAST ALASKA fore are working against each other, each force tending to minimize the force of the other body, then these counter forces naturally will give rise to small range tides called "neap tides." These neap tides occur again in about two weeks when the moon has come t0 its first quarter on the opposite side of the earth relative to the sun. When the moon is in a position closest to the earth, its tidal forces are the strongest, and it is known as "perigee"; and, conversely, its position farthest from the earth is known as "apogee." Variations in the range of tide are likewise brought about by varying distances of the earth from the sun due to its elliptical orbit. When the spring tides occur at the same time that the moon is in perigee, the range of the tide at some places is increased as much as 40 per- cent. Similarly, when the neap tides occur at the same. time that the moon is in apogee, the range is less than the mean by about 40 per cent. SEICHES A study, made by R. A. Harris, a mathe ~ matician of the U. S. Coast and Geodetic Survey covering different types of tides and the behavior of tides in different parts of the world, played a large part in the conception and in the develop~ ment of the latest tidal theory. The idea advanced by previous theories, namely, a single world phenomenon, substitutes regional oscillatory areas as the origin of the dominant tides of the various oceans. These oscillations are set up and maintained by the periodic tidal forces of the moon and sun. To cause an oscillation to continue, it is only necessary to continue the disturbing force. If this force is applied at reg- ular intervals coinciding with the period of os- cillation, the maximum effect will be obtained. Similar oscillations occur in most lakes in which the whole body of water swings back and forth with a period of from 10 minutes to 1 hour and with a range of several inches. These oscilla- tions are known as "seiches" and are caused by sudden changes in atmospheric pressure or by winds over the lakes. Seiches also are developed upon a river by a large quantity of water sudden- ly emptied into the river, or by the releasing of water from a reservoir, and these waves or seiches can be traced by time intervals from the source to the mouth of the river. It is this seiche which frequently interferes with the operations of vessels upon navigable rivers. This wave if produced by a tide may rise ex· ceptionally high as in the Bay of Fundy where at the mouth the range is 6 to 10 feet. It increases half way up the bay to about 20 feet and finally reaches 40 feet at the head of the bay. At An- chorage, Alaska there is a difference of 32 feet or more in tidal range. This means that tide predictions and tables are of great importance in such areas. In fact, all along the shore line or bays, inlets and straits of southeast Alaska, the tide predictions are important to the mariner. VALUE OF TIDAL RANGE In the days of shallow-draft vessels advance knowledge of the state of the tides was of little importance, but as the draft of vessels approached a depth of water over bars and in harbors, such knowledge became of great importance to the navigator. The tide range table has also become valuable to the engineer in the placing of bridge spans, wharfs, structures along the sea side} and to electric power plants located at eea level; to watering places for the convenience of bathers; to the fisherman in planning his fishing trip; and to many other diverse interests. Where the tide range is great as in Alaska, its prediction is im- portant for all kinds of operations from landing cargo to construction and development of power at sea level. At some future time it may be im- portant to consider tidal development of estuaries for power purposes along the Alaskan coast, but for the present needs it seems quite remote. TIDAL DATUM PLANE The necessity of establishing a sea-level datum plane for the engineer is important in all power developments, especially those in south- eastern Alaska. This plane is developed by the study of the tides. Mean sea level may be de- fined as that level about which the tides oscil- late. Since no fixed plane exists in Nature, it is necessary to devise some means for determining and for giving concrete value to this plane, above and below which the tide oscillates. The only means for making this determination is by ob- servations of the rise and fall of the tide. The longer the series of observations the greater the degree of accuracy. The purpose for which it is to be used governs the length of the series, and therefore the accuracy, for the determination of any tidal plane. For practical purposes, a tidal plane obtained from a month of observations may be considered as being fairly well determined. Planes deter- mined at different times, however, may differ TIDES OF SOUTHEAST ALASKA 31 considerably because of long period tides or sea- sonal changes, and differences of atmospheric pressure from month to month or year to year. These conditions make it necessary to have long continued observations at primary stations for general tide control. The determiration of mean TIDE STATION AT ANCUORA.G£. ALASMA Low water Readlnq. 7. 5 Feet 32 \VATER PO\VERS OF SOUTHEAST ALASKA sea level is not altogether a simple matter, nor can it be obtained by a short series of observa- tions. Frequently variations from month to month are as much as 1. 5 feet. Seasonal varia- tions show planes much higher in summer than in winter. TIDAL POWER HEAD In this report, the power houses of several of the projects are placed at sea level or at the head of a bay or inlet in such a way as to permit the turbines to take full advantage of the mean tidal head. This may add from 5 to 8 feet to the mean head at the power plant taken above mean high tide. This, it is obvious, is worth taking advantage of in many cases. These insta!\CeS al·e usually mentioned in each project report. Further investigation in the field might reveal that some p:ojects in which the mean tidal head is not mentioned might bring to light its useful- ness. The table shows the station locations and the diurnal differences between low and high tide. It is felt that this table will bring out the value of considering the tidal head obtainable to any- one who intends to construct a power project under the conditions mentioned in southeast Alaska, Tidal information is also of great value where docks and wharfs have to be constructed, and where estuaries, salt chucks, and sand bars an: iavolved which may affect either navigation or a power development of which the energy out- put may be increased several percent. .. ~ t t:f.l .. , • ·( .· ··" " ~ _. ; ~-·· ·. -~~':...,-' ·! ... , .• ,,~11 ..

TION AND STORAGE 33 RUN-OFF, REGULATION AND STORAGE STREAM .RUN-OFF During the period from 1911 to 1945 there was installed a total of 51 gaging stations for the purpose of measuring stream flow in 47 water- sheds. The maintenance, operation and record- ing of the data at these stations, however, ha~ been spasmodic and non-continuous. The inter- mittent readings in case they were staff gages have made the data of limited value. Only 2 of these stations have a series of data 25 years in length. The records range from a few months to 29 years. The other stations show very lim- itedamounts of data as shown in the accompany- ing table and in the tables in Part VL However, tempered with engineering judgment and an ex- tensive first-hand knowledge of the conditions in southeastern Alaska, Mr. R. R. Rowe has made analyses of the run-off in not only these 47 watersheds in which some run-off data have been recorded, but he has also thrown ccnsider- able light upon the run-off in 150 additional watersheds. With these records, the isohyetal map, the mean discharge, a few miscellaneous discharge measurements and regulation factors, fair estimates of run-off have been conserva- tively assigned to the watersheds, which may be used until improved data can be obtained. These estimates of flow are based on prudent studies of the apparent relationships between Q) run- off and drainage area, and CU run-off and pre- cipitation. Table 8 showing the average annual discharge · in cubic feet per second per square mile shows that during this period of years, 51 gaging sta- tions w~re established. The records of 40 of these stations are of sufficient length to justify some computation of the unit run-off, which is the ratio between the mean discharge in cubic feet per second and the drainage area in square miles; These calculations are found in Part VI ''Gaging Stations and Discharge Records.'' The averages in this table show a range from 8.5 to 19.1 cubic feet per second per square mile, not including the discharge from Crystar Lake which 'represents only the measured waste flow at the outlet. At this point the reader should be re- minded that all calculations and studies are based on data takenpriorto1938.as the report had tore- main unpublished during the intervening period. Some of the more recent data concerning flow discharge at a few of the stations have been in- eluded through 1945 since they were available from 1938 through 1945 but are not included in the studies. If these averages of 8.5 to 19.1 cubic feet per second were considered the mini- mum and maximum extreme for the area, the median would be 13.8 cubic feet per second and could have been taken fOI' all other watersheds with a maximum error of less than 39 percent. The isohyetal map in Part D shows these gaging stations are located between the isohyetes 70 and 150 inches taken at sea level, while it can be observed that nearly all of the power project sites are scattered through the range, between the 30 and 180 isohyetes. If precipitation re- cords had not been available, fair estimates of the flow could have been computed from the known unit run-off records alone, and almost all of'these estimates would have been within 10 to 15 percent of reality. However. large per- centage errors would have appeared in this com- putation in the Skagway area and along both sides of the Chatham Strait. Another important analysis maybe observed in Table 2 "Run-off Compared to Sea Level Precipitation", in Part D. The ratios are non- dimensional and are expressed in percent. In this table there are 31 watersheds showing run- off in inches compared to the precipitation in inches taken at 14 sea-level stations. The re- sultant ratios range from 143 to 205 percent for glacier-fed streams, to 117 to 201 percent for non-glacier-fed streams. By using the percent- age medians of 174 and 159, respectively, of these two sets of ratios, a method is afforded by which the flow from 35 other precipitation sta- tions can be calculated. If the measured ranges were actual extremes, maximum errors for the two types of watersheds would have been 18 and 26 percent, respectively. This is much less than the apparent maximum error of 39 percent for the first ratio previously mentioned. It was not intended that these medians either should or could be used empirically or universally. A knowledge of the particular character of a wa- tershed affords ample opportunity to vary the determinant judiciously. There are areas vary- ing in proximity to gaging stations, or to the precipitation· stations, so that first one and then another base determinant.·· seemed of greater value. Mr. R. R. Rowe who has an extensive first-hand knowledge of this area was able to use his judgment freely in the selection of a base determinant, and in applying variance factors to •.. 1 2 l 5 6 1 • 9 10 - ll 12 :z 15 16 17 •• 19 .., a ... z 25 .. 21 at 29 "' ,, " ~ " ,. )7 ,. a 41 loll lf l6 44 Ill .. ,. !10 " . ...._ . ~a,tt.auat~t aa:: :1•••• Plfb Cr•Mr ...... ~ 5.00 lovl' (Jl••i• u .... 00.00 0.Th ll't'V 15~00.• WlntaalJ es-.. lt .,*» ._.'bn'l Cre&ll UI,OO ra;;.;_; cr ... 20.00 .• lbelw-tr..t 1.1.QO TJN CI-Mit .... .... 1111 CPMII:• fi.OI> C••"~~"• cr•• 2l.lol> r--------- lprao.CI'eek •• 50 .... t.botut hll• 27.00 t ... e Lak• n.u> lp•d 11wn 21.4.00 L-al.M• l1.90 LoG& 11 .. r n.m CNh-rCf"Mit• n~90 hnttl9' CJ'.O• 14.CO t ...... cr .. sa.oo -· ....

In connection with determining the flow at the more important power sites, his deductions are explained in some detail, whereas at the minor power sites his estimates are usually expressed without explanation. Throughout his analysis he has used the criteria ol. estimating reality when- ever the basis was reliable, and to be conserva- tive whenever the basis appeared to be untrust- worthy. In this manner Mr. R. R. Rowe was able to determine the mean discharge for nearly every watershed with some degree of value when- ever more exact data were not available. STORAGE REGULATION Having determined the mean discharge, itis nearly as important to determine the character of the departure from the mean, especially is this so in so far as it may determine the possible regulation of the di~charge during the year. To satisfy this purpose a Storage Regulation Chart 4 was prepared. It shows for those streams with the longer period ol. gaging station records, the relation between the reservoir capacity and the regulated discharge. The reservoir capacity is plotted as abscissae in percent of mean annual run-ol.f, while the regulated discharge, obtained from the coordinate capacity, is plotted as ordi- nates in percent ol. mean discharge. This may be expressed in another way as follows: If the storage is provided equal to "abscissa" percent of mean annual run-off, then the flow regulated by that storage is "ordinate, percent of mean flow, or the stream is "ordinate" percent regu- lated. This chart is a non -dimensional comparison d. regulation characteristics of the several wa- tersheds named in the legend. It is indeoewient c:l drainage areas, total preclpitatiog. total con- tribution from glaciers, and size of reservoirs. 36 WATER PO\VERS OF SOUTHEAST ALASKA ! However, the shape and position of various curves in the groups do reflect (1) diversity of water- shed, <2> natural storage and (3) regimen of pre- cipitation. To illustrate, the curves number 3, 4, 5, 6 and 10 lie in a comparatively narrow band and indicate tha.t a relatively large storage ca- pacity is required. All of these streams are glacier-fed and 4 of them receive most of their flow from high lakes. These 4 curves indicate that there is a greater departure of the annual run-off from normal run-off, as peak years re- quire concurrence of warm summers with heavy precipitation. At the other extreme of storage capacity requirements are streams with elaborate lake systems alfording natural regulation and are located in the southern part of the region where the annual precipitation departs less from nor- mal than in the northern part. If the mean run-off of another watershed has been determined, with the use of a short petiod of records or estimates, and if the watershed res~mbles one of those characterized by the chart, then an estimate can be made of the per- centage regulation obtainable from the estimated available storage. The greater the resemblance to the curve the closer will be the precision; how- ever, the determination of regulated flow will probably be less preci3e than the estimate of the mean flow. It is worthwhile to note the general slope of the curves on the chart which indicate more than 90 perc~::t regulation of the discharge. If a cer- tain storage capacity will regulate 90 percent of the mean flow, then it should be pointed out that it will require about twice this capacity to regu- late the entire mean flow. Mr. R. R Rowe points out thatto obtain this extra 10 perce11t of primary power, will seldom justify the required additional height of dam. Possibly this would have a differ- ent aspect if in some cases the development can take place on a river basin basis, or a group of projects, rather than as a single project. The Manzanita and Ella Creek projects will serve as an illustration of this point. On the other hand if a fue1-power standby is a necessity to insure the load against an outage of the hydropower, then it might prove to be good economy to operate the standby plant a few months every 5 or more years during the low-water periods. However, if storage capacity is developed on the basis of tunneling into a deep lake, the extra cost involved in tunneling still deeper in order to increase the usable capacity is often slight --usu- ally requiring only a longer tunnel, and these additional costs are sometimes partially com- pensated for by a shorter penstock requirement. In many of the earlier estimates on storage capacity, it has been assumed that the storage equivalent to the mean flow for 150 days would alford complete regulation of a stream. The chart, however, indicates that the extremes of this group will require 115 to 355 days and is illustrated by Perseverance Creek and Dorothy Creek, respectively. The discharge records for these streams cover a shorter period than al- most all of the others which lie within the range of 160 to 305 days. Based onthese charts, a 150 day storage capacity should regulate from 58 to 96 percent of the mean flow. The primary and nominal flow are not carefully evaluated in these records. This is due to the fact that many esti- mates were required especially for the winter months, as inaccessibility and ice conditions pre- vented proper observation for making the records, therefore the precise value of the estimates would be low. The primary and nominal flow are approximately equal, ranging from 8 to 20 per- cent of the mean flow, depending upon the ratio of the lake area to the drainage area, and upon the proportion of the drainage area which is fro- zen during the entire winter. Almost all of the uses for unregulated power are seasonal and therefore this factor has little significance. In some parts of this region there is a. period of low flow in the late summer, and the minimum now during this period will determine the value of the small power developments at the salmon canneries. · STORAGE RESERVOIRS There is abundant rainfall in nearly every project area. This rainfall is well spread over the year, so that there is fairly even discharge from the various streams. However, the finest of the streams will show extremes of minimum and maximum discharge similar to that found in nearly every other river basin. It is necessary to have some storage in nearly every basin other than its natural regimen if the average power is to be continuous. It is also fortunate for this region that so little storage in acre-feet of water is required to even out the natural discharge. There are a series of lakes in some of the basins, which regulate the stream discharge. It hasbeenfrequently pointedout by Mr. R. R. Rowe RUN-OFF, REGULATION AND STORAGE 37 that these lakes can be tapped by tunneling and the draw-down storage capacity will be sufficient to create an even discharge, perhaps not to 100 percent of control, but in many cases to a rather high degree. In many projects it has been point- ed out that advantages will accrue, if both the construction of additional reservoir capacity through the use of dams and also of draw-down tunnels is resorted to. There are a few instances where it is sug- gested that "super-regulation" can be obtained by constructing dams to such heights, as will make it possible to have considerable annual hold over capacity. Such reservoirs can be used to great advantage for firming power when sev- eral projects, taken as a group, are linked to- gether by transmission and occasionally when they can be linked together by tunneling from one to the other. The creation of this additional hold over storage capacity can usually be ob- tained at reasonable costs, and therefore, will prove to be an advantageous method in main- taining potential capacity equivalent to a storage battery in the system. Whenever a project or a group of projects are considered for a power development, some of them should be studied with a view to the creation of "super-regulation" and, therefore, to the maximizing of their power value. It is to be observed that as a general rule, only the lower storage sites, or those relatively close to the sea, have as yet received attention in these early studies. As time and necessity require, more comprehensive studies will be undertaken of other possible storages and espe- cially as such potential possibilities are brought to light through air photography, of lakes and reservoir sites on which there are no man-made records. The importance of uniform flow of "glacier-fed" streams has been noted at several points in this report. Glacier ice-fields are a natural water storage of staggering proportions. Prior to the developing of any basin or series of basins, further reconnaissance should be un- dertaken in order to determine before construc- tion that full use will be made of the potential power that might be developed within reasonable limits of cost, necessity and maximization. PART-y POTENTIAL WATER POWER PROJECTS POTENTIAL WATER POWER PROJECTS 39 GENERAL CHARACTER OF PROJECTS There are 200 water power projects located in 201 watersheds reported in the following pages. Nearly all of these projects are treated as individual projects rather than as basin developments. This is a logical approach be- cause the basins are relatively small in extent since only a part of the region is surveyed for water power, and many of the upper portions of these watersheds have not been explored. In terms of maximizing the potential power de- velopments in the basins only a few have been studied. The outstanding exception is the pro- posed development of the Manzanita Creek and Ella Creek watersheds combined into one proj- ect. In contrast to the proposed Manzanita Creek, and Ella Creek developments are se¥eral small projects which can be considered complete, as very little additional power could possibly be created in them, within reasonable costs. Under some circumstances power is necessary even at high costs, but in this highly favorable power development terrain, one does not usually have to look far for an excellent opportunity to make a good selection. There is, however, much field work and study still necessary before the ultimate selections, maximization, and pro- graming of construction can take place, and be- fore the best developments can be fully realized. As previously mentioned the simplest way to present the data concerning each basin is to treat them as individual projects. Some of these basin projects have only one structure, dam, tunnel, conduit or power house, to make them fully operative, whereas others have several structures, tunnels, conduits and power houses. Some involve the transfer of water from one basin to another. Frequently the project at hand has only the lowest 2 or 3 hundred feet of fall in the creek under consideration, and it may make use of only a single lake located relatively close to tidewater. Further investigation may uncover other projects further up the basin which are worthy of as much consideration as those which have been selected for this report. Such worthy projects cannot be reported at this time, how- ever, since the data are both meagre and of doubtful value. It is almost axiomatic that as time and opportunity permit important data will continue to be made available. GROWTH OF INSTALLED CAPACITY There has been an expansion in the use of power in southeast Alaska over a period of 40 years as shown in Table 9, which gives the in- stalledcapacity during specific periods of years. Prior to 1900 a total of 6,000 horsepower was installed, and by 1942 this had increased to 28,629 horsepower. Other increases during the Second World War have not been made available for publication. The most rapid expansion in facilities for the generation of power took place between 1909 and 1916, these 8 years accounting for 75 percent of the present installed power capacity. TABLJI 9.

S. G. S. Water Supply Papers. Hoyt reported in Paper 372, page 167, a total of 15,319 horsepower as of 1908; Canfield reported in Paper 692, page 43, a total of 37,350 horse- power as ·of 1919; and Henshaw reported in Paper 836, page 155, a total of 32,965 horse- power as of 1930. All of the estimates were based on rated capacities but Henshaw used onlytbose plants ratinglOO horsepower or over. LOCATION OF PROJECTS The map and the table which follow attempt to summarize the principal features of project locations and power capacities. The projects listed in the table for presentation are arranged on the map geographically in clockwise rotation beginning at Hyder on the mainland, a com- munity on the shore of Portland Canal in the southeast section of southeast Alaska, and pro- ceeding westward and northward to Skagway. The same clockwise arrangement for locating projects is also used on each of the islands. The water-stage recording stations described ·in Part VI of this r~port are located on the same map in the same clockwise direction. There are only 51 water gaging stations in 47 basins presented as compared to the 200 power projects. • -iO W .-\ TER PO\VERS OF SOUTHEAST :\LASKA Table 10 entitled "Water Power Projects in Southeast Alaska Showing Location and the Potential Capacity in Horsepower," is shown on the following pages. This table summarizes certain pertinent data taken from the descrip- tions of the projects. This table gives the num- ber and name of thP project; the body of water into which the stream or lake outlet discharges; the main body of water at tidewater which is nearest to the point of discharge; the mainland or island location of the stream involved in the project; the number of principal structures in- volved 'in its construction; and the number of generating stations together with the generating capacity in primary and average horsepower. The column in the table referring to the number of dams or structures does not include all of the structures that may be necessary to complete the project, nor does it refer to the particular size or the cost of a project. It simply means that there is at least one struc- ture of importance necessary to make the proj- ect operate, whether it is a reservoir, a dam, a diversion dam, a tunnel, a conduit, or a pen- stock. In the column referring to the number of generating stations are given the number of generating stations proposed in this particular plan of developing the project in order that it may produce the proposed primary and average horsepower. The number of generating sta- tions proposed in these projects may not be ther the final or ultimate number that will be veloped on the project, but from the existing ·nditions at the project site or sites, this mber of generating stations will harness the lling water. There are 228 generating sta- )ns proposed in this group of 200 projects, but :::ven this number falls short of complete devel- opment of all of the projects. The reason for not completely developing a basin project is usuallv stated in the individual project report. POWER COORDINATION The problem of coordinating the power proj- ects geographically scattered as they are from Hyder to Skagway and from Dall Island to Peli- can Cove, spread through this rough and rugged domain studded with thousands of islands and a narrow strip of mainland, all separated by deep channels, is one for the creative genius of many ~ngineers, technicians and scientists all moti- vated by the spirit of carrying out a great en- terprise for the improved .velfare of the nation. POTENTIAL POWER LOAD It is possible to have almost complete coor- dination in the operation of the proposed proj- ects described in this report. Whether it will be necessary or desirable to tie all of the proj- ects in southeast Alaska together with trans- mission will depend upon the demand for power and where that demand load wi11 be located There are no industries of size to use a large quantity of power at present in southeast Alaska. The population is very sparse. There are po- tentially important resources of fishing, mining, lumber and pulpwood The fishing . industry appears to be well established Mining has been principally applied to gold production. The mining industry presages the possibility of a metallurgical industry, and the lumbering industry means dressed lumber and plywood, while the pulpwood industry will bring paper making and the wood chemical industries. If these industries are established, and there is a need for establishing them, population will mi- grate toward these industries and communities will be established, all of which taken together will increase the demand for electric energy many fold. The establishment of a back-bone source of power is a prime requisite in the prop- er exploitation and conservation of these re- sources, which at present lie idle and are tend- ing to waste away with age and the lack of sufficient husbandry. AREA OF LAND IN PROJECTS Only slightly more than 10 percent of the total area of southeast Alaska has as yet been involved in the projects listed in this report. Table 11 entitled "Relation of Project Areas to Land Areas in Square Miles and in Percent," shows the name of the island; the area of the land; the areas of the watersheds in square miles involved in the projects; the ratio in per- cent of the land in each group of projects on the island or mainland as related to the total area in each island or mainland; and the ratio in per-< cent of the land area in the group of projects on the island, or mainland, as related to the total area involved in all of the projects. There are 18 islands and the mainland in- volved in one or more of the 200 projects des- cribed in this report.

These 2 islands are Sukkwan and Etolin. Tuxe- .~ kan, Douglas and Admiralty islands have had from 15 to 20 percent of their areas studied for potential power development, while Annette, Revillagigedo and Baranof have had approxi- mately 30 percent each. There are six islands which have less than 1.5 percent of their areas included in these projects. This means that there remains an opportunity to find considerable potential power in the streams which as yet have not been surveyed or reported upon. It certainly seems reasonable that there should be found several times as much potential power as has been reported in the streams and basins ad- jacent to those which have been described in r•this report. A partial study indicates that more than 80 percent of a watershed is usually included in ""'"the useful part of a project. This would seem to mean that nearly 80 percent of the entire land area can become useful in some potential power project. This might prove to oe true, but it is felt that many basins with glaciers which either tend to reach or do reach the sea and which con- trol much of the potential power area make it -··necessary to discount some of this potential Land area for power purposes. However, it is reasonable to assume tbat at least haU of the land area can be made available for power de- ·-;,relopr:rtent. Therefore, it is felt there may be at least 3 to 4 times the amount of potential power still unreported other than that which is included in this report. It should also be mentioned that there is con- siderable power to be found in the Taku and Stikine Rivers in British Columbia. These riv- ers are practically at sea level when they cross the international boundary into southeast Alaska. From these crossing points they rise rapidly into the interior. This means that they have considerable fall as well as large gathering areas with many of their tributaries fed by the glaciers and ice-fields which exist along the eastern slopes of the principal ridges which mark the boundary. It is estimated that there are 1,500,000 kilowatts of firm capacity in the Taku River basin and 4,000,000 kilowatts in the Stikine River. These are sizable blocks of pow- er which may eventually be linked with some of the developments which may t>Et,.undertaken on the mainland and the island areas of southeast Alaska. With this potential capacity of power both in and near southeast Alaska, its proper and useful economic development is assured at reasonable costs. POTENTIAL POWER OF PROJECTS In this group of 200 projects there are 7 in which the power capacity is not known, but they appearto be relatively small from the available data. There are 51 projects, or 25 percent, having less than 1,000 average horsepower; 74 projects, or 37 percent having from 1,000 to less than 3,500average horsepower; 48 projects, or 24 percent having from 3,500 to less than 10,000 average horsepower; and 27 projects, or 14 percent having from 10,000 to 51,000 aver- age horsepower. There is one project which has 38,000 primary and 51,000 average horse- power, while there are 6 projects which have an average of less than 100 horsepower. The group of 27 projects having over 10,000 average horsepower capacity total 447,990 pri- mary and 534,530 average horsepower. This is more than half of the total capacity of the 200 projects showing a total of 789,860 primary and 1,008,370 average horsepower. The group of 48 projects ranging from 3,500 to 10,000 aver- age horsepower has a total of 290,430 average horsepower. The group of 74 projects ranging from 1,000 to 3,500 average horsepower has a total of 154,660 average horsepower. The re- maining group of 51 projects ranging below 1,000 46 WATER PO\VERS OF SOUTHEAST ALASKA ave rage horsepower has a total of 28,750 aver- age horsepower. The largest 75 projects have a total of 824,960 average horsepower, or 82 per- cent of the average capacity of the 200 projects. It is important to note that of the 27 proje~ts of 10,000 average horsepower capacity and over, 16 of them have primary horsepower practically equal to the average horsepower. The total primary power for the 27 projects is 447,990 horsepower, or 84 percent of the 534,530 average horsepower. Jt is obvious that the average power can be completely firmed. During the past half century there have been power developments at, or near 51 of the 200 proposed projects. At least 10 of these proj- ects have been abandoned or dismantled and of the remaining 41 projects only 8 were of suffi- cient size as to approach the average horse- power capacity of the proposed site develop- ments, and 19 projects as installed were of 100 horsepower capacity or less. The improve- ments to the existing projects, or the recorded data concerning new projects which may have been constructed during the intervening period from 1938 "" 1945 are not immediately avail- able except in the case of Pelican Cove Creek for which a license was issued in 1942. The improvements which took place were principa.ly for use in connection with the armed forces and up to the present time are not officially re- ported for the purposes of publication. EFFECTIVE HEAD The analysis of the effective head of water at the various generating stations shows a range from 18 to 2,345 feet. There are 24 projects or 11 percent, which have less than 100 feet of effective head, and 19 projects, or 9 percent, which have over 1,000 feet of head. There are about 59 percent of the effective heads which range from 100 to 500feet, and 20 percent which range from 500 to 1,000 feet. In restating, there are approximately 80 percent of the effec- tive heads which range from 100 to 1,000 feet, and about half of these range from 100 to 400 feet. This indicates, relatively speaking, that only about 10 percent of the projects may be classified as low-head plants, about half of them as medium-h,ad plants, and the remain- ing 40 percent as high-head plants. MEAN DISCHARGE The analysis of the mean discharge of these watersheds, at the proposed sites, shows a range from 2 to 2,260 cubic feet per second. In terms of power sites 37 percent of the projects have discharges of less than 10 cubic feet per second, 54 percent of the projects have less than 50 cubic feet per second, while 35 percent of the projects range from 100 to less than 300 cubic feet per second. There are 22 sites which range from an average. discharge of 300 to 2,200 cubic feet per second with 14 of these projects ranging from 300 to less than 600 cubic feet per second. The Speel River project shows the greatest mean discharge of all of the projects, having a discharge of 2,260 cubic feet per sec- ond, combined with a head of 250 feet, which develops a capacity of 36,000primary and 51,000 average horsepC'wer. Dorothy Lake with a mean discharge of 107 cubic feet per second, a head of 2,345 feet and coupled with another mean discharge of 35 cubic feet per second, a head of 860 feet in the same watershed, shows a combined power output of 25,600 primary and average horsepower. COORDINATION OF POWER BY AH.EAS AND GROUPS The map showing the location of these proj- ects helps to simplify the overall picture. Thus far the survey shows there are 3 general areas, Ketchikan, Juneau and Sitka, around which are grouped the projects as indicated in the table. Each area is subdivided into groups, which ap- pear to be capable of geographically being con- nected together by transmission. The selection and order of assembling the projects is not for the purpose of laying down any hard and fast rule with regard to their grouping, but rather to focus attention upon their potentialities. There are several projects in these groups which would scarcely pay the cost for harnessing them for power, since due to their small size and the transmission necessary to connect them to the load center, or to the interconnecting substa- tion which acts as the gathering point, are lo- catedatdistanceswhich appearto make the pow- er expensive. Especially is this true if there is only one small station constructed too far from the general transmission route. Usually there are several other projects which could be tied in on the same line. There are undoubtedly many other potential projects still unsurveyed which would add power to the same transmission POTENTIAL WATER POWER PROJECTS 47 line along its route to the same load center. Under these conditions the transmission cost per project may become low and the projects profitable. In Table 12 entitled "Water Power of South- east Alaska Showing Projects Geographically Grouped with Capacity in Horsepower" and in Table 13 entitled "Water Power of Southeast Alaska by Areas and Groups in Primary and Average Horsepower" are grouped the projects by areas in such a way as to lend themselves to reasonable transmission ties. There are a few exceptions to such a coordinated plan as explained in the preceding paragraph. Practically all of the projects of each area lie within an 80 mile radius of these 3 adopted load centers. This does not mean that the TABLE 12.

The principal load centers will be located where- ever the heavy industries are established. The exception is the "North of Stikine River Group" which is statistically assembled with the groups making up the "Juneau Area". This "North Stikine River Groupn is approximately 100 miles south of Juneau and 150 miles north of Ketchikan. This particular area has thus far received only partial investigation in the field survey~ but its 63,600 average horsepower is indicative that this area could well be the be· ginning of another block oi power comparable with the Ketchikan and Juneau areas. KETCHIKAN AREA The Ketchikan area has 205,000 average horsepower within a radius of 40 miles, or over half of the average power included in the area. If a transmission line 25 miles long is added in a northerly direction from Revillagigedo Island to tie in tlie "Bradfield Canal Group" with its 107,000 average horsepower, it will raise this amount to 312,000 average horsepower, which is three-fourths of the 402,000 average horsepow- er included in the Ketchikan area which can be made available for the proposed load center or centers. JUNEAU AREA The "Juneau Area" has 196,000 average horsepower within a radius of 40 miles or slightly less than half of the average power in· eluded in the area. There are 256,000 primary and 348,000 average horsepower within a radius of 50 miles out of a total of 316,000 primary and 418,000 average horsepower listed for the area. A transmission tie line of 60 miles ex· tending southward from Port Snettisham will interconnect the 64,000 average horsepower in the "North Stikine River Group". This latter, added to the 348,000 average horsepower, makes the total nearly equal to the statistically sum- marized group oi projects ineluded in the "Jun- eau Area". SITKA AREA In the "Sitka Area" the principal group of power projects surveyed are on Baranof Is· land. However, in the table are included the projects on Chichagof, Kuiu, Kupreanof and Kruzof Islands. The "Sitka Area" table shows a total of 160,000 primary and 188,000 average horsepower. If a 50 mile radius is drawn about the "Sitka Area" a part of Baranof, Chichagof, Kuiu, Kupreanof and Admiralty' Islands will be included, and within this circle there are lo- cated 133,000 primary and 155,000 average horsepower. This analysis shows that within relatively short transmission distances there are approxi- mately 875,000 average horsepower and more than 700,000 of this amount lies within the 50 mile radii of the three load centers of Ketchikan, Juneau and Sitka. The 6 groups on the mainland, consisting of Hyder, Rudyerd Bay, Bradfield Canal, North of Stikine River, South of Taku Inlet, and North of Taku Inlet have approximately 560,000 average horsepower. If the Revillagigedo Island and Baranof Island groups are included with these 6 mainland groups, it will total over 800,000 aver- age horsepower. There are many projects which are con- sidered as river-run plants. This is due to the fact that there is not sufficient storage which can be created to control the discharge at the dam site or above. Also some of the streams and watersheds without storage capacity freeze early and remain frozen for several months. This reduces the discharge and therefore the production of power. Such developments made idle by the forces of nature have to be com- pensated for by other hydro developments in other watersheds which have sufficient storage capacity to carry the system load during the winter season or over a dry period. Therefore some projects are planned with not only suffi- cient storage capacity to even out the discharge from the watershed, but are planned for "super- regulation''. This means that the storage capac- tty is sufficient or should be of sufficient size not only for seasonal hold over, but for annual hold over also. The proper rules for regulating the discharge from these storages will enable these projects to firm the power for those plants which do not have sufficient storage. Careful studies should be carried out to deter- mine how these groups of projects should be operated in order to maximize their usefulness and to determine the maximum storage capac- ities and generating facilities which are needed. The essence of the operations of all of these plants coordinated together is to firm river- run projects with hydro storage projects on 50 WATER PO\VERS OF SOUTHEAST ALASKA both a. seasonal and annual basis. TRANSMISSION The physiography of southeast Alaska pre- sents many problems in the transmission of electric energy from the place where it will be generated to the place where it will be consumed. The problems of construction are difficult but not unsurmountable. Nature has fixed the lo- cation of dam sites and generating plants. Na- ture has also limited the number of sites for the establishment of large communities and major industries. The harbors are invariably pro- tected and deep but the shore line rises abruptly. The shore line and terrain presents nearly as many difficulties for the construction of trans- mission lines as it does for the industrial es- tablishments. If the familiar types of trans- mission power lines used in the states are con- structed, they must pass over high mountains, through dense forests, across steep talus, snow covered ice-fields, moving glaciers and deep canyons. They must withstand sleet, snow, ice, wind, tree falls and rock slides. Long spans, heavy anchors, cliff suspended and channel crossing overhead lines will require ·heavy maintenance costs and the original costs of construction will also be high. These problems can be simpli- fied to some degree by using insulated lead covered cable similar in appearance to the familiar telephone trunk cables.** 'rhe cable a1n the transmission of electric power in large quantity over important distances the use of lead covered three phase cables may have so.e advantages over the open transmission lines usually adopted in the states. The advantages may be sufficient under some circumstances to bring about lower costs for cable installation over that of the usual ae- rial installation. The 1 ead cove red cable has the followin~ char- acteristics: 1. The reactance of the cable is far less than that of the open line and the capacity far greater, with the result that for the se~~e size and the seme length of conductor, the voltage drop will be much less than with the aerial lines. 2. The excessive capacity of the cable may hau- pen, or may be manipulated, to have a far bet- ter full load power factor than that of the open aerial line. In this case, the capacity may be very troublesome to the generator under light loads. can be carried on steel catenaries close to the ground and supported by short poles. Cedar poles can usually be cut close to the route and do not need butt treatment to protect them from decay. Experience has demonstrated that there is so much precipitation that the poles remain almost continuously wet in the summer and fro- zen in the winter, which prevents deterioration. Such lines are easy to maintain, outages are few and the efficiency is improved. Only a narrow path cut through the forest or along the shore line is required. Wind storms would have no effect, and the sleet and ice load through the mountain passes would seldom ever affect the cable operation at any altitude. Cable structure is simple and practically all danger is eliminated to the maintenance crew, and to the forest worker nearby. Armored cables can be easily laid under water across the channels and through the inlets. In fact, so many of the generating plants are located so close to tide- water that it would be entirely reasonable to interconnect them by means of these lead cov- ered cables. The usual depths of the channels are not disadvantageous but on the contrary are advantageous as it assures almost perfect pro- te{:tion. The laying of cable transmission lines in channels, bays, inlets and fiords, is simplic- ity of construction in itself. The method and design are not new, for there are many examples of their use both in this country and abroad. Since many of the generating stations are rela- 3. The lead covered cable is very senst tive to ovet'-heattng and should not be exposed unpro- tected to intense line variations. 4. The aerial lead covered cable may be very readily installed in rough country and with- out the necessity for the expert crew anrl equipment necessary for the installation of high voltage non-covered aerial lines. ~. The 1 ead sheath of the cable is well grounded and therefore protection of a high degree is secured against lightning. 6. The lead cable is usually best suuported by a messenger wire, which when necessary can support very long spans. Such cable is always accessible and faults are easily located. 7. When lead cableisplaced unrler water, faults ere not as eat~ily located for repair. The water, however, is an excellent protection against the over-heating of the cable and also against molestation if installed at favorable depths. There are numerous installations of trans- POTENTIAL WATER POWER PROJECTS 51 tively small in capacity and rather close to- gether, the energy generated can be gathered at selected points from several of these sta- tions at lower voltages and then stepped up to higher voltages for transmission to load centers. By using lower voltages for gathering purposes the cost of transmission in this way would be reduced advantageously. Some of the larger generating stations on the system would be tied in at the higher voltages. Southeast Alaska presents an opportunity to use this method on a large scale and probably with a fair margin of economy as compared to the usual overhead transmission line with a broad right-of-way. Table 14, "Transmission System Connect- ing the Principal Project Stations, shows the estimated distances in miles between stations taken without consideration of terrain or tech- nical conditions involved", is only for the pur- pose of acting as a guide toward an intercon- nected system. The table shows the project number, its group location, the estimated dis- tance in miles between the project at hand and the next project to which it is connected, to- gether with primary and average horsepower. The distance in miles is estimated without con- sidering the roughness of the terrain, length of shore line, the depth of the channel or glaciers and ice-fields. The latter especially may have to be avoided. There are 6 transmission lines which inter- connect projects similarly as a trunk line. The 111isston cables for short distances now in use in this country and there are many examples existing in European countries. d.c<'nrding to a report in "The Electrician•, vage 1,31.!~, issue of May 17, 1946, a cab] e 20 kilo- meters lon,ll; was install·ed between Clichy and St. Denis to operate at ~20 KV. This line has been tn OlJerll.tion for about ten years without trouble, ex- cent for a repair which had to be made after a third party had severely gashed the cable permt tting a leakage of oil. Nevertheless, the cable was cap- able of being operated under voltage until the fault was located. A new cable is to be instftlled shortly which will carry the sup-ply at .2.20 KV into Paris. According to a re-port in "The Uectrician•, page 883, issue of April 3, 1946, by the Brown Boverie Company, a 400 KV transmission line had been planned and the desi~~:n for the equipment to operate it had been on the drafting boards for some time during the war. This line was to be run from transmission system tie line No. 7 is suggested only for the purpose of tying the principal trans- mission line No. 6 of the Baranof Island group with line No. 5 of the Admiralty Island group. Transmission line No. 3 serves in a similar way to tie line No. 2 with line No. 4. It has, however, 2 fairly large projects more or less midway between its outer connections. For the present the load centers are taken at Ketchikan, Juneau and Sitka. In the actual establishment of load centers, this will not be the case. Trans- TABLE 14.

This group includes only 4 projects of less than 5,000 aver- age horsepower along the general route of the principal transmission lines. These principal lines, of course, could be interconnected with nearly all of the other projects, whenever need for the power arises. This presentation of the transmission problem serves to focus attention in a broad way, to the real possibilities which exist in southeast Alaska for the harnessing and bringing together in a useful form the hydro energy nature has so abundantly provided and is now totally wasted and which may be turned into a tremendous asset and provide the back- bone for healthy and much needed industries . WATER POWER PROJECTS PROJECT PATTERN There are 200 projects described in the following pages. They range from less than 100 horsepower to 51,000 horsepower. It was pos- sible to use a general pattern in presenting the data of each project as follows: 1. LOCATION 5. DAM SITE 2. DRAINAGE AREA 6. POWER CAPACITY 3. RUN-OFF 7. REMARKS 4. REGULATION In the "LOCATION" of a project, the lati- POTRNTIAL WATER POWER PROJECTS 53 tude, longitude, and distances from some other salient points are usually referred to. If there are lakes, or other streams in the watershed, they are named, with their area and elevation given if the data are available. Occasionally references to adjacent watersheds are included. The "DRAINAGE AREA'' usually gives the area in square miles draining to the proposed dam site. Sometimes this is amplified by stat- ing the drainage area to the outlet of each lake involved, or the junction of side streams, or it may include the total basin area. References to the adjacent basins are made, especially if a part of it is to be diverted. · "RUN-OFF" is usually estimated as of the dam site or lake outlet and expressed in terms of the mean discharge for the year in cubic feet per second. The maximum and minimum discharges are sometimes given, and occasion- ally the quantity available for continuous power. .The method of arriving at these quantities is from actual gage readings, if they have been taken, or by comparison with some other wa- tershed if they have not been recorded. The ''REGULATION'' of the discharge is usually governed by the amount of storage capacity available in the lakes or at the dam sites. The requirements for complete regu- lation are .stated in acre-feet, and also the quantity which can be developed within reason- able limits of construction costs for a reservoir, or the amount that can be obtained by tapping a natural lake at some determined elevation. The "DAM SITE" will include whatever data are available applying to the structure or group of structures necessary to make the proj- ect operate at a certain capacity. Dams, tun- nels, conduits, penstocks and the location of the power plants are all included under this general heading. The size of the dam, the length of conduit, tunnel or penstock and the conditions under which they can be constructed are stated whenever such data are available. Occasionally more than one plan of development is presented in order to indicate that there is a choice de- pending upon the type of economic accomplish- ment needed. The effective head is estimated in feet. The "POWER CAPf\CITY" is usually stated for the total potential development in terms of primary and average horsepower. The ultimate installation is seldom estimated, unless it ap- pears by reference in some application for a license, and then it is usually found under the side heading of "REMARKS." "REMARKS" includes references and des- criptions of proposed developments found under applications for licenses to the Commission, or in applications, for priorities, if such permits were granted by either the Forest Service or the Department of the Interior. Occasionally descriptions of the existing power developments are given if such have been undertaken even though they may be only a partial development, or have been dismantled or abandoned. DEFINITION OF TERMS For the purpose of making this report clear, certain terms used in the descriptions will be defined. These terms are used in the same sense as the engineers in the field reconnais- sance defined them for their use in connection with the surveys and studies in this report. All are hydraulic terms and are in common usage. Some are not yet standardized, such as "pri- mary capacity," and some like "total capacity" have become obsolete, except for the adminis- tration of old permits which are used to deter- mine the rentals. "NOMJNAL-FLOW" is the least mean dis- charge for two consecutive calendar months taken from a 5-year discharge record. It is the mean nominal-flow for each period of 5 years, when taken from a series of 5-year records. If taken for a series of 5-year records and a shorter period, then it is the weighted mean of the noruinal-flowfor each period, and thP. weights are taken proportional to the length of each period. · "PRIMARY-FLOW" is the mean monthly discharge equaled or exceeded for 90 percent of the months of a continuous record when used in connection with the analysis of flow of unregu- lated streams. "REGULATED-FLOW" is that discharge available umost of the time" after development of, and with foresighted manipulation of certain created storage. "Regulated-flow" implies artificial regulation of a stream unress it is especially noted in the reports to the contrary. This "regulated-flow" has been computed with monthly increments on mass diagrams as the discharge available "all of the time". "Regu- lated-flow, computed in this manner is proba- bly equivalent to that available somewhat more than 90 percent of the time due to variations 54 WATER POWERS OF SOUTHEAST :\LASKA within calendar months and to the short periods of some records. In general, the precision of other data does not warrant better precision in the determination of regulated-flow than the standard adopted here. "COMPLETE-REGULATION" provides suf- ficient storage capacity to make the regulated- flow equal to the mean discharge. "UNDER-REGULATION" provides only suf- ficient storage to regulate a flow less than the mean discharge. n SUPER-REGULATION" provides more storage capacity than the required capacity for "complete-regulation". "Super-regulation" is a part of a plan of development in which it is proposed to combine the output of a project with that of an "under-regulated" project. " MEAN-RESERVOIR" is the arithmetic mean stage of the reservoir in order to obtain constant output at full capacity, It is the weighted mean stage, for varying output when the weights are proportioned to the output. In almost all cases in this report the !(mean- reservoir'' has been taken at a stage equivalent to one-third of the possible draw-down storage capacity; Calculations made for 3 reservoirs indicated this assumption to be very conserva- tive. "MEAN -TIDAL-DRAFT" assumes that ad- vantage can be taken of the vacuum head to tide level, utilizing the head and flow congruent to reaction turbines for power houseslocated at tidewater. This advantage is taken at one-half r the diurnal tidal range. The reason for not :alizing the advantage of the full diurnal range as that in so doing it mignt not lend itself to ::onomy in the design of large draft tubes to be ) constructed as to withstand the vacuum head ccurring at maximum ebbs. It is felt the error involved is negligible in using half the diurnal range. A list of tidal metering stations may be found in Part m. "MEAN-STATIC-HEAD" is the differential elevation between the mean head-water, mean reservoir, mean forebay OJ' division contour, and the mean tail-water below the turbine or the center of the jet at the point of tangency to the impulse wheel. "MEAN-EFFECTIVE-HEAD" is the mean static head less the head lost in the conduit due to friction and surge. The gradient due to fric- tion as taken at about .001 for tunnels, .004 for low pressure pipe, and greater for penstocks. "DATUM" is the plane taken at sea level from which elevations and c;:ontours are referred to and is known as the higher high water plane. These can be referred to mean sea level by adding half the diurnal range or to the mean lower low water by adding the entire diurnal range. This was approximated in each case by comparison rather than by measurement. "UTILIZATION, refers to utilization factor except and unless carrying a base or steady load. It is effected by variation in demand, caus- ing losses of water at spillways, or wasteways, or losses of water and efficiency if nozzles are deflected, or of pressure head due to surges in the penstock or variation in the forebay level. That portion of the theoretica 1 power, cons ide red as unity, remaining after deducting for these losses is callea the utilization factor and will generally equal or exceed the load factor. The utilization factor is sometimes expressed in percent. "TOTAL CAPACITY" is defined in permits as the continued product of the factor 0.08, the nominal flow, the mean effective head and the utilization factor. If regulation is included in the scheme of development of a project, then the nominal flow is adjusted to take the most com- plete advantage of the discharge possible. "PRIMARY CAPACITY" is taken as one- eleventh of the product of the regulated flow and the mean effective head. This assumP.s that the product of efficiency and utilization factor is 0.80. In those streams which are unregulated the primary or nominal flow is taken as indicated in each report. "AVERAGE CAPACITY" is taken as one- eleventh of the continued product of the mean flow, the mean effective head and a factor rep- resenting the proportion of the unregulated flow which can be conducted to the power house at a reasonable cost. Any excess flow available less than 10 percent of the time is not considered for use. LORING, REVILLAGIGEDO ISLAND NEAR PROJECT 110 ··~···------- Scaling logs within the protected waters of Naha Bay.
