Abstract (Umit: 200 words) Water resources data for the 1979 water year for Alaska consista of records of stage, discharge, and water quality of streams; stage and water quality of lakes; and water levels and water quali.ty in wells and springs. This report contains discharge records for 111 gaging stations; stage only records for 2 gaging stations; water quality for 58 stations; and water levels for 30 observation wells. Also included are 62 law- flow, 89 crest-stage, and 24 water-quality partial-record stations. Additional water data were collected at various sites, not part of the systematic data collection program, and are published as miscellaneous measurements of discharge, lake stage, or water quality. These data represent that part of the National Water Data System operated by the U.S. Geological Survey and cooperating State and Federal agencies in Alaska. 17. Document Analysis a.

This volume contains records for water discharge at 111 gaging stations; stage only at 2 gaging stations; water quality at 58 gaging stations; and water levels for 30 observation wells. Also included are data for 62 low-flow, 89 crest-stage, and 24 water-quality partial-record stations and 20 lakes. Additional water data were collected at various sites not involved in the systematic data-collection program and are published as miscella- neous measürements and analyses. These data represent thàt part of the National Water Data System operated by the U.S. Geo1ogica1 Survey and cooperating State and Federal agencies in Alaska. Records of discharge and stage of streams, stage of lakes, chemical quality, water tempera- tures, and suspended sediment were first published in U.S. Geological Survey water-supply papers. Through September 30, 1960, these data were published in seven water-supply papers entitled, "Quantity and Quality of Surface Waters of Alaska" (through 1950, 1951-53, 1954-56, 1957, 1958, 1959, 1960). Since 1960, streamflow records and re1ated data were pub1ished in a five-year series of water-supply papers for 1961-65 and 1966-70 entit1ed, "Surface Water Supply of the United States." Water-quality records were published in a water-supp1y paper entitled "Quality of Surface Waters of Alaska, 1961-63" and after then until 1970 in an annual series of water-supply papers entitled, "Quality of Surface Waters of the United States." Records of ground-water levels were published from 1949 to 1974 in a series of water-supply papers entitled, ''Ground-Water ~eve1s in the United States." Water-supply papers may be consulted in the libraries of the principal cities in the United States or may be purchased from Branch of Distribution, U.S. Geological Survey, 1200 South Eads Street, Arlington, VA 22202. For water years 1961 through 1974, streamflow data were released by the Geological Survey in annual reports on a State-boundary basis. Water-quality records for water years 1964 through 1974 were simi1arly released either in separate reports or in conjonction with streamflow records. Beginning with the 1975 water year, water data for streamflow, water quality, ànd ground water are published in official Survey reports on a State-boundary basis. These official Survey reports carry an identification number consisting of the two-letter State abbreviation, the last two digits of the water year, and the volume number. For example, this report is id en tified as "U. S. Geolog- ical Survey Water-Data Report AK-79-1." For archiving and general distribution, the reports for water years 1971-74 are a1so identified as water-data reports. These water-data reports are for sale, in paper copy or in microfiche by the National Technical Information Service, U.S. Department of Commerce, Springfield, VA 22161. Additional information, including current priees, for ordering specifie reports may be obtain- ed from the district chief at the address given on the back of the title page or by telephone (518) 472-2457. COOPERATION The U.S. Geological Survey and organizations of the State of Alaska have had cooperative agree- ments since 1958 for the systematic collection of streamflow records, water-quality records, and ground-water levels. Organizations that assisted in collecting data through cooperative agreement with the Survey are: - Alaska Department of Natural Resources, R. E. LeResche, commissioner. Alaska Department of Fish and Game, R.O. Skoo,g, commissioner. Alaska Department of Transportation and Public Facilities in cooperation with the Federal Highway Administration, U.S. Department of Transportation, R. Ward, commissioner. Alaska Department of Environmental Conservation, E. W. Mueller, commissioner. Alaska Power Authority, E. P. Yould, executive director, Capital Site Planning Commission, R. L. Evans, administrati·;e director. Municipality of Anchorage, G. M. Sullivan, mayor. Kenai Peninsula Borough, D. E. Gilman, mayor. Fairbanks North Star Borough', J. A. Carlson, mayor. City and Borough of Juneau, M. Winegar, city manager. Thomas Bay Power Commission, R. L. Ballard, president. 1 2 WATER RESOURCES DATA FOR ALASKA, 1979 Assistance in the form of funds or services was given by the following federal agencies for information published in this report: Corps of Engineers, U.S. Army, for 26 gaging stations and 5 wat~r-quality stations; Forest Service, U.S. Department of Agriculture, for 14 gaging stations and 12 water-quality stations; Alaska Power Administration, U.S. Department of Energy, for 3 gaging stations; Sail Conservation Service, U.S. Department of Agriculture, for 3 gaging stations; and Environmental Protection Agency, for water-quality data. Organizations that supplied data are acknowledged in station descriptions. ACKNOWLEDGMENT Alaska district personnel who contributed significantly to the collection and preparation of the data in this report are too numerous ta mention individually. However., these people were in the following groups: Hydrology Section, R. D.' Lamke, chief; Anchorage Subdistrict, R. S.

HYDROLOGie CONDITIONS .Streamflow in Alaska for the 1979 water year was excessive (in the highest 25 percent for the period of record) at one-half of the long-term gaging stations (those stations with tcin or more years of record). The highest mean annual discharge during the period of record occurred at about ten percent of the stations. Most of these stations were in Southeast Alaska (at Skagway and on Chichagof Island); the other stations with new maximum annual discharges were Myrtle Creek near Kodiak and Snake River near Nome. Other stations with excessive or above normal annual flows were in Southeast Alaska (except the southernmost portion), South-central Alaska, and in those areas in the Interior that have streams that originate in glaciers. Streams with generally below normal flows for the year were those in Interior Alaska that have little runoff from glaciers and those in the s 0 uthernmost portion of Southeast Alaska. No outstanding or widespread floods occurred during the year. In Southeast Alaska, streamflow during Octbber was excessive at all stations (and the highest of record at about two-thirds of the stations) because of rains throughout the month. It was a very rare day that the weather stations in Southeast Alaska did not record sorne precipitation. Runoff declined until February when all of the stations had below normal or deficient flows. Runoff in the April through September period varied. Most streams on the islands had below normal or deficient flows and glacier-fed streams on the mainland had above normal or excessive flows. Excessive October mean flows were also experienced in South-central streams that have a mari- time climate. However, most of the streams further from the coast had below normal or deficient flows in October. Wintertime temperatures mostly were above normal; this resulted in above normal or excessive streamflow during the winter in most streams that are ice covered throughout the winter and with.headwaters at higher altitudes. April flows generally were above normal or exces- sive prior to breakup. There was a larger than normal snowpack at higher altitudes that resulted in above normal or excessive snowmelt runoff in the May through July period. Streamflow in South- central Alaska decreased ta more normal levels because of the· lack of precipitation in most 6f August and the first half of September. · In the rest of Alaska, October streamflows were generally below,normal and in a few cases were deficient. The mild winter generally resulted in above normal or excessive flows during the winter months. Flows throughout the rest of the year generally were normal or above normal. However, summer flows in non-glacial streams tributary ta the Tanana River were usually below normal with the exception of during July, which had excessive precipitation. Breakup in these streams occurred earlier than usual which resulted ·in record or near-record monthly mean discharges during April. Monthly and annual mean discharge for 1979 is compared in figure 3 with median monthly and annual discharge for the period of record at six representative gaging stations throughout the state. DEFINITION OF TERMS Terms related to streamflow, water-quality, and other hydrologie data, as used in this report, are defined as follows. See also the table for converting English Units ta International System of units (SI) on the inside of the back caver. Acre-foot (AC-FT, acre-ft) is the quantity of water required to caver 1 acre to a depth of 1 foot and is equivalent to 43,560 cubic feet or about 326,000 gallons or 1,233 cubic meters. Algae are mostly aquatic single-celled, colonial, or multi-celled plants, containing chloro- phyll-ana-lacking roots, stems, and leaves. WATER RESOURCES DATA FOR ALASKA, 1979 3 Algal growth potential (AGP) is the maximum algal dry weight biomass that can be produced in a natural water sample under standardized laboratory conditions. The growth potential is the algal biomass present at stationary phase and is expressed as milligrams dry weight of algae produced per liter of sample. Aquifer is a geologie formation, group of formations, or part of a formation that contains sufficient saturated permeable material to yield significant quantities of water to wells and springs. Artesian means confined and is used to describe a well in which the water level stands above the top of the aquifer, tapped by the well. A flowing artesian well is one in which the water level is abov~ the land surface. Bacteria are microscopie unicellular organisms, typically spherical, rodlike, or spiral and threadlike in shape often clumped into colonies. Sorne bacteria cause disease, others perform an essential role in nature in the recycling of materials; for example, by decomposing organic matter into a form available for reuse by plants. · Total coliform bacteria are a particular group of bacteria that are used as indicators of possible .sewage pollution. They are characterized as aerobic or facultative anaerobie, gram- negative, nonspore-forming, rod-shaped bacteria which ferment lactose with gas formation with- in 48 hours at 35°C. In the laboratory these bacteria are defined as all the organisms which produce colonies with a golden-green metallic sheen within 24 hours when incubated at 35"C ± l.O"C on M-Endo.medium (nutrient medium for bacterial growth). Their concentrations are expressed as number of colonies per 100 milliliters (mL) of sample. Fecal coliform bacteria are bacteria that are present in the intestine or feces of warm- blooded an1mals. They are often used as indicators of the. sanitary quality of water. In the laboratory they are defined as all organisms which produce blue colonies within 24 hours when incubated at 44.5°C ± o.z•c on M-FC medium (nutrient medium for bacterial growth). Their con- centrations are expressed as numbe.r of colonies per 100 mL of sample. Fecal streptococcal bacteria are bacteria found also in the intestine of warmblooded animals. Their presence 1n water is considered to verify fecal pollution, They are charac· terized as gram-positive, cocci bacteria which are capable of growth in brain-heart infusion broth. In the laboratory they are defined as all the organisms which produce red or pink colonies within 48 hours at 35"C ± l.O"C on M-enterrococcus medium (nutrient medium for bacte- rial growth). Their concentrations are expressed as number of colonies per 100 mL of sample. Bed material is the unconsolidated material of which a str•~ambed, lake, pond, reservoir, or estuary.bottom is composed. Benthic organisms (invertebrates) are animais inhabiting the bottom of an aquatic environment. They include a number of different types of organisms, such as hacteria, fungi, insect larvae and nymphs, snails, clams, and crayfish .-They are frequen tl y used 11s indicators of environmental qual- ity because many have restricted mobility during their aquatic llife phase, as well as a relatively long lifespan which allows for response to prevai ling and changimg water-quali ty conditions. ~1any benthic organisms inhabit specifie types of environments which, if changed, result in changes in the composition of the benthic community, Biomass is the amount of living matter present at any givern time, e~pressed as the mass per unit area or volume of habitat. Ash mass is the mass or amount of residue present after the residue from the dry mass determ1nat1on has been ashed in a muffle furnace at a temperature of soo•c for 1 hour. The ash mass values of zooplankton and phytoplankton are e~pressed in grams per cubic meter (g/m 3 }, and periphyton and benthic organisms in grams per square meter (g/m 2 ). Dry mass refers to t~e mass of residue present after drying in an oven at 60°C for zoo• plankton and 105°C for periphyton, until the mass remains unchanged. This mass represents the total organic matter, ash and sediment, in the sample. Dry mass values are expressed in the same units as ash mass. · Or~anic mass or volatile mass of the living substance is the difference between the dry mass an the ash mass, and represents the actual mass of the living matter. The organic mass is expressed in the same units as for ash and dry mass. Wet mass is the mass of living matter plus contained water. 4 WATER RESOURCES DATA FOR ALASKA, 1979 Bottom material: See Bed material; Recoverable from bottom material is the amount of a given constituent that is in solution after a representative sample of bottom material has been digested by a method (usually using an acid or mixture of acids} that results in dissolution of only readily soluble substances. Complete dissolution of all bottom material is not achieved by the digestion treatment and thus the determination represents less than the total amount (that is, less than 95 percent) of the constituent in the sample. To achieve comparability of analytical data, equivalent digesêion procedures would be required of all laboratories performing such analyses because different 'digestion procedures are like ly to nroduce different analytical re sul ts. Total in bottom material is the total amount of a given constituent in a representative sample of bottom material. This term is used only when the analytical procedure assures meas- urement of at least 95 percent of the constituent determined. A knowledge of the expected form of the constituent in the sample, as well as the analyticàl methodology used, is required to judge when the results should be reported as "total in bottom material", Cells/volume refers to the number of cells of any organism which is counted by using a micro- scope and gn.d or counting cell. Many planktonic organisms are mul ticelled and are counted according to the number of contained cells per sample, usually milliliters o~ liters (L). Cfs-day is the volume of water represented by a flow of 1 cubic foot per second for 24 hours. It is equ1valent to 86,400 cubic feet, approximately 1.9835 acte-feet, or about 646,000 gallons or 2,447 cubic meters. Chlorophyll refers to the green pigments of plants. Chlotophyll ~ and ~ are the two most common green p1gments in plants. - Color unit is produced by one milligram per liter of platinum in the form of the chloroplatin- ate ion. Color is expressed in units of the platinum-cobalt scale. Control designates a feature downstream from the gage that determines the stage·discharge relat1on at the gage. This feature may be a natural constriction of the channel, an artificial structure, or a un!form cross section over a long reach of the channel. Cubic feet per second per square mile (CFSM) is the average number of cubic feet of water flowing per second from each square m1le of area drained, as.suming that the runoff is distribtited uniformly in time and area. Cubic foot per second (FT 3 /S, or ft 3 /s) is the rate of discharge representing a volume of 1 cubic foot pass1ng a g1ven point during 1 second and is equivalent to approximately 7.48 gallons per second or 448.8 gallons per minute or 0.02832 cubic meters per second. Discharge is the volume of water (or more broadly, volume of fluid plus suspended sediment) that passes a given point within a given period of time. Mean discharge (MEAN)_ is the arithmetic mean of individual daily mean discharges during a spec1f1c period. Instantaneous discharge is 'the discharge at a particular instant of time. Dissolved refers to that material in a representative water sample which passes through a 0.45 micrometer membTane filter. This is a convenient operational definition used by Federal agencies that collect water data. Determinations of "dissolved" constituents a:re made on subsamples of the filtra te. Drainage area of a stream at a specifie location is that area, measured in a-horizontal plane, enclosed by a topographie divide from which direct surface runoff from precipitation normally drains by gravity into the stream above the specified point. Figures of drainage area: given herein include all closed basins, or noncontributing areas, within the area unless otherwise noted. Ga se height (G. H.) is the wa ter-surfa'ce eleva ti on :referred ta some arbitrary gage datum. Gage height 1s often used interchangeably with the general term "stage," although gage height is more appropriate when used with a reading on a gage. Gaging station is a particular site on a stream or lake whe:re systemat:ic observat:ions of hydro- logie data are obtained, Hardness of water is a physical-chemical characteristic that is commonly recognized· by the increased quantity of soap required to produce lather. It is attributable to the presence of alka:- line earths (principall~ calcium and magnesium) and is expressed as equivalent calcium carbonate (CaC0 3 ). Hydrologie unit is a geographie area representing part or all of a surface drainage basin or distinct hydrologlc feature as delineated by the Office of Water Data Coordination on the State Hydrologie Unit Maps; each hydrologie unit is identified by an 8-digit number. WATER RESOURCES DATA FOR ALASKA, 1979 Methylene blue active substance (MBAS) is a measure of apparent detergents. This determina- tion depends on the formation of a blue color when methylene blue dye reacts with synthetic detergent compounds. 5 Micrograms per liter (UG/L, Jlg/L) is a unit expressing the concentration of chemical constitu- ents 1n solution as mass (micrograms) of solute per unit volume (liter) of water. One thousand micrograms per liter is equivalent to one milligram per liter. Milligrams per liter (MG/L, mg/L) is a unit for expressin~: the concentration of chemical constituents in solution. Milligrams per liter represents the mass of solute per. unit volume (liter) of water. Concentration of suspended sediment also is expressed in mg/L, and is based on the mass of sediment per liter of water-sediment mixture. National Geodetic Vertical Dafum of 1929 (NGVD) is a geodetic datum derived from a general adjustment of the first arder level nets of both the United States and Canada. It was formerly called "Sea Level Datum of 1929" or "mean sea level" in this series of reports. Although the datum was derived from the average sea level over a period of many years at 26 tide stations along the Atlantic, Gulf of Mexico, and Pacifie Coasts, it does not necessarily represent local mean sea level at any particular place. Organism is any living entity, such as an insect, phytoplankter, or zooplankter, Organism count/area refers to the number of orgçmisms collected and enumerated in a sample and adjusted to the number per area habitat, usually square meters (m 2 }, acres, or hectares. Periphyton, benthic organisms, and macrophytes are expressed in these terms. Qrganism count/volume refers to the number of organisms collected and enumerated in a.·. sample and adjusted to the number per sample volume, usually milliliters (mL) or litèrs (L). Numbers of planktonic organisms can be expressed in these terms. Total organism count is the total number of organisms collected and enumerated in any particular sample; Partial-record station is a particular site where limited streamflow or water-quality data are collecrea:-systematically over a period of years for use in hydrologie analyses. Particle size is the d{ameter, in millimeters (mm), of suspended sediment or bed material determined by either sieve or sedimentation methods. Sedimentation methods (pipet, bottom•with- drawal tube, visual-accumulation tube) determine fall diameter of particles in either distilled water (chemically dispersed) or in native water (the river water at the time and point of sampling). Particle-size classification used in this report agrees with recommendations made by the American Geophysical Union Subcommittee on Sediment Terminology. The classification is as follows: Classification Clay .........• Silt ......... . Sand ......•.•. Gravel ....... . Size (mm) 0.00024 - .004 .062 0.004 .062 2.0 2.0 -64.0 Method of analysis Sedimentat on. Sedimentat on. Sedimentat on or sieve. Si eve. The particle-size distribution given in this report are not necessarily representative of all particles in transport in the stream. Most of the organic material is removed and the sample is subjected to mechanical and chemical dispersion before analysis in distilled water. Chemical dis- persion is not used for native-water analysis. Periphyton is the assemblage of microorganisms attached to and growing upon solid surfaces. Pesticides are chemical compounds used to control un desirable plants and animals. Major . categories of pesticides include insecticides, miticides, fungicides, herbicides, and rodent±cides. Insecticides and herbicides, which control insects and plants re~>pectively, are the two categories reported. Picocuri (PC, pCil is one trillionth (1 x 1012 )_ of the amount of radioactivity represented by a cura (Cl). A curie is the amount of radioactivity that yields 3.7 x 10 10 radioactive disinte· grations per second. A picocurie yields 2.22 dpm (disintegrations per minute). Plankton is the community of suspended, floating, or weakly swimming organisms that live in the open water of lakes and rivers. · 6 WATER RESOURCES DATA FOR ALASKA, 1979 Phytoplankton is the plant part of the plankton. They are usually microscopie and their movernent 1s subject to the water currents. Phytoplankton growth is dependent upon solar radi- ation and nutrient substances. Because they are able to incorporate as well as release mate- rials to the surrounding water, the phytoplankton have a profound effect upon the quality of the water. They are the primary food producers in the aquatic environment, and are commonly known as algae. Blue-green algae are a group of phytoplankton organisms having a blue pigment, in addition to the green pigment called chlorophyll. Blue-green algae often cause nuisance conditions in water. Diatorns are the unicellular or colonial algae having a siliceous shell. Their con- centrations are expressed as number of cells/mL of sample. Green algae have chlorophyll pigments similar in color to those of higher green plants. Sorne forms produce algal mats or floating "moss" in lakes. Their concentrations are expressed as number of cells/mL of sample. Zooplankton is the animal part of the plankton. Zooplankton are capable of extensive movements w1th1n the water column, and are often large enough to be seen with the unaided eye. Zooplankton are secondary consumers feeding upon bacteria; phytoplanlton, and detritus. Because they are the grazers in the aquatic environment, the zooplankton are a vital part of the aquatic food web. The zooplankton community is dominated by small crustaceans and rotifers. Polychlorinated biphenyls [PCBsl are industrial chemicals that are mixtures of chlorinated biphenyl cornpounds hav1ng various percentages of chlorine. They are similar in structure to organochlorine insecticides. Runoff in inches (IN, inl shows the depth to which the drainage area would be covered if all the runoff for a g:LVen ti me period were uniformly dis tributed on i t. Sediment is solid material that originates mostly from disintegrated rocks and is transported by, suspended in, or deposited from water; it includes chemical and biochemical precipitates ·and decomposed organic material such as humus. The quantity, characteristics, and cause of the occur- rence of sediment in streams are influenced by environmental factors. Sorne major factors are degree of slope, length of slope, soil characteristics,' land usage, and quantity and intensity of precipitation. Suspended-sediment is the sediment that at any given time is maintained in suspension by the upward components of turbulent currents or that exists in suspension_, as a colloid. SUspended-sediment concentration is .the velocity-weighted concentration of suspended sediment in the sampled zone (from the water surface to a point approximately 0.3 ft above the bed)_ express·ed as milligrams of dry sediment per liter of water-sediment mixture (mg/L). ~~~t'~ .. ---~--~"'-.. " -~~~ .. --5 e (tons/dayl :is the rate at which dry weight of sediment d~ ·· -" · ~ · • .. 1s the quanti ty of sediment, as measured by dry weight or given time. Ii: is computed by multiplying discharge times Suspended-sediment load is quantity of suspended sediment passing a section in a speci· fied per1od. Total sediment dtschar~e (tons(day)_ is the sum of the suspended-sediment discharge and the bedload d1scharge. Jt lS the total quantity of sediment, as measured by dry weight or volume, that passes a section during a given time. Mean concentration j:s the time-weighted concentration of suspended sediment passing a stream sect1on durtng a 24-hour day. Solute is any substance derived from the atmosphere, vegetation, soil, or rocks that is dis- solveèfl:ïlWater. Specifie conductance is a measure of the ability of a water to conduct.an electrical current and is expressed :rn m·rcromhos per centimeter at zs•c. Specifie conductance is related to the type and concentration of ions in solution and can be used for approximating the dissolved-solids con- tent in the water. Commonly, the concentration of dissolved solids (in milligrams per liter) is about 65 percent of the specifie conductance (in micromhos)• This relation is not constant from stream to stream, and it may vary in the same source with changes in the composition of the water. Stage-discharge relation is the relation between gage height (stage) and volume of water per unit of t~me, flowing 1n a channel.· Strearnflow is the discharge that occurs in a natural .channel. Although the term "discharge" can.lre appl1ed to the flow of a canal, the word "streamflow" uniquely describes the di:;;charge in a ,surface stream course, The term "streamflow" is more general than "runoff" as streamflow may be applied to discharge whether or not it is affected by diversion or regulation. WATER RESOURCES DATA FOR ALASKA, 1979 7 Substrate is the physical surf~ce upon which an organism lives. Artificial substrate is a deviee which is purposely placed in a stream or lake for colo- nization of organisms. The use of artificial substrates simplifies the community structure by standardizing the substrate from which each sample is taken. Examples of artificial sut- strates are basket samplers (made of wire cages filled with clean streamside rocks) and multi-plate samplers (made of hardboard) for benthic organism collection, and plexiglass strips for periphyton collection. Suspended, recoverable is the amount of a given constituent that is in ~olution after the part of a representative water-suspended sediment sample that is retained on a 0.45 micrometer membrane filter has been digested by a method (usually using a dilute acid solution) that results in dissolu- tion of only readily soluble substances. Complete dissolution of all the particulate matter is not achieved by the digestion treatment and thus the determination ·represents something less than the "total" amount (that is, less than 95 percent) of the constituent present in the sample. To achieve comparability of analytical data, equivalent digestion procedures would be required of all labora- tories performing such analyses because different digestion procedures are likely to produce different analytical results. Determinations of "suspended, recoverable" constituents are made either by analyzing portions of the material collected on the filter or, more commonly, by difference, based on determinations of (1) dissolved and (2) total recoverable concentrations of the constituent. Suspended, total is the total amount of a given cons.tituent: in the part of a representative water-suspended sedJ.ment sample that is retained on a 0.45 micrometer membrane filter. This term is used only when the analytical procedure assures measurement .c'f at least 95 percent of the con- stituent determined. A knowledge of the expected form of the cc,nstituent in the sample, as we·ll as the analytical methodology used, is required to determine when the results should be reported as "suspended, total". Determinations of "suspended, total" constituents are made either by analyzing portions of the material collected on the filter or, more commonly, by difference, based on determinations of (1) dissolved and (2) total concentrations of the constituent. Taxonomy is the division of biology c.oncerned with the classification and naming of organ- isms. The classification of organisms is based upon a hierarchical scheme beginning with Kingdom and ending with Species at the base. The higher the classification level, the fewer features the organisms have in common. For example, the taxonomy of a particular mayfly, Hexagenia limbata is the following: Kingdom. ,, .... , ......... Animal Phylum ...•.... , • , , .. Arthropoda Class ..•..•.......•.... Insecta Order ......•..•.. Ephemeroptera Family .•...•...•... Ephemeridae Genus ..........••.... Hexagenia spëëTes .-... ,, Hexagen;ia limbat::!l:. Tons per acre-foot indicates the dry weight of dissolved solids in 1 acre-foot of water. It is computed by multJ.plying the concentration in milligrams per liter by 0.00136. Tons per day is the quantity of a substance in solution or o:uspension that passes a stream section durîng a 24-hour day,. Total, recove·rable is the amount of a given constituent that is in solution after a represent- tative water-suspended sediment sample has been digested by a method (usually using a dilute acid solutionl that results in dissolution of only readily soluble substances. Complete dissolution of all particulate matter is not achieved by the digestion treatment, and thus the determination repre- sents something less than the "total" amount (that is, less than 95 percent) of the constituent pre- sent in the dissolved and suspended phases of the sample. To achieve comparability of analytical data, equivalent digestion procedures would be required of all laboratories performing such analyses because different digestion procedures are likely to produce different analytical results. Total is the total amount of a given constituent in a representative water-suspended sediment sample, regardless of the constituent's physical or chemical form. This term is used only when the analytical procedure. assures measurement of at least 95 percent of the constituent present in both the dissolved and suspended phases of the sample. A know1edge of the expected form of the constit- uent in tbe sample, as well as the analyt:i.cal methodology-used, is required to judge when the results should be reported as "total", (Note that the word "total" does double duty here, indicating both that the sample consists of a water-suspended sediment mixture and that the analytical method determines all of the constituent in the sample.J WRD is used as an abbreviation for "Water-Resources Data" in the REYISED RECORDS paragraph to refer-r0 State annual basic-data reports published before 1975. WSP is used as an abbreviation for "Water-Supply Paper" in references to prev;i.ously published reports. 8 .WATER RESOURCES DATA FOR ALASKA, 197~ DOWNSTREAM ORDER AND STATION,NUMBER Since October 1, 1950, the arder of listing hydrologie-station records in Survey reports is in a downstream direction along the main stream. All stations on a tributary entering upstream from a main-stream station are listed before that station. A station on a tributary that enters between two main-stream stations is listed.between them. A similar arder is followed in listing stations on first rank, second rank, and other ranks of tributaries. The rank 'of any tributary on which a station is situated with respect to the stream to which it is ·immediately tributary is indicated by an indention in a list of stations in the front of the report. Bach indention rep- resents one rank. This downstream arder and system of indention show which stations are on tributaries between any two stations and the rank· of the ·tributary on which each station is situated. · As an added means of identification, each hydrologie station and partial-record station has been assigned a station number. These are in the same downstream order used in this report. In assigning station numbers, no distinction is made between partial-record stations and other stations; therefore, the station number for a partial-record station indicates downstream-order position in a .. list made up of bath types of stations. Water-quality stations located at or near gaging stations or partial-record stations have the same number as the gaging or partial-record station. Gaps are left in the series of numbers to allow foJ new .stations that may be established; hence, the numbers are not consecutive. The complete 8-digit number for each station, such as 15303600, which appears just to the left of the station name, includes the 2-digit part number "15" plus;the 6-digit downstream order number "303600." NUMBERING SYSTEM FOR WELLS AND MISCELLANEOUS SITES The 8-digit downstream arder station numbers are not assigned to wells and miscellaneous .sites where only random water-quality samples or discharge measurements are taken. The well and miscellaneous site numbering system of the U.S. Geological Survey is based on the grid system of latitude and longitude. The system provides the geographie location of the well or miscellaneous site and a unique number for each site. The number consists of 15 digits. The first 6 digits denote the degrees, minutes, and seconds of latitude, the next 7 digits denote degrees, minutes, and seconds of longitude, and the last 2 digits (assigned sequentially) iden- tify the wells or ether sites within a 1-second grid. See figure 1 below.

System for numbering wells and miscellaneous sites (latitude and longitude) SPECIAL NETWORKS AND PROGRAMS Hydrologie bench-mark station is one that provides hydrologie data for a basin in which the hydrologie regimen will likely be governed solely by natural conditions. Data collected at a bench-mark station may be used to separate effects of natural from manmade changes in ether basins which have been developed and in which the physiography, climate, and geology are similar to those in the undeveloped bench-mark basin. National strearn-quality accounting network (NASQAN) is a data collection network designed by the U.S. Geological Survey to meet many of the information demands of agencies or groups involved in national or regional water-quality planning and management, Both accounting and broad-sc&le monitoring objectives have been incorporated into the network design. Areal configuration of the WATER RESOURCES DATA FOR ALASKA, 1979 9 nêtwork is baSed on river-basin accounting units (identified by 8-digit hydrologie-unit numbers) designated by the Office of Water Data Coordination in consultation with the Water Resources Council. Primary objectives of the network are (1) to depict areal variability of streamflow and water-quality conditions nationwide on a year-by-year basis and (2) to detect and assess long-term changes in streamflow and stream quality. Pesticide program is a network of regularly sampled water-quality stations where samples are collected to determine the concentration and distributuon of pesticides in streams where potential contamination could result from the application of the commonly used insecticides and ·herbicides. Operation of the network is a Federal interagency activity. Radiochemical program is a network of regularly sampled water-quality stations where samples are collected to be analyzed for radioisotopes. The streams that are sampled represent major drainage basins. EXPLANATION OF STAGE AND WATER-DISCHARGE RECORDS Collection and computation of data The base data collected at gaging stations consist of records of st~ge and measurements of discharge of streams and stage of lakes. In addition, observations of factors affecting the stage- discharge relation, weather records, and other information are used to supplement base data in · determining the daily flow. Records of stage are obt,inedfrom direct readings On a nonrecording gage or from a water-stage recorder that gives either a continuous graph of the fluctuations or a tape punched at selected time intervals. Measurements of discharge are made with a current meter, using the general methods adopted by the Geological Survey. These methods are described in standard textbooks, in Water-Supply Paper 888, and in U.S. Geological Survey Techniques of Water Resources Investigations, book 3, chapter A6. For stream-gaging stations, rating tables giving the discharge for any st~ge are prepared from stage~discharge relation curves. If extensions to the rating curves are necessary to express discharge greater than measured, they are made on the basis of indirect measurements of peak discharge (such as slope-area or contracted-opening measurements, computation of flow over dams or weirs), step-backwater techniques, velocity-area studies, and logarithmic plotting. The daily mean discharge is computed from gage heights and rating tables, .then the monthly and yearly mean discharge are computed from the daily figures. If the stage-discharge relation is subject to change because of frequent or continua! change in the physical features that form the control, the daily mean discharge is computed by the shifting-control method, in which correction factors based on individual dischirge measurements and notes by engineers and observers are used in ap- plying the gage heights to the rating tqbles. If the stage-discharge relation for a station is temporarily changed by the presence of aquatic growth or debris on the control, the daily mean discharg~ is computed by what is basically the shifting-control method. At most stream-gaging stations in Alaska the stage-discharge relation is affected by ice in the winter, and it becomes impossible to compute the discharge in the usual manner. Discharge for periods of ice effect is computed or estimated on the basis of the available gage-height record and occasional winter discharge measurements. Consideration is given ta the available information on temperature and precipitation, notes by gage observers and hydrologists, and comparable records of discharge for other stations in the same or nearby basins. For sorne gaging stations there are periods when no gage-height record is obtained or the recorded gage height is so faulty that it cannet be used to compute daily discharge. This happens when the recorder is stopped for the winter or otherwi.se fails to operate properly, intakes are plugged, the float is frozen in the well, or for various other reasons. For such periods the daily discharges are estimated on the basis of recorded range in ~;tage, prior and ~ubsequent records, discharge measurenients, weather records, and comparison with records for other stations in the same or nearby basins. ' The data in this report generally comprise a description of the station and tabulations of daily and monthly figures. For gaging stations on streams a table showing the daily discharge and monthly and yearly discharge is given. Tables of daily mean gage heights are included for sorne streamflow stations. Records are published for the water year, which begins on October 1 and ends on September 30. The description of the gaging stations gives the location, drainage area, period of record~ notations of revisions of previously published records, type and history of gages, general remarks, average discharge, and extremes of discharge. The location of the gaging station anù the drainage area are obtained from the most accurate maps available. Periods for which there are published records for the present station or for stations generally equivalent to the present one ~re glven under "PERIOD OP RECORD." 10 WATER RESOÙRCES DATA FOR ALASKA, 1979 Previously published streamflow records of sorne stations have been found to be in errer on the basis of data or ~nformation later obtained. Revisions of such records are usually published along with the current records in one of the annual or compilation reports. In arder to make it easier to find such revised records, a paragraph headed "REVISED RECORDS" has peen added to the' description of all stations for which revised records have been published. Listed therein are all the reports in which revisions have been published, each followed by the water years for which figures are revised in that report. In listing the water years only one number is given; for instance, 1965 stands for the water year October 1, 1964, to September 30, 1965. If no daily, monthly, or annual figures of discharge are affected by the revision, the fact is brought out by notations after the year dates as follows: "(M}" means that only the instantaneous maximum dis- charge was revised; "(rn)" that only the instantaneous minimum was·revised; and "(P)" that oniy peak discharges were revised. If the drainage area has been revised, the report in which the revised figure was first published is given, It should be noted that for all stations for which cubic feet per second per square mile and runoff in inches are published, a revision of thè drain- ige area necessitates corresponding revision of all figures based on the drainage area. Revised figures of cubic feet per second per square mile and runoff in inches resulting from a revision of the drainage area only are usually not published in the annual series of reports. ' The type of gage currently in use, the datum of the present gage referred to National Geodetic Vertical Datum, and a condensed history of the types, locations, and datums of previous gages used during the period of record are given under "GAGE." National Geodetic Vertical Datum is explained in "DEFINITION OF TERMS" on page 5. Information pertaining to the accuracy of the discharge records and to conditions which affect the natural flow of the gaging station is given under "REMARKS." The average discharge for the number of years indicated is given under "AVERAGE DISCHARGE"; It is not given for stations having fewer than 5 complete years of record. Under "EXTREMES" are given first, the extremes for the period of record, second, information available out.side the period of record, and last, those for the current year. Unless otherwise qualified, the maximum discharge is the instantane'ous maximum corresponding to the crest stage obtained by use of a water-stage recorder (graphie or digital}, a crest-stage gage, or a nonrecording gage read at the time of the crest. If the maximum gage height did not occur on the same day as the maximum dis- charge, it is given separately. Similarly, the minimum is the instantaneous minimum unless ether- wise qualified. For sorne stations peak discharges are listed with EXTREMES FOR THE CURRENT YEAR; if they are, all independent peaks, including the maximum for the year, above the selected base with the time of occurrence and corresponding gage heights are published in tabular format. The base discharge, which is given in the table heading, is selected so that an average of about three peaks a year will be presented. Peak discharges are not published for any canals, ditches, drains, or for any.stream for which the peaks are subject to substantial control by man. Time of day is expressed in 24-hour local standard time; for example, 12:30 a.m. is 0030, 1:30 p.m. is 1330. The miniinums for these stations are published in a sepa:rate paragraph following the table of peaks. The daily table for stream-gaging stations gives the mean discharge for each day and is by monthly and yearly summaries. In the monthly summary below the daily table, thé line headed "TOTAL" gives the sum of the daily figures. The line headed "MEAN" gives the average flow in cubic feet per second during the month. The lines headed "MAX" and "MIN" give the maximum and minimum daily discharges, respectively, for the month. Discharge for the month also may be expressèd in cubic feet per second per square mile (line headed "CFSM") , or in inches Cline headed "IN"), or in acre-fe et (li ne headed "AC-FT"l, Figures for cub ic fe et per second per square mi le and runoff in inches· are omitted .if there is extensive regulation or diversion, if the drainage are a includes large noncontributiiig arèas, or if most of the flow is from a spring. In the yearly summary be law the monthly summary, the figures shown are the approp:date da il y discharges for the calendar and water years. Footnotes to the table of daily discharges are introduced by the word "NOTE." Footnotes are used to indicate periods for which the discharge is computed or estimated bY special methods because of no gage-height record, backwater from various sources, or other unusual conditions. Periods of no gage.-height record are indicated if the period is continuous for a month or,more or includes the maximum discha~ge for the' year. Periods of backwater from an unusual source of igde- finite sta.ge-discharge relation, or of any other unusual condition at the gage site are indicated only if they are a month or more in length and the accuracy of the records is affected. Days on which the stage-discharge relation is affected by ice are not indicated. The methods used in computing discharge for various unusual conditions have been explained in preceding paragraphs. Data collected at partial-record stations follow the information for continuous record sites. Data for partial-record discharge stations are presented in two tables. The first is a table of discharge measurements at low-flow partial-record stations, and the second is a table of annual maximum stage and discharge at crest-stage stations,, The tables of partial-record stations are followed by a listing of discharge measurements made àt sites ether than continuous-record or partial-record stations. Occasionally, a series of discharge measurements are made within a short time period to investigate the seepage gains or losses along a reach of a stream or to determine the low-flow characteristics of an area. Such measurements are also given in special tables following the tables of partial-record stations. Lake-level data collected at mis~ellaneous selected lakes are tabulated also. WATER RESOURCES DATA FOR ALASKA, 197!1 11 Accuracy of field data and computed results The accuracy of streamflow data dep~nds primarily on (1) the stability of the stage-discharge relation or, if the control is unstable, the frequency of discharge measurements, and (2) the accuracy of observations of stage, measurements of discharge; and interpretations of records. The station description under "REMARKS" states the degree of accuracy of the records. "Excellent" means that about 95 percent of the daily discharges are within 5 percent; "good" within 10 percent; and "fair" within 15 percent. "Poor" means that daily discharges have less than "fair" accuracy. Figures of daily mean discharge in this report are shown to the nearest hundredth of a cubic foot per second for discharges of 1ess than 1 ft 3 /s; to tenths between 1.0 and 10 ft 3 /s; to whole numbers between 10 and 1,000 ft 3 /s; and to 3 significant figures above 1,000 ft 3 /s. The number of significant figures used is based solely on the magnitude of the figure. The same rounding rules apply to discharge figures listed for partial-record stations~ Discharge at many s·tations, as indicated by the monthly mean, may not reflect natural runoff due to the effects of diversion, flow from springs, or to other factors. For such stations, figures of cubic feet per second per square mile and of runoff in inches are not published unless satisfactory adjustments can be made for diversions or for other changes incident to use and control; Other data available Information of a more detailed nature than that published for most of the gaging stations such as observations of water temperatures, discharge measurements, gage-height records, and rating tables, is filed in the subdistrict oifices at Anchorage, Fairbanks, and Juneau for their areas of responsibility. Also most gaging-station records are available in computer-usable form and many statistical analyses have been made. Information on the avail~bility of unpublished data or statistical analyses may be obtained from the district office~ EXPLANATION OF WATER QUALITY RECORDS Collection and examination of data Surface water samples for analyses usually are collected at or near gaging stations. The quality-of-water records are gi~en immediat~ly following the discharge records at these stations. The descriptive heading for water-quality records gives the period of record for ali water- quality data; the period of daily. record for parameters that are measured on a daily basis (specifie conductance, pH, dissolved oxygen, water temperature, sediment discharge, etc.); extremes for the period of daily record; extremes for the current year; and general remarks. For ground-water records, no descriptive statements are given; however, the well number, depth of well, date of sampling and/or other pertinent data are given in the table containing the chemical analyses of the gr6und water. Water analysis Most methods for collecting and analyzing water samples are described in the u.s. Geological Survey Techniques of Water-Resources Investigations listed on a following page. One sample can define adequately the water quality at a given time if the mixture of solutes throughout the stream cross section is homogeneous. However, the concentration of solutes at different locations in the cross section may vai:y widely with different rates of water discharge, depending on the source of material and the turbulence and mixing· of the stream. Sorne streams must be sampled through several vertical sections to obtain a representative sample needed for an accurate mean concentration and for use in calculating load. Chemical-quality data published in this report are considered ~o be the most representative values available for the stations listed. The values reported represent water-quality conditions at the time of sampling as much as possible, consistent with available sampl{hg techniques and methods of analysis. In the rare case where an apparent inconsistency exists between a reported pH value and the relative abundance of carbon dioxide species (carbonate and bicarbonate), the inconsistency is the r~sult of a slight uptake of carbon dioxide from the air by the sample between measurement of pH in the field and determination of carbonate and bicarbonate in the laboratory. 12 WATER RESOURCES DATA FOR ALASKA, 1979 Water temperature Water temperatures are measured at most of the water-quality stations. In addition, water temperatures are taken at time of discharge measurements for water-discharge stations. Large streams have a small diel temperature change; shallow streams may have a daily range of several degrees and may follow closely the changes in air temperature. Sorne streams may be affected by waste-heat discharges. · At stations where recording instruments are used, maximum and minimum temperatures for each day are published. Sediment Suspended-sediment concentrations are determine~ from samples collected ~y using depth-inte- grating sampler~. Samples usually are obtained at several verticals in the cross section, or a ' single sample may be obtained at a fixed point and a coefficient applied to determine the mean concentration in the cross sections. , During periods of rapidly changing flow or rapidly changing concentration, samples may have been collected more frequ'ently (twice daily or, in sorne instances, hourly). The published sediment discharges for days of rapidly changing ·flow or concentration were computed by the subdi vided day method ( time-discharge weighted average}. Therefore, for tho se da ys wh en the published sediment discharge value differs from the value computed as the product of discharge .times mean concentration times 0.0027, the reader can assume that the sediment discharge for that day was computed by the subdivided day method. For periods when no samples were collected, daily loads of suspended sediment were estimated on the basis of water discharge, sediment concentra- tions observed immediately before and after the periods, and suspended-sediment loads for other periods of similar discharge. At other stations, suspended-sediment samples were collected periodically at many verticals in the stream cross section. Although data collected periodically may represent conditions only at the time of observations, such data are useful in establishing seasonal relations between quality and streamflow in predicting long-term sediment-discharge characteristics of the stream. In addition to the records of the quantities of suspended sediment, records of the periodic measurements of the particle-size distribution of the suspended sediment and bed material are included. EXPLANATION OF GROUND-WATER LEVEL RECORDS Collection of the data Only ground-water level data from a basic ·network of observation wells are publ;ished herein. This basic network consists of observation wells located in the most important aquifers, and therefore the most significant data are obtained from the fewest wells. (See figure 4.) Each well is identified by means of (1} a 15-digit number that is based on latitude and longitude and (21 a local number that is provided for local needs, (See figure 1.1 The local number used herein is partly based on the rectangular subdivision of ,public lands. The first two letters indicate the principal meridian and the quadrant formed by the intersection of the base line and the principal meridian. The first three digits indicate the township in which the well ;Ls located, the next three digits the range, and the following two digits the section. Letters following the section number indicate the quarter section, the quarter-quarter section, and so forth to the fourth arder subdivision. Each of these subdivisions is lettered counter-clockwise, from the northeast corner. Each well within the smallest arder of subdivision is then given a sequential number. Finally, each well within a section is assigned a sequential map number using the last thr.ee digits. Thus, Sl?00601115BCAD1 indicated the Seward meridian (S), the northwest quadrant (BL township 6 n.orth, range 11 west,, section 15; and the well is in the SE~ of th~ NE~ of the SW~ of the NW~ of the section (BCAD), It was the first wellin the 2.5 acre "D" subdivision assigned a sequentia1 number (1). The next three digits, 001, indicate the sequence in which a well was located on a map. Thus 001 indicates it was the first well plotted in the one square mile section. The next space is left blank. The last five numbers, such as 00114, are the Alaska register number, that is provided for continuity with o1der reports. There· fore, th~ local number is SB00601115BCAD1001 00114. Measurements are made in many types of wells, under varying conditions of access.and at different temperature~; hence, neither the method of measurement nor the equipment can be standardized. At each observation well, however, the equipment·and techniques used are those that will ensure that measurements at each well are consistent. WATER RESOURCES DATA FOR ALASKA, 1979 13 Water-level measurements in this report are given in feet referred to either National Geodetic Vertical Datum (NGVD) or land~surface datum (lsd). National Geodetic Vertical Datum is the datum plane on which the national network of precise levels is based; land-surface datum is a·datum plane that is approximately at land surface at each well. If known, the altitude of the land-surface datum is given in the well description. The height of the measuring point (MP) above or below land- surface datum is given in each well description. Water levels in wells equipped with recording gages are reported for every fifth day and the end of each month (eom). Daily water levels are reported for a few wells that may have significant fluctuations between every fifth day. The extreme water levels recorded during the year are reported as the highest water level (HWL) and as the lowest water level (LWL). Water levels are reported to as many significant figures as can be justified by the local con- ditions. For example, in a measurement of a depth to water of several hundred feet or if an elec- tric water sensor myst be used, the errer in determining the absolute value of the total depth to water may be five or more hundredths of a foot. However, the errer in determining the net change of water level between successive measurements may be only a hundredth or a few hundredths of a foot. Accordingly, most measurements are reported to a hundredth of a foot, but a few are given only to a tenth of a foot, 14 ~,WATER RESOURCES DATA. FOR ALASKA, 1979 PUBLICATIONS ON TECHNIQUES OF WATER-RESOURCES INVESTIGATIONS Thirty-four manuals by the U.S. Geological Survey have been published to date in the series on techniques describing procedures for planning and executing specialized work , in water-resources investigations. The material is grouped under major subject headings called books and is further divided into sections and chapters. For example, Section A of Book 3 (Applications of Hydraulics) is'on surface water. The chapter, the unit of publication, is limited to a narrow field of subject matter. This format· permits flexibility in revision and publication as the need arises.

When limited streamflow data are collected on a systematic basis over a period of years for use in hydrologie analyses, the site at which the data are collected is called a partial- record station. Data collected at these partial-record stations are useable in law-flow or floodflow analyses, depending on the type of data collected. ln addition, discharge measuremen·ts are made at ether sites not included in the partial-record program. These measurements are generally made in times of drought or flood ta give better areal coverage to those events. Those measurements and others collected for sorne special reasan are called measurements at miscellaneous sites. Records collected at partial-record stations are presented in two tables. measurements at law-flow partial-record stations and the second is a table of crest-stage stations. Discharge measurements made at miscellaneous sites for in a third table. The first is a table of discharge annual maximum stage and discharge at bath law flow and high flow are giv·en Law-flow partial-record stations Measurements of streamflaw in Alaska made at law-flow partial-record stations are given in the following table. These measurements were made during periods of base flow when streamflow is primarily from ground-water storage. These measurements, when correlated with the simultaneous discharge of a nearby stream when continuons records are available, will give a picture of the law-flow potentiality of a stream. For sorne stations, measurements made periodically through the year are alsa included. The column headed "Period of record" shows the water years in which measurements were made at the same, or practically the same, site.

A crest-stage gage is a deviee which will register the peak stage occurring between inspections of the gage. A stage-discharge relation for each gage is developed from discharge measurements made by indirect measurements of peak flow or by current meter. The date of the maximum discharge is not always certain, but is usually determined by comparison with nearby continuous- record stations, weather records, or local inquiry. Only the maximum discharge for each water year is given. In- formation on sorne lower floods may have been obtained, but is not published herein. The. years given in the period of record represent water years for which the annual maximum has been determined. · Station No. 15054500 15057500 15081490 15081890 15086900 15087250 15087585 15087595 15108250 15108290 a Unknown.

The reach is 1.8 mi (2.9 km) in length and extends from the mouth of an unnamed tributary stream draining the Godwin Glacier basin to the mouth at tidewater. The measurements were made during a period of steady flow. Indicated gains or lasses may be substantia11y in error as affected by sma11 inaccuracies in open-channel measurements. Drainage Meas.

This is the on1y series of baseflow discharge measurements that has been made in the basin. The measurements are considered to represent summer base flow. Weather re~ords at Beluga, located 25 mi south- east of the basin, show that no precipitation occurred for seven days prior to the measurements. Streamflow at the nearest recording gaging station, Chuitna River near Tyonek (15294450), had been in a recession for four days since a minor peak on August 20. The measurements are listed in orde.r proceeding downstream, and each tributary is inserted in the arder in which it enters the main stream.
