Abstract (Limit: 200 words) Water resources data for the 198:~ water year for Alaska consists of records of stage, discharge, and water quality of streams; stage and water quality of lakes; and water levels and ··rater quality in wells and springs. This report contains discharge records i.)r 108 gaging stations; stage only record for 1 gaging station; water quality for 49 stations; and water levels for 28 observation wells. Also inc ~uded are 43 low-flow, 67 crest- stage, and 4f· water-quality partial-record s,tations. Additional water da.ta were collected at various sites, not, ~?.art of the systematic data collection program, and are published as miscellaneous measurements of discharge, lake stage, or water quality. These data r~present that part of the National Water Data System operated by the U.S. Geological Survey and cooperating State and Federal agencies in Alaska. 1-·--------------------~-----------------·--------------~-- 17. uocume~~ Analysis a.

This volume contains records for water discharge at 108 gaging; stations; stage only at 1 guging stationl water quality at 49 gaging stations; and water levels for 28 obser- vation wells. Also included are dat:a for 43 low-flow, 67 crest-stage, and 48 water-quality partial-record stations and 23 l!;!.kes. Additional 11tat:~r data were collected at various sites not involved in the systematic data-collection program and are published as miscellaneous measurements and analyses. These data represent that part g£ the National Water Data System operated by the U.S. Geologicat Survey and cooperating State and Federal agencies in Alaska. Records of discharge and stage of streams, stage of lakes, chemical qual.i.r.y, 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 related data were published in a five-year series of water-supply papers for 1961-65 and 1966-70 entitled, ''Surface Water Supply of the United States." Water-quality records were published in a water-supply 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 Levels 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, 604 South Pickett Street, Alexandria, Virginia 22304. For water years 1961 through 1970, streamflow data were released by the Geological Survey in annual reports on a State-boundary basis. Water-quality ~~cords for water.years 1964 through 1970 were similarly released either in separate reports or in conjunction with streamflow records. Beginning with the 1971 water year, water data for streamflow, water quality, and ground ~-1ater are published in official Survey reports on a State-boundary basis. These official Survey repurts 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 identified as "U.S. Geolog- ical Survey Water-Data Report AK-82-1." 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.

I t ~ ~ I J ! l t t l I I i 2 WATER RESOURCES DATA FOR ALASKA, 1982 HYDROLOGIC CONDITIONS Streamflot\' in Alaska for the 1982 water year was generally in the normal :range. Flow at about 15 percent of the long-t~rm gaging stations (those with 10 or more years of record) was deficient (in the lowest 25 percent for the period of record). These stations v1ere mainly in Southeast Alaska. ·Runoff was the second lowest of record for a water year in Harding River near Hrangell, Mendenhall River near Juneau, and Fish Creek near Ketchikan which have 31, 17, and 64 years of record respectively. Flow was excessive (in the highest 25 percent for the period of record) at about 25 percent of the long-term gaging stations. These stations '"ere scattered throughout western Alaska. The discharg-e for the 1982 water year was the highest of record in the Kuparuk and Putuligayuk Rivers near Deadhorse on the Arctic Slope which have 11 and 10 years of record, respec- tively. Streams in Southeastern Alaska generally had below normal or deficient flows during October 1981. Storms in November resulted in above normal or excessive streamflows. Generally, runoff was deficient during February through April. Most streams in Southeast Alaska had an above normal or excessive period of streamflow during May or Juna. After June, the runoff was generally below normal or deficient. Streamflow during August was the lowest of record in Harding River. The tt\'o notable seasonal streamflow trends in South-central Alaska were that the runoff was deficient or below normal during the snowmelt period and excessive during September. September flows were the highest of record at the long-term stations: Bradley, Anchor, and Ninilchik Rivers in. the lower Kenai Peninsula, Campbell Creek at Anchorage, and Skwentna River northwest of Anchorage. Many other shorter term stations had record September flows. Notable peak flows {the highest for the period of record) occurred at the gage on Chuitna River near Tyonek and at the crest-stage gage on Spruce Creek near Seward. The period of higher than normal September precipitation affected runoff in other streams in western Alaska such as Myrtle Creek near Kodiak, Nuyakuk River near Dillingham, and Koyukuk River near Hughes. ~bese streams also experienced above normal flows in June and July. The only discernable seasonal trend at the long-term stations in the Tanana River basin was that runoff in June was above normal or excessive because of widespread general rains in the last half of the month. Streamflow in June was the highest and second highest of record, respectively, at the two gaging stations Qn the Arctic Slope near Deadhorse on the Kuparuk and Putuligayuk Rivers. Monthly and annual mean discharge for 1982 is compared with median monthly and annual discharge for the period of record in figure 3 at six represent~tive gaging stations ~hroughout the state. DEFINITION OF TERMS Terms related to streamflow, water-quality, and other hydrologic data, as used in this report, are defined as follows. See aL~o the table for converting English UP-its to International System of units (SI) on the inside of the back cover. Acre-foo~ (AC-FT, acre-ft) is the quantity of water required to cover 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. Aguit~ is a geologic formation, group of r-..;rmations, or part of a formation that contains sufficient saturated permeable material to yield signif:i cant quantities of water to wells c. '1d springs. Artesian means confined and is used to describe a well in which the water level stands above the top of tne aquifer, tapped by the well. A flowing artesian well is one in which the water level is above the land surface. Bac!:.~ria are microscopic unicellular organisms, typically spherical, rodlike, or spiral and threadlike in shape often clumped into colonies. Some bacteria cause disease, others perform an essential role in nature in the recycling of materials; for exwple, by decomposing organic matter into a form available for reuse by plants. Total.coliform bacteri~ are a particular group of bacteria that are used as indicators of possible sewage pollution. They are characterized as aerobic or facultative anaerobic, gram- negative, nonspore-forming, rod-shaped bacter~a which ferment lactose with gas formation within aB hours at 35 °C. In the laboratory these bacteria ar.e defined as all the organisms which produce colonies with a golden-green metallic sheen within 24 hours when incubated at 35°C ± 1. 0°C on M-Endo medium (nutrient medium for bacterial growth). Their concentrations are eA~ressed as numb~r of colonies per 100 milliliters (mL) of sample. Fecal coliform bacteria are bacteria that are present in th& intestine or feces of warm- blooded animals. 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 ± 0.2°C on M-FC medium (nutrient medium for bacterial growth). Their con- centrations are expressed as number of colonies per 100 mL of sample. Feca!__streptococcal bacteria are bacteria found also in the intes.tine of warmblooded anima~ ThPir presence in water is considered to verify fecal polluti·on. 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 org<:misms which produce red or pink colonies within 48 hours at 35°C ± l.Ooc on M-enterrococcus medium (nutrient medium for bacte- rial growth). Their concentrations are expressed as number .:f colonies per 100 mL of sample. ~ ; I ~ " ,, I !! ~ 6 I ;I ~( I l • " .J >i ·~ ., i~ ~! ~· .. :l ;\ 1: ;fi 'j ~ ,. ,, ~; ,l I ., ~ t ,, ' ·t tl ,, 'I lj 1 !i \I [I :~ I ~ ,. lJ " ::·; !

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 treatrr.ent 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 digestion procedures would be required of all laboratories performing such analyses because l:!t£ferent digestion procedures are likely to produce different analytical results. Total in bottOI~ material is the total amount of a given constituent in a representative sample of bottom material. Th5 s term is used only when the analytical procedure e.ssures measurement 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 analytical methodology used, is required to judge when the results should be reported as utotal in bottom material". Cells/volume refers t'? the number of cells of any organism which is counted by using a micro- scope and grid or counting cell. Many planktonic organisms are multicelled and are counted accord- ing to the number of contained cells per sample, usually milliliters or liters (L). Cfs-day is the volume of water repr~sented ~y a flow of 1 cubic foot per second for 24 hours. It is equivalent to 86,400 cubic feet, approximt.taly 1.983~ acre-feet, or about 646,000 gallons or 2,447 cubic meters. Chlorouhyll refers to the green pigments of plants. Chloropl"J•ll ~ and b are the two most common green pigments in plants. Color unit is produced by one milligram per liter of platinum in the form of the chloro- platinate ion.. Color is expressed in units of the platinum-cobalt scale. Control designates a feature downstream from the gage that determines the st3.ge-discharge relation at the ga¥e. This feature may be a natural constriction of the channel, an artificial structure, or a unL.orm 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 flc.""'ing per second from each square mile of area drained, assuming that the runoff is distributed unifo~mly in time and area. Cubic foot per second (FTl/S, or ftl/s) is the rate of discharge representing a volume of 1 cubic foot passing a given 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 . Dischar~ is the volume of water (or more ·;Jroadly, 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 specific 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 membrane filter. This is a convenient operational definition used by Federal agencies that collect water data. Determinations of "dissolved" constituents are made on subsamples of the filtrate. Drainage area of a stream at a specific location is that area, measured in a horizontal plane, enclosed by a topographic divide from whiclc_ direct surface runoff from precipitation nor111ally 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. Gage h~~ght (G.H.) is the water-surface elevation referred to some arbitrary gage datu:n. Gage height is o ten used interchangeably with the general term "stage, 11 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 where systematic observations of hydro- logic 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 (principally calcium and magnesium) and is expressed as equivalent calcium carbonate (CaC0 3 ), Hydrologic unit is a geographic area representing part or all of a surface drainage basin or distinct hydrologic feature as delineated by the Office of \-later Data Coordination on the State Hydrologic Unit Maps; each hydrologic unit is identified by an 8-digit number. Micrograms per liter (UG/I., ug/L) is a unit expressing the concentration of chemical constitu- ents in solution as mass (micrograms) of solute per unit volume (liter) of water. One thousand micrograms per liter is equivalent to one milligram per liter. ·,;i ~ . , ,t ,l ., i' ·, '1 ,r \ n ·' d ,i 4 WATER RESOURCES DATA FOR ALASKA, 1982 Milligrams per liter (MG/L, mg/L) is a unit for expressing the concentration of chemical con- stituents in soh1tion. 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 Verticdl Datum of 1929 (NGVD) is a geodetic datum derived from a general adjustment of the first order 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. c~.lthough the datum was derived from the average sea level over a period of many years at 26 tide stations along tht! Atlantic, Gulf of Mexkco, and Pacific Coasts, it does not necessarily represent local mean sea level at any particular place. Partial-record station is a particular sLte where limited streamflow or water-quality data are collected systematically over a period of years for use in hydrologic analyr-es. Particle size is the diameter, 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 tul:~) determine fall diamete·c of particles in e:Lther 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: Classificat;:ion Clay .....•.... Silt .....••.•. Sand .•......•. Gravel ......•• Size (mm) 0.00024 - • 004 • 062 2.0 0.004 .062 2.0 64.0 Method of analysis Sedj.mentation . Sedimentation . Sedimentation or sieve. Sieve. The particle .. size distribution given in this report are not necessad ly representative of all particles in transport in the stream. Most of the organic material is 't'emoved 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. Pesticides are chemical compounds used to control undesirable plants and animals. Major cate- gories of pesticides include insecticides, miticides, fungicides, herbicides, and rodenticidcs. Insecticides and herbicides, which control insects and plants respectively, are the tt-70 categories. reported. Picocuri (PC, pCi) is one trillionth (1 x 1012 ) of the amount of radioa1_1(jivity represented by a curie (Ci). A curie is the amount of radioactivity that yields 3. 7 x 10 radioactive disinte- grations pe~ second. A picocurie yields 2.22 dpm ~disintegrations per minute). Polychlorinated biphenyls (PCBs) are industrial chemicals that are mixtures of chlorinated biphenyl compounds having various percentages o=: chlorine. They are similar in structure to organo·· chlorine insecticides. Runoff in inches (IN, in) shows the depth to which the drainage area would be covered if all the runoff for a given time period were uniformly distributed on it. Sediment is solid material that originates mostly from disintegrated rocks ac~ ~s transported by, suspended in, or deposited from water; it includes chemical and biochemical precipitates and decomposed organic material such as humus. ~ne quantity, characteristics, and cause of the occur- rence of sediment in streams are influenced by environmental factors. Some major factors are degree of slope, length of slope, soil characteristics, land usage, and quantity and intensity of precipi- tation. 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. concentration of Suspended-sediment discharge (tons/day) is the rate at which dry weight of sediment passes a section of a stream or is the quantity of sediment, as measured by dry weight or volume. that is discha1. ~d in a given time. It is computed by multiplying discharge times mg/L t~mes 0.0027. Suspended-sediment load is quantity of suspended sediment passing a section in a speci- fied period. Total sediment discharge (tons/day) is the S";Im of the suspended-sediment discharge and the oedload discharge. It is the total quantity of sediment, as measured by dry weight or volume, that passes a section during a given time. Mean concentration is the time-weighted concentration of fw .. pemled sediment passing a stream section during a 24-hour day. Solute is any substance derived from the atmosphere, vegetation, soil, or rocks that is dis- solved in water. - l- l l l l L L L \VATER RESOURCES DATA FOR ALASKA, 1982 6 Specific conductance is a measure of the ability of a water to conduct an electrical current and is exp'!:essed in micromhos per centimeter at 25°C. Specific conductance is related to the type and concentration of ions in solution and can be used for approximating the dissolved-solids content in the water. Commonly, the concentration of dissolved solids (in milligrams per liter) is about 65 percent of the specific 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 time, flowing in a channel. Streamfiow is the discharge that occurs in a natural channel. Although the term "discharge" can b-e applied to the flow of a canal, the word "streamflolV'11 uniquely describes the discharge in a surface stream course. The term "streamflow" is moT." general than "runoff" as str~amflow may be applied to discharge ~1ether or not it is affected by. ~version or regulation. Suspended, recoverable is th~ amount of a given constituent that is in solution after the part of. a representative water-suspended sediment sample that is retained on a 0.45 micromete" membrane £ilter 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 digeation 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 dif- ferent analytical results. . Determinations of "suspended, recoverable" constituenta 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 ~erable concentrations of the constituent. Suspended, total is the total amount of a given constituent in the part of a representative water-suspended sediment sample that is retained on a 0.45 micrometer membrane filter. This term is used only when the analytical procedure assures measurement of at least 95 percent of the con- stituent determined. A knowle:dge of the expected form of the constituent in the sample, as well as the analytical methodology U§§d, · . required to determine when the results should be reported as llsuspended, 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 (l' dissolved and (2) ~al concentratio~s of the constituent. Tons per acre-foot indicates the d=y weight of dissolved sol~ds in 1 acre-foot of water. It ir computed by multiplying the concentration :l,n milligrams per liter oy 0.00136. 'ron~~ is the quantity of a substance in solution or suspension that passes a strean seetionourJ.ng a 24-hom: day. Total, reco\erable is the amount of a given constituent that is in solution after a representa- tive water-Sl\Spendedsediment sample has been digested by a method (usually using a dilute add solution) that results in dissolution of only readily soluble substances. Complete dissolution cf all particula'C.:L' m~t:t~r is not achieved by the digestion treatment, and thus the determinat:ion repr£ .. se:J.ts something less than the "total" amount (that is, less than 95 percent) of the constitue11t pre-sent ir the dissolved and suspended phases of the sample. To achieve comparability nf analytical data, equivalent digestion procedures wc.uld be required of all laboratories performi1:g such analyses because different digestion procedures are likely to produce different analytic~.l results. T'Jtal is the. total amount of a given constituent in a representative water-suspended sedimert sample, regardless of the constituent's physical or chemical form. This term is used only when tbe analytical procedure assures measurement of at least 95 percent of the constituent present in both the dissolved and suspended phases of the sample. A knowledge of the expected form of the con- stituent in the sample, as well as the analyti~al methodolo?,y used, is required to judge when th~ results should be reported as "total''. (Note that the word 'total" does double duty here, indicat- ing t.;:t-h that the sample consists of 1 watcr-suspE::nded sediment mixture and that the analytical method determines all o£ the const1tuen~ in the sample.) HSP is used as an abbreviation for "Wl:l.te:::~Supply Paper" in references to previously publishe i reports:' DOWNSTREAH ORDER AND STATION NUMBER Since October 1, 1950, the or0~r of listing hydrologic-station records in Survey reports is ir a downstream direction along the main stream. All stations on a tributary entering upstream from ~ main-stream stati!!n are listed before that station. A station on a tributary that enters betweer two main-stream stations is li~ted between them. A similar order is followed in listing stations or. first rank, second rank, and other ranks of tr.ibutaries. The rank of any tributary on which a station !s situat~d with respect to the stream to which it is immediately tributary is indicated by an indention in a list o£ stations in the front of the xeport. Each indention represents one xank, This downstream. ordet and system of indention show which stations are on tributaries between any two stations and the rank of the tribut< ~y on which each station is situated. I 6 WATER RESOURCES DATA FOR ALASKA, 1982 . As an added means of identification, each hydrologic 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 nUinbers, 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 both types of stations. Wate1::-quality stations located at or near gaging stations or partial~record stations have the same number as the gaging o.r partial-record station. Gaps ,are left in the series of numbers to allow for new stations that may be established; hence, the numbers ar(! not consecutive. The: complete 8-digit number for each station, such as 15303600, which appears just to the left of the station nan1e, includes the 2-digit part number "15" plus the 6-di_git downstream vrder number "303600." NL'l1BERING SYSTEM FOR WELLS AND MISCELLANEOUS SITES TI1e 8-digit downstream order station numbers are not assigned to wells and miscellaneous sites where only random water-quality samples or discharge measurements are ta~en. The w~ll 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 geographic 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 ne~t 7 digits denote degrees, minutes, and seconds of longitude, and the last 2 digits (assigned sequentially) identify the wells or other sites within a 1-second grid.

SPECIAL NETWORKS AND PROGRAMS !{ydrol'!gic bencf.-ma:r'~_station is one that provides hydrologic data for a basin in which the hydrologic regimen willLi. aly be governed solely by natural conditions. Data cbllected at a bench- mark station may be ust'd -;v separate effects of natural from manmade changes in other basins which have been developed and in which the physiography, climate, and geology are similar to those in the undeveloped bench-mark basin. National stream-quality accounting network (NASQAN) is a data collection network designed by the U.S. Geological Survey to meet many of the information dP.mands of agencies or groups involved in national or regional wat~r-qualit7 planning and management. Both accounting and broad-scale moni- toring objectives have been incorporated into the network design. Areal configuration of the net- woi;k is based on river-basin accounting units (identified by 8-digit hydrologic-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 i~ streamflow and stream quality. Pesticide program is a network of regularly sampled water-quali.ty 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 a~e collected to be analyzed for radioisotopes. The streams that are sampled represent major drain- nge basins. EXPLANATION OF STAGE AND WATER-DISCHARGE RECORDS Collection and computation of data The ~ase data collacted at gaging st<'ltions consist of records of stage and measurements of discharge of streams and stage of lakes. 1~ addition, observations of factors affecting the st~ge­ discharge relation, weather records, and oth~r information are used to supplement base data in determining t~e daily flow. Records of stage are obtained from direct readings on a nonrecoroing gage or fran ~ Wqter-stage recorder that gives either a continuous graph of the fluctuations or a tape punch~d at selected time intervals. Measurements of discharge are made with a current meter, l l l l L. L_ WAT£R RESOURCES DATA .FOR ALASKA, 1982 7 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 stage are prepared from stage-discharge relation curves. If extensions to the rating curves are necessary to express dis- charge greater than measured, they are made on the basis of indirect measu:~;ements of peak discharge (such as slope-area or contracted-Qpening measurements 1 computation of flow over dams or weirs), step-backwater techniques, velocity-area studies, and logarithmic plotting. The daily mean disc- ha:~;ge is computed from gage heights1 and rating tables 1 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 continual change in the physical features that form the control, the daily mean discharge is computed by the .~hifting-control method, in whic'1 correction factors based on individual discharge measurelftent£ and notes by engineers and ob~~ervers are used in applying the gage heights to the :~;ating table~, I± the stage-discharge relation for a station is temporar.·Gy changed by the presence of aquatic. ,;t_,wt~t .,~ debris on the control, the daily mean discharge is computed by what is basically the shift, ,g.~~c.<.trol method. At mast stream-gaging stations i.n 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 to 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 some gaging stations there are periods when no gage-height record is obtained or the recorded gage height is so faulty that it cannot be used to computa daily discharge. This happens v.•hen the recorder is stopped for the winter or otherwise 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 stage, prior and subsequent records, discharge measurements, weather reco1:ds 1 and comparison with records for other stations in the same or nearby basins. The data in this report generally com:;>rise 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 Gnd yearly discharge is given. Tables of daily mean gage heights are included for some streamflow stations. Records are published for the water year 1 which begins on October 1 and ends on September 30. The description of the gaging stations gives the location, drainage are .. , period of record, notations of revisions of previously published re~ords, type and history of gages, general remarks, average discharge, and extremes of discharge. The location of the gaging station and the drainage are:a are obtained from th.a most accmrate maps available. Periods for which there are published recorrls for the present station or :Eor stations generally equivalent to the present one are given under "PERIOD OF RECORD." Previously pu~lishcd streamflow recv£ds of some stations have been found to be in error on the basis of data or information later c1btained. Revisions of such records are usually published along with the current :ecozds in one ~f the annual 0r compilation reports. In order to make it easier to find such revised records, a paragraph headed "REVISED RECORDS" has been added to the de-scription 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 i1: that report. In listing the watelr years only one nu!'lber 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 discharge was revised; "(m)" that only the instantaneous minimum was revisedi and "(P)" that only peak discharges were revised. If the drain- age araa has been revised, the report in which th.a revised figure was first published is given. It should be noted that for all atatiorts for which cubic feet per second per square mile and runoff in inches are published, a revision of the drainage area necessitates corresponding revision of all figures based on the drainage area. Revised figures l-;. cubic feet per second per square mile and runoff in inches resulting from a rc~visiCin of the drainage area only are usually not published in the annual series of reports. The type of gage currently in ~Se 1 the datum of the present gage refarred to National Geodetic Vertical Datum, and a condensed history of the types, locations 1 <:tnd datums of previous gages used during the period of record are give·n unde:~; "GAGE, 11 National Geodetic Vertical Datum is explained in 11 DEr'INXTION OF TERMS" on page 5. Information pertaining to the accuracy of the discharge reco1:ds and to conditions which affect the natural flow of the gaging static1n is given under 11REMARKS." The average discha:~;ge for the number of years indicated is given under "AVERAGE DISCHARGE"; It is not given for stations having fe~rer than 5 complete years of ~:ecord. Under "EXTREMES" are given fi.rst, the extrem~s for the period of record, second, information available outside the period of record, and last, those for the cun·er.t year. Unless otherwise qualified, the maximum discharge is the instantaneous maximum co:crespond:i.ng to the crest stage obtained by use of a water-stage recorder (graphic or digital), a crest-stage gag.e, or a nonrecording gagt~ read at the time of the crest. If the maximum gage height did not occur on the same day as the maximum dischar.ge, it is given separately. Similarly, the mini!llum is the insta11taneous minimum unless otherwise qualified. For some stations peale. discharges are listed with EXTREHES FOR THE CURRENT YEAR; if they are, all inrlependent peaks, includit1g the. ma:dmum for the year, above the selected base with the time of li l .; 'I I r------------ 8 WATER RESOURCES DATA FOR ALASKA, 1982 occurrence and corresponding eage height;; 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 anJ stream for which the peaks arc 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 minimums for these stations are published in a separate paragraph following the table of peaks. The daily table for stream-gaging stations gives the mean -:lischarge for each day and is by monthly an<! yearly summaries. In the monthly summary below the daily table, the line headed "TOTAL 11 gives the sum of the daily figures. The line headed "MEAN" gives tl:le ave~ ... ge flow i.:1 cubic feet_ per second during the month. The lines headed "MAX 11 and "MIN" give tbe rna~, •• 11um and minimum daily dis- charges, respectively, for the month. Discharge for the month also may be expressed in cubic feet per second per square mile (line headed "CFSM"), or in inches (line headed "IN"), or in acre-feet (line headed "AC-FT"). Figures for cubic feet per second per square mile and runoff in inches are omitted if there is extensive regulation or diversion, if the drainage area includes large noncon- tributing areas, or if most of the flow is from a spring. In the yearly summary below the monthly SQ~ary, the figures shown are the appropriate daily discharges for the calendar and water years. Footnotes :.:o 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, back\-later from various sources, or other unusual conditions. Periods of no gage-height record are indicated if tl:.e period is continuous for a month or more or in...:ludes the maxiwum discharge for the year. Periods of backwater from an unusual source of indefinite stage- 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 indicat~d. The methods used in computing dis- charge 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 d:!.scharge at crest-stage stations. The tables of partial-record stations are followed by a listing of discharge measurements made at sites other than continuous-record or partial-record stations. Occasioilally, a series of discharge measurements ace made within a short tim~ period to investigat:e 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 miscellaneous selected la:\es are tabulated also. Accuracy of field data and computed results The accuracy of ~treamflow data depends 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 "REHARKS" 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 shmvn to the nearest hundredth of a cubic foot per second for discharges of less than 1 ftl/s; to tenths between 1.0 and 10 ft 3 /s; to whole numbers between 10 and 1,000 ftl/s; and to 3 significant figures above 1,000 ft 3 /s. The number of significant figures used is based solely on the ma:;, . .titude of the figure. The same rounding rules apply to discharge figures l:i,sced for partial-1:ecorl stations. Discharge at many stations, as indicated o7 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 satis- factory 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 offices at Anchorage, Fairbanks, and Juneau for their areas of :responsibility. Also most gaging-station records are available in computel. -usable form and many statistical analyses have been made. Information on the availability of unpublished data or statistical analyses may be obtained from the district office. EXPLANATION OF WATER QUALI4Y 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 given immerliately following the discharge records at these stations. I H I i I ; ~ I i H <f \ T ~. ,~ ( i ilA' I ~\ ~~ ' i .IB, ~~ ' I l ;i\ jll ·--' j Ill ;, L WATER RESOURCES DATA FOR ALASKA, 1982 9 The descriptive hea,'i.ng for water-quality records gives the period of record for all water- quality data; the period ot ci .. :!.1;• record for parameters that are measured on a daily basis (specific conductance, pH, dissolved oxygen, water temperature, sediment discharge, etc.); extremes for the period of daily record; extremes for the current year; and general remarks. F~r 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 ground water. Water analysis Host methods for collecting and analyzing water samples are dese:ribed in the U.S. Geological Survey Techniques of '~ater-Resources Investigations listed on a following page. One sample can define adequately the water quality at a given time if the mixture of sol·.:.Ites throughout the stream cro£s section is homogeneous. However, the concentration of solutes at dif- ferent locations in the ~ross section may vary widely with different rates of water di.scharge, depending on the souzce 'Jf material aud the turbulence and mixing Ol. the stream. ?.;.:!:a streams must be sampled th1.:ough several vertical sections to obtain a representative sample".,':le.edc-1 for an accurate mean concentration and for use in calculating load. Chemical-quality data published in this report are considered to 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 sampling 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 (carbonp.te and bicarbonate.), the inconsistency is the result 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. 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. Some streams may be. affected by waste-heat discharges. At stations where recording instrumen·ts are used, maximum and minimum temperatures for each day are published. Sedim~ Suspended-sediment concentrations are determined from samples collected by using depth-inte- grating samplers. 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 ciet:rmine the mean concentration in the cro~s sections. During periods of rapidly changing flow or rapidly changing concentration, samples n1ay have been collected more frequently (twice daily or, in some instances, hourly). The published sediment discharges for days of rapidly changing flow or concentration were computed by the subdivided day method (time-discharge weighted average), Therefore, for those days ~Then the published sediment d~scharge 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 dis~harge, sediment concentrations observed imm~diately 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 ~1e stream crosb 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 GRIJUNJ-HATER L!:..IJEL RECORDS Collection o~ th~ data Only ground-water level data from a basic network of observation wells are published herein. This basic network consists of observation wells located in the most important aquifers, and there- fore the most significant data are obtained from the fewest wells. (See figure 1.) Each well is identified by means of (!) a 15-digit number that is based on latitude and longi- tude and (2) a local number that is provided for local needs. (See figure 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 I I ! ! ' ! I ! I ( l l ~ 1 l 1 l j 10 WATER RESOURCES DATA FOR ALASKA, 1982 well is 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 order subdivision. Each of these subdivisions is lettered ccunter-clockwise, from the northeast corner. Each well within th~ smalle:;t order of subdivision is then given a sequential number. Finally, each well within a section is assigned a sequential map numbe:JO using the last three digits. Thus, SB00601115BCAD1 indicated the Seward meridian (S), the northwest quadrant (B), township 6 north, range 11 west, sect~on 15; and the we~l is in the SE% of the NE% of the SW% of the Ni-1% of the section (BCAD). It was the first well in the 2.5 acre "D" subdivision assigned a sequen- tial 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 ?lotted 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 ::or continuity with older reports. The use of this number, for new wel/. sites, was discon- tinued ~n 1981. Therefore, the local number, for well sites established prior to 1981 is SB00601115BCAD1001 00114 and the number for new sites established beginning in 1981 is SB00601115BCAD1 001. Measurements are rn9de in many types of wells, under varying conditions of access and at dif- ferent temperatures; 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-level measurements in this report are given in feet referred to either National Geodetic Vertical Datum tNGVD) or land-surface datum (lsd). National Geodetic Vertical Datum is the datum plane on V1.1ich the national network of precise levels is based; land-surface datum is a datum plane that is approximately at land surface at e;:tch 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 (earn). Daily water levels are reported for a few wells that lilay 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 o£ several hundred feet or if an elec- tric water sensor must be used, the error in determining the absolute value of the total depth to water may be five or more hundredths of a foot. However, the error 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 ar~ given only to a tenth of a foot.

J I l DISCHARGh AT PARTIAL-RECORD STATIONS AND MISCELLANEOUS SITES 245 As the number of streams on which streamflolv information is likely to be desired far exceeds the. number of stream-gaging stations feasible to operate at one time, the Geological Survey collects limited stream-flow data at sites other than stream-gaging stations. When limited streamflow data are collected on a systematic basis over a period of years for use in hydrologic 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 low-flow or floodflow analyses, depending on the type of data collected. In addition, discharge ~easurements are made at other sites not included in the partial-record program. These measurements are generally made in times of drought or flood to give better. areal coverage to those events, Those measurements and others collected for some special reason are called measurements ac miscellaneous sites~ Records collected at partial-record 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. Discharge measurements made at miscellaneous sites for both low flo\! and high flow are given in a third table. Low-flow partial-record stations Measurements of streamflow in Alaska ·ade at low-flow partial-record stations are given in the following table. These measurements were made during per ... :.~ds of basa flow when streamflow is p:::imarily £rom ground-water storage. These measurements • when correlated with the simultaneous discharge of a nearby stream when continuous records are available, will give &. picture of the low-flow potentiality of a stream. For some stations, measurements made periodically through the year are also included. l'he column headed "Period of record" shows the w~:~ter years in which measurements were made at the same, or practically the same, site.

A crest-stage gage is a device 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 Qf 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 some 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.
