QUANTITY AND QUALITY OP SURFACE WATERS OP ALASKA, 1960

SCOPE OP WORK

This volume contains results of measurements of the flow and the chemical anl physical 

quality of streams In the State of Alaska during the water year ending Septembe- 30, 1960. 

Since the beginning of stream-gaging work In Alaska In 1906, records of flow of streams 

and ditches have been obtained at about 340 gaging stations for periods ranging from a 

few months to 40 years. On September 30, 1960, the Geological Survey was maintaining 

75 gaging stations. Discharge measurements only were made at many other points in the 

1960 water year; these are published near the end of the report.

Prior to 1948, records of chemical and physical composition of surface waters In Alaska 

consisted of a few turbidity measurements of the Copper River near Copper Cente", in 1913, 

and chemical analyses of some surface waters of the Seward Peninsula, in 1914, of Yukon 

River basin, in 1915, and of the Yukon River at Anvlk, 1915 to 1916. In 1948 a continuing 

chemical-quality program was started by the Geological Survey. Several miscellaneous 

samples were collected and analyzed that year, and regular sampling stations we-*e established In'1949. During the 1960 water year records of chemical composition of surface 

waters were obtained at about 63 sites including 10 sites at which dally samples were collected during the open-water period. Sediment records were obtained at 16 sites during the 

"same period.

COOPERATION

Assistance In the form of funds or services was given by the Corps of Engineers, 

Department of Army, in collecting streamflow records published herein for nine gaging 

stations.

Assistance was also furnished by the Bureau of Reclamation of the United States Department of the Interior in the operation of three gaging stations.

The Alaska Department of Pish and Game cooperated in financing the operation of four 

gaging stations.

The Alaska Department of Natural Resources cooperated in financing the operation of one 

gaging station.

The Chugach Electric Association financed the operation of two gaging stations.

The Alaska Department of Health and Welfare cooperated In financing the operation of 

three gaging stations.

DIVISION OP WORK

The stream-gaging work was done by the Water Resources Division of the Geolcgieal Survey under the direction of the personnel shown in the preface. The streamflow data were 

collected and prepared for publication in the Surface Water Branch district office, the 

address of which Is 311 Fifth Street School Building, Juneau.

The collection of samples for chemical and suspended sediment analyses and ratertemperature measurements was under the direction of personnel of Quality of Water Branch 

assisted by the Surface Water Branch. Chemical and sediment analyses, computation of 

data, and preparation of records was done by the Quality of Water district office, Palmer, 

Alaska.
2 SURFACE WATER SUPPLY, 1960, ALASKA

Information of a more detailed nature than that published for most of th3 gaging stations or sampling stations given in this report is on file in the district offices. Provisional records of discharge prior to publication and other unpublished data concerning 

the records may usually be obtained from the district offices.

DEFINITION OF TERMS AND ABBREVIATIONS

The terms of streamflow and other hydrologic data, as used in this report, are defined 

as follows:

Gaging station is a particular site on a stream, canal, lake, or reservoir where systematic observations of gage height or discharge are obtained. When used in connection with 

a discharge record, the term is applied herein only to those gaging stations where a continuous record of discharge is obtained.

Cubic foot per second (cfs) is the rate of discharge of a stream whose channel is 

1 square foot in cross-sectional area and whose average velocity is 1 foot per second.

Cubic feet per second per square mile (cfsm) is the average number of cu^ic feet of 

water flowing per second from each square mile of area drained, assuming thit the runoff 

is distributed uniformly in time and area.

Runoff in inches (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.

Acre-foot (ac-ft) is the quantity of water required to cover an acre to the depth of 

1 foot and is equivalent to 43,560 cubic feet.

Cfs-day is the volume of water represented by a flow of 1 cubic foot per second for 

24 hours. It is equivalent to 86,400 cubic feet, 1.983471 acre-feet, or 646,317 gallons, 

and represents a runoff of 0.0372 inch from 1 square mile.

Stage-discharge relation is the relation between gage height and the amount of water 

flowing in a channel, expressed as volume per unit of time.

Control designates a feature downstream from the gage that determines the stagedischarge relation at the gage. This feature may be a natural constriction of the channel, 

a long reach of the channel, or an artificial structure.

The drainage are a of a stream at a specified location is that area, measured in a horizontal plane, which is so enclosed by a topographic divide that direct surface runoff from 

precipitation normally would drain by gravity into the river above the specified point. 

Figures of drainage area given herein include all closed basins, or noncontributing areas, 

within the area unless otherwise noted.

WSP is used as an abbreviation for "Water-Supply Paper" in references to previously 

published reports.

Part per million (ppm) is a unit weight of constituent in a million unit weights of 

solution. The unit has a slightly different meaning when applied to sedimert concentrations. A part per million of sediment is computed as one million times the ratio of the 

weight of sediment to? the weight of water-sediment mixture.

Hardness as CaC03 is the calcium and magnesium expressed as an equivalent amount of 

calcium carbonate.

Carbonate hardness is the hardness caused by calcium and magnesium equivalent to the 

carbonate and bicarbonate.

Noncarbonate hardness is the hardness caused by calcium and magnesium in excess of the 

carbonate hardness.
EXPLANATION OP DATA 3

Particle-size analyses are expressed In percentages finer than Indicated sizes In 

millimeters. The size classification used In this report is that recommended by the 

American Geophysical Union Subcommittee on sediment terminology.1

Specific conductance (micromhos per centimeter at 25"C) is one million times the reciprocal of specific resistance, at 25°C. Specific resistance is the resistance in ohms of 

a column of water 1 cm long and 1 square cm in cross section.

Suspended sediment or suspended load Is sediment that moves In suspension in water and 

is maintained in suspension by the upward components of turbulent currents or as a colloid. 

Dally sediment loads are expressed in tons per day, and except for subdivided days are 

usually obtained by multiplying dally mean sediment concentration In parts per million by 

the daily mean discharge, and the appropriate conversion factor, normally 0.0097.

pH is the negative logarithm of the hydrogen-ion concentration expressed In grams-moles 

per liter. However, when determined with a pH meter, which is the procedure normally used 

in Geological Survey laboratories, pH is an expression of the hydrogen-ion activity or the 

effective hydrogen-ion concentration.

DOWNSTREAM ORDER AND STATION NUMBERS

Gaging and sampling stations in this report are listed in a downstream direction along 

the main stem. All stations on a tributary entering above a main-stem station are listed 

before that station. If a tributary enters between two main-stem stations, it is listed 

between them. A similar order Is followed in listing stations on first rank, second rank, 

and other ranks of tributaries. To indicate the rank of any tributary on which a gaging 

or sampling station is situated and the stream to which it is Immediately tributary, each 

Indention in the listing of stations in the table of contents of this report mpresents 

one rank. This downstream order and system of indention show which gaging or sampling 

stations are on tributaries between any two stations on a main stem and the rank of the 

tributary on which each station Is situated.

As an added means of identification, each gaging station and sampling station has been 

assigned a station number. The numbers have been assigned in the same downstream order 

used in this report. Saps are left in the numbers to allow for new stations that may be 

established; hence the numbers are not consecutive. In this report the station number is 

shown Just to the left of the station name.

EXPLANATION OP DATA 

SURFACE WATER

The base data collected at gaging stations consist of records of stage and measurements 

of discharge. 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. The records of stage are obtained either from direct readings on a nonrecording gage or from a water-stage recorder that gives a continuous record of fluctuations. 

Measurements of discharge are made with a current meter by the general methods adopted by 

the Geological Survey on the basis of experience in stream gaging since 1888. These 

methods are described in Water-Supply Paper 888 and are also outlined in standard textbooks 

on the measurement of stream discharge.

Trans., V. Z8, p. 937.
4 SURFACE WATER SUPPLY, 1960, ALASKA

Rating tables giving the discharge for any stage are prepared from stage-dischargerelation curves defined by discharge measurements. If extensions to the rating curves are 

necessary to define the extremes of discharge, 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, and by other methods), velocity-area studies, and 

logarithmic plotting. The application of the daily mean gage height to those rating 

tables gives the daily mean discharge, from which the monthly and the yearly mean discharge are computed. 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 determined by the shifting-control method, in which correction factors based 

on individual discharge measurements and notes by engineers and observers are used in 

applying the gage heights to the rating tables. 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 discharge is computed by what is essentially the shifting-control 

method.

At many gaging stations in Alaska the stage-discharge relation is affected by ice 

during the winter, and it becomes impossible to compute the discharge in the usual manner, 

Discharge for periods of ice effect is computed on the basis of the gage-height record and 

occasional winter discharge measurements, consideration being given to the available information on temperature and precipitation, notes by gage observers and engineers, and 

comparable records of discharge for other stations in the same or nearby basins. If the 

stage-discharge relation is affected by ice, this information is given in a note to the 

table. No mention is made of occasional (Jays of ice effect if the degree of accuracy of 

daily records is not changed.

The streamflow data presented herein comprise a description of the station and a table 

showing the daily discharge and the monthly and yearly discharge of the stream. Records 

are published on basis of the water year which begins on October 1 and ends on September 30.

The description of the station gives the location, drainage area, records available, 

type and history of gages, average discharge, extremes of discharge, general remarks, and 

notations of revisions of the previously published record. The location of the gaging 

station and the drainage area are obtained from the most accurate maps available. Under 

"Records available" are given the periods for which there are published records generally 

equivalent to those at the present site. Under "Gage" are given the type of gage currently 

in use and the datum of the present gage above mean sea level, and a condensed history of 

the types, locations, and datums of previous gages used during the period of records 

available. Under "Average discharge" is given the average discharge for the number of 

years indicated. It is not given for stations having fewer than five complete years of 

record or for stations where changes in water development during the period of record 

cause the figure to have little significance. Under "Extremes" are given the maximum discharge and gage height; the minimum discharge if there is little or no regulation; the 

minimum daily discharge if there is extensive regulation (also the minimur discharge if 

useful); and the minimum gage height (unless it is of no importance). In the first paragraph the data given are for the complete current year unless otherwise specified. In the 

second paragraph the data given are for the periods of record within the calendar year 

dates in the heading (not necessarily those for the complete years indicated by the heading 

dates). Reliable information concerning major floods that have occurred cutside the period
EXPLANATION OF DATA 5

of record is given In the third or last paragraph under "Extremes." Unless ott^rwise qualified, the maximum discharge corresponds to the crest stage obtained by use of a waterstage recorder, a crest-stage gage, or a nonrecordlng gage read at the time of the crest. 

If the maximum gage height did not occur at the same time as the maximum discharge, It Is 

given separately. Information pertaining to the accuracy of the records and conditions 

which affect the natural flow at the gaging station Is given under "Remarks."

Previously published records of some stations have been found to be In error on the 

basis of data or Information later obtained. Revisions of such records are usually published In a subsequent report. In order to make It easier to find such revised records, 

a paragraph headed "Revisions (water years}" has been added to the description of all stations for which revised records have been published. In this paragraph are listed the 

reports In which revisions of dally discharge 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, 1933 stands for the water year October 1, 1932, to 

September 30, 1933. If no dally, monthly, or annual figures of discharge are concerned In 

the revision, that fact Is brought out by notations after the year dates as follows: 

"(M)" means that only the Instantaneous maximum discharge was revised; "(m)" tYat only the 

Instantaneous minimum was revised; and "(P)" that only peak discharges were revised. For 

stations in Alaska, however, monthly discharge for all stations prior to October 1950, 

were published in Water-Supply Paper 1372. Revisions of many monthly discharges as well as 

of previously published daily discharges were included in that report. The periods for 

which monthly discharge only is available and published in Water-Supply Paper 1372, are 

noted in the "Records available" paragraph. Therefore, the years for which revisions of 

monthly discharge only were made are not indicated under the "Revisions (water years)" 

paragraph. 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 the 

drainage 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.

For stations equipped with water-stage recorders, except those on streams subject to 

sudden or rapid fluctuation, the daily table gives the discharge corresponding to the dally 

mean gage height. For stations subject to such fluctuation the daily mean gage height may 

not indicate the true daily mean discharge, which must be obtained by averaging the discharge for parts of the day. For stations equipped with nonrecording gages, the table of 

daily discharge gives the discharge corresponding to once-daily readings of the gage, or to 

the mean of twice-daily readings, or to the mean gage height determined from gfge-height 

graphs based on gage readings. For periods of rapidly changing stage, the dally mean discharge is determined from gage-height graphs based on gage readings, the frequency of which 

is stated in the station description.

In the table of daily discharge, the figures for the maximum day and the mirimum day 

for each month are underlined. If the figure is repeated, It Is underlined only on the 

first day of its occurrence.

In the monthly summary below the daily table, the line headed "Total" gives the sum of 

the daily figures; it is the total cfs-days for the month. The line headed "Mean" gives 

the average flow in cubic feet per second during the month. Discharge for the month may be
6 SURFACE WATER SUPPLY, 1960, ALASKA

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 of cubic feet per 

second per square mile and runoff in inches are omitted if the drainage area includes 

large noncontributing areas, or if the average annual rainfall over the drainage basin is 

usually less than 20 inches.

In the yearly summary below the monthly summary, the figures of maximum are the maximum 

daily discharges, not the momentary discharges when the water was at crest stage. Likewise, the minimums in this summary are the minimum daily discharges.

Peak discharges and the times of their occurrence and corresponding gage heights of 

most stations are listed below the table of daily and monthly discharge. All independent 

peaks above the selected base are given. The base discharge, which is given in parentheses, is selected so that an average of about three peaks a year will be presented. Peak 

discharges are not published for canals, ditches, drains, or for any stream for which the 

peaks are subject to substantial control by man.

Footnotes to the table of daily discharge indicate periods when discharge was computed 

or estimated by unusual or special methods during periods of no gage-height record and ice 

effect, or by other effects that reduce the degree of accuracy of the records. Days on 

which discharge measurements were made are indicated by asterisk and footnote unless they 

were made at frequent regular intervals, in which instance the general frequency of discharge measurements is given under "Remarks" in the station description.

QUALITY OF WATER

In general, samples for chemical analysis were collected daily at ten of the regular 

sampling stations during the open-water period, and periodically during the period of ice 

cover. For the daily stations analyses were made of 10-day composites of daily samples. 

Three composites were prepared each month by combining equal volumes of daily samples 

collected from the 1st to the 10th, from the llth to the 20th, and for the remainder of 

the month. Samples were collected less frequently at many other stations in Alaska.

Samples collected for chemical analysis were analyzed according to metlnds regularly 

used by the Geological Survey. The methods are essentially the same as or are modifications of methods described in authoritative publications, for mineral analysis of 

water. 1 ' 2

The values reported for dissolved solids are either calculated from determined constituents or are determined by evaporation of a clear sample of water to dryness and drying 

the residue for 1 hour at 180°C. Specific conductance is given for most of the analyses 

and was determined by means of a conductance bridge using a standard potassium chloride 

solution as reference.

The streamflow data are reported in two ways: For regular daily stations the daily 

mean discharge is reported, whereas values given for discharge in the tables of miscellaneous analyses are normally the discharge at the time the sample was collected.

Suspended-sediment samples were collected daily during the open-water season at five 

stations, and periodically at eight stations. Samples were collected periodically during 

periods of ice cover at all stations. Daily samples were collected with a US D-49 depthintegrating sampler from a fixed point at one vertical in the cross section.

2 Methods for collection and analyses of water samples ; U. S. Geological Survey Water-Supply 

Paper 1454, 1960.
ACCURACY OP FIELD DATA AND COMPUTED RESULTS 7

Depth-integrated samples at three or more verticals in the cross section were collected 

periodically at all sediment stations. Occasionally point-integrated samples were taken 

with a US P-46 sampler.

Sediment concentrations were determined by weighing the solid residue after filtration 

or evaporation of the samples. For stations where samples were collected periodically, 

the concentrations reported are instantaneous concentrations or concentration of composites of several samples. For regular daily stations, daily mean concentrations were obtained for the periods during which samples were taken by plotting the instantaneous 

concentration on a copy of the gage-height-recorder chart. The plotted concentrations 

were connected by a continuous curve. Daily mean concentrations were estimated from the 

graph. Footnotes to daily values in the tables are used to indicate methods of 

computation.

In addition to sediment concentrations and loads, records of particle size are reported 

also for most of the sediment stations. Generally particle size was determined by a combination of sieve analysis and bottom-withdrawal tube analysis (U. S. Inter-agency, 1943). 

Sizes larger than 0.062 mm (sand-size) were determined by sieve analysis and fiose smaller 

than 0.062 mm were determined by bottom-withdrawal tube or pipette analysis. Native or 

distilled water, as noted in the tables of analyses, was used as the settling medium. 

Usually distilled water with a dispersing agent was used. Results obtained with distilled 

water and a dispersing agent as a settling medium approximate the ultimate particle size 

of the finer fractions, whereas results obtained with native water as the settling medium 

more nearly simulate the particle size existing in the stream.

For most daily stations, water temperatures were obtained at the time the samples for 

chemical quality were collected. Where practicable, the water temperatures at a station 

were determined at about the same time each day in order to minimize diurnal variation of 

temperature. The thermometer used for temperature determinations was accurate to plus or 

minus 0.5°F.

The description of the station Includes a statement giving the periods for which there 

are published records of water quality.

ACCURACY OF FIELD DATA AND COMPUTED RESULTS

The accuracy of streamflow data depends primarily on (1) the stability of the stagedischarge relation or, if the control is unstable, the frequency of discharge measurements, and (2) the accuracy of observations of stage, measurements of dlscharfe, and interpretation of records.

The station description states the degree of accuracy of the discharge records. 

"Excellent" indicates that, in general, the error in the daily records is believed to be 

less than 5 percent; "good," less than 10 percent; "fair," less than 15 percert; and 

"poor," probably more than 15 percent. The records of monthly and yearly mean discharge 

and runoff are, in general, more nearly accurate than the daily records.

Figures of cubic feet per second per square mile and runoff in inches are published 

only for stations in southeastern Alaska; they are not published for stations in the rest 

of the State, because the annual precipitation is generally less than 20 inch3s. Discharge at some stations varies widely due to great differences in precipitation not only 

between sections of the State, but also at different elevations in the same areas. 

Generally speaking, annual precipitation is much greater in southeastern Alaska and along
8 SURFACE WATER SUPPLY, I960, ALASKA

the coast to Seward than in the rest of the State. Even In southeastern Alaska annual 

precipitation may range from about 25 inches in the vicinity of Skagway in the northern 

part to about 150 inches near Ketchikan in the southern part, and may be as high as 

180 inches at the southern tip of Baranof Island, all measured at or near sea level. However, precipitation increases with altitude, reaching a maximum at about 4,000 feet elevation. Consequently, runoff in inches as measured at low elevations on streams draining 

mountainous areas often totals nearly twice the precipitation measured at or near sea 

level in the same drainage basin. At nearly every gaging station in southeastern Alaska 

the measured annual runoff in inches exceeds the annual precipitation as measured at the 

nearest Weather Bureau station.

PUBLICATIONS

A compilation of records of streamflow in Alaska through September 195C has been published as WSP 1372. Records prior to 1946 were published in Geological Survey bulletins 

or water-supply papers or in reports of other agencies. Summary tables ir WSP 1372 indicate the reports in which this data was originally published. In some cases the earlier 

reports contain more detailed information than is published in WSP 1372. That report 

contains a summary of monthly and annual discharges through September 194E for all previously published records as well as records of daily and monthly discharge for the years 

1946-50, which had not been published previously. All records prior to 1946 were reexamined and revised where warranted. Estimates of discharge were made to fill short gaps 

whenever practical.

Records of daily discharge and records of chemical quality, water temperatures, and 

suspended sediment from 1946 to date have been published in water-supply papers as shown 

in the following list. The data for any particular gaging station or sampling station 

will, in general, be found in the reports covering the years during which the station was 

maintained.

The reports referred to above contain, in addition to records of daily discharge at 

gaging stations, the results of discharge measurements at many points other than regular 

gaging stations.

Geological Survey reports containing data on quality of surface waters in Alaska prior 

to 1948 include the following:

at datum 1.4 ft higher. June 2 to Nov. 30, 1952, water-stage recorder at same site 

and datum.

Average discharge.--5 years, 38,250 cfs (27,690,000 acre-ft per year).

Extremes.--Maximum discharge during year, 169,000 cfs July 27 (gage height, 22.62 ft); 

minimum not determined.

1950, 1952, 1955-60: Maximum discharge recorded, 172,000 cfs June 10, 1958 (gage 

height, 22.52 ft); maximum gage height recorded, that of July 27, 1960; minimum not 

determined.

Maximum stage known since 1950, 28.3 ft, in July 1951, at present datum, from 

floodmarks (discharge, 220,000 cfs).

Remarks Records fair except those for periods of ice effect or no gage-height record, 

which are poor. Some diurnal fluctuation caused by glacier melt at the source.

Creek, 0.3 mile upstream from Alaska Railroad bridge, 1 mile north of Gold Creek railroad station, and 1.7 miles downstream from Indian River.

Drainage area.--6,160 sq mi, approximately (includes that of Gold Creek).

Records available.--Discharge: August 1949 to September 1960.

Chemical analyses: May 1951 to October 1952, October to November 1953, June to September 1955, June 1956, January to September 1957.

Water temperatures: June to September 1957.

Sediment records: April to September 1952 and June to September 1957 (daily); May 

1953 to August 1956 (periodic, summer months only).

Gage. Water-stage recorder. Datum of gage is 676.50 ft above mean sea level. Prior to 

June 6, 1957, wire-weight gage at site 0.3 mile downstream at same datum.

Average discharge.--11 years, 9,841 cfs (7,125,000 acre-ft per year).

Extremes.--Maximum discharge recorded during year, 41,900 cfs Sept. 13 (gage height, 14.45 

ft); maximum gage height, 18.23 ft, from floodmsrks (ice jam); minimum discharge not 

determined.

1949-60: Maximum discharge, 62,300 cfs Aug. 25, 1959 (gage height, 15.42 ft); maximum gage height observed, 24.48 ft May 10, 1954 (ice jam), site then in use; minimum 

discharge not determined.

Flood in May 1919 reached a stage of 19.2 ft, result of ice jam, from information by 

Bureau of Reclamation.

Remarks. Records fair except those for periods of ice effect or no gage-height record, 

which are poor. Large diurnal fluctuation cfaused by glacier melt at source.
