SCOPE OF WORK

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

quality of streams in the Territory of Alaska from October 1953 to September 1956. Since 

the beginning of stream-gaging work in Alaska in 1906, records of flow of streams and 

ditches have been obtained at about 310 gaging stations for periods ranging from a few 

months to 40 years. On Sept. 30, 1956, the Geological Survey was maintaining 61 gaging 

stations. Discharge measurements only were made at many other points during the 1954-56 

water years; 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 Center, 

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 Anvik, 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 

were established in 1949. During the period covered by this report records of chemical 

composition of surface waters were obtained at about 188 sites including 12 sites at which 

daily samples were collected during the open-water period. Sediment records were obtained 

at 18 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 12 gaging 

stations.

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

DIVISION OF WORK

The stream-gaging work was done by the Water Resources Division of the Geological Sur 

vey 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 117 Federal and Territorial Building, Juneau

The collection of samples for chemical and suspended sediment analyses and watertemperature 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.

Information of a more detailed nature than that published for most of the gaging stations or sampling stations given in this report is on file in the district offices shown 

above. 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: 

 

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 cubic feet of 

water flowing per second from each square mile of area drained. assuming that the runoff 

is distributed uniformly in time and area.

Runoff in inches is the depth to which an area would be covered if all the water draining from it in a given period were uniformly distributed on its surface. The term is used 

for comparing runoff with rainfall, which is also usually expressed in inches.

Acre-foot is the quantity of water required to cover an acre to the depth of 1 foot and 

is equivalent to 43,560 cubic feet. The term is commonly used in relation to storage for 

irrigat ion.

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 area 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" iri 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 sediment concentrations. A part per million of sediment is computed as one million times the ratio of the 

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

Hardness as CaCOs 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 th <# 

carbonate and bicarbonate.

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

carbonate hardness.

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.-'-

Specific conductance (micromohos 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.

Lane, E. W., et al., 1947, Report of the Subcommittee on Terminology: Am. Geophys. Union 

Trans., V. 28, p. 937.
EXPLANATION OF DATA J

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. 

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

usually obtained by multiplying daily mean sediment concentration in parts per million by 

the daily mean discharge, and the appropriate conversion factor, normally 0.0027.

p_H 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 OP LISTING GAGING AND SAMPLING STATIONS

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 represents 

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.

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 determing 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.

Rating tables giving the discharge for any stage are prepared from stage-discharge 

relation 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 

determinations of peak discharge (such as slope-area or contracted-opening determinations, 

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
4 SURFACE WATER SUPPLY, ALASKA, 1954-56

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-dischrge 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-dispharge relation is affected by ice, this information is given in a note to the 

table. No mention is made of occasional days 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 and runoff 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 for each water 

year 1954-56 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 minimum discharge if useful); and the minimum gage height (unless it is of no 

importance). In a summary paragraph are given the data 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 outside the period of record are given in a separate paragraph under "Extremes." 

Unless otherwise qualified, the maximum discharge corresponds to the crest stage obtained 

by use of a water-stage recorder, a crest-stage indicator, or a nonrecording 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 nave oeen 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 ordef 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
EXPLANATION OP DATA 5

reports in which revisions of daily 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 daily, 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)" that 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 

daily 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 

gage-height graphs based on gage readings. For periods of rapidly changing stage, the 

daily 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 minimum day 

for each month are underlined. If the figure is repeated, it is underlined only ori 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. Runoff for the month 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 hearted "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 minumums 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
6 SURFACE WATER SUPPLY, ALASKA. 1954-56

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 15 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 methods 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 value reported for dissolved solids is the residue on evaporation after drying at 

180°C for 1 hour. 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 mlscellarfcous analyses are discharge at the time the sample was collected. Footnotes are^used 

to indicate the latter.

Suspended-sediment samples were collected daily during the open-water season at 2 stations, and periodically at 16 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. Depthintegrated 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 most stations the concentrations reported are instantaneous concentrations or concentration of composites of several daily samples. Monthly 

sediment loads were estimated for the Susitna River at Gold Creek during the summer of 

1955 Daily mean concentrations were obtained for Nenana River at Healy and for Tanana 

River near Tanacross for the period during which daily 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. T-nter-agency, 1943). 

Sizes larger than 0.062 mm (sand-size) were determined "by sieve analys-is and those smaller 

than 0.062 mm were determined by bottom-withdrawal tuoe 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 gize 

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 wate'r 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°P.

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

are published records of water quality. Extremes for constituents, suspended sediment, 

and temperature are not given for regular stations owing to the short period of continuous 

records.

ACCURACY OP 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 discharge, 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 percent; 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 Territory, because the annual precipitation is generally less than 20 inches. Runoff varies widely in Alaska due to great differences in precipitation not only between 

sections of the Territory, but also at different elevations in the same areas. Generally 

speaking, annual precipitation is much greater in southeastern Alaska and along the coast 

to Seward than in the rest of the Territory. 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
8 SURFACE WATER SUPPLY, ALASKA, 1954-56

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 1950 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 in 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 1946 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.

Daily discharge records for water years 1951-53 have been published in WSP 1466. 

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.

SOUTHEASTERN ALASKA 21

Sheep Creek near Juneau

Location.--Lat 58°16'30", long 134°lb l 50", on right bank 0.3 mile upstream from diversion 

dam of Alaska-Juneau Gold Mining Co.'s Sheep Creek powerplant, 1 mile northeast of 

Thane, If miles upstream from mouth, and 4 miles southeast of Juneau.

Drainage area. 4.30 sq mi.

Records available.--January 1911 to December 1913, August 1916 to December 1920, October 

1946 to September 1956. Monthly discharge only for some periods, published in WSP 

1372. Prior to 1946, published as "near Thane."

Page. Water-stage recorder and wooden control. Datum of gage is 643.5 ft above mean sea 

level (levels by Conservation-Division, U. S. Geological Survey). Prior to August 1916, 

staff gage at same site and datum.

Average discharge. 16 years, 46.5 cfs (33,660 acre-ft per year).

Extremes.--1953-54: Maximum discharge during water year, 499 cfs Oct. 22 (gage height, 

2.62 ft); minimum not determined.

1954-55; Maximum discharge during water year, 462 cfs Aug. 9 (gage height, 2.60 ft); 

minimum, 3.0 cfs Mar. 26-30 (gage height, 0.41 ft).

1955-56: Maximum discharge during water year, 324 cfs May 15 (gage height, 2.09 ft); 

no flow for many days.

1911-13, 1916-20, 1946-56: Maximum discharge, 840 cfs Sept. 8, 1948 (gage height, 

3.60 ft), from rating curve extended above 170 cfs; no flow at times at gage site but 

probably some flow at all times at diversion dam 0.3 mile downstream (records for period 

1916-20 based on measurements at diversion dam).

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

which are poor.

Revisions. WSP 1372: Drainage area.

June 20, 1952, water-stage recorder at several sites three-quarters of a mile upstream 

at various datums. June 20 to Dec. 11, 1952, staff &age at present site and datum.

Extremes. 1953-54: Maximum discharge during water year, 1,050 cfs Dec. 22 (gage height, 

7.25 ft), from rating curve extended above 230 cfs; minimum daily, 0.5 cfs Aug. 28 to 

Sept. 5.

1954-55: Maximum discharge during water year, 1,180 cfs Dec. 20 (gage height, 

8.10 ft), from rating curve extended above 230 cfs; minimum daily, 1.2 cfs July 16-18.

1955-56: Maximum discharge during water year, 1,070 cfs Oct. 23 (gage height,

datum then in use); minimum daily, that of Aug. 28 to Sept. 5, 1954.

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

those above 350 cfs, which are poor. Flow regulated by Lake Connell Dam starting in 

October 1953 (capacity, 11,510 acre-ft). Water diverted above station from Lake Connell

Location.--Lad 62°18'05", long 145°18'20", near center of span on downstream side of 

bridge on Glenn Highway at Gakona, 500 ft upstream from mouth and 1.9 miles northeast 

of junction of Richardson and Glenn Highways.

Drainage area.--620 sq mi, approximately

Records available. Discharge: August to September 1948, October lyiy to September 1956 

Chemical analyses: February 1952 to September 1954. 

Water temperatures: October 1952 to September 1954. 

Sediment records: May 1953 to September 1955, May to August 1956 (periodic).

Gage.--Wire-weight gage read once daily. Datum of gage is 1,403.03 ft above mean sea 

level. Aug. 8 to Sept. 13, 1948, staff gage at same site and datum.

Average discharge.--? years, 901 cfs (652,300 acre-ft per year).

Extremes. 1953-54: Maximum discharge during water year, 8,280 cfs Aug. 3 (gage height, 

7.32 ft, from graph based on gage readings); minimum observed, 22 cfs Nov. 5 (discharge measurement).

1954-55: Maximum discharge observed during water year, 3,060 cfs Aug. 26 (gage 

height, 5.22 ft); minimum daily, 1 cfs Nov. 13, caused by temporary storage behind ice 

Jams upstream.

1955-56: Maximum discharge during water year, 10,300 cfs Aug. 1 (gage height, 

7.92 ft, from graph based on gage readings), from rating curve extended above 5,700 cfs 

by logarithmic plotting; minimum daily, 28 cfs Nov. 3, 4.

1948, 1949-56: Maximum discharge, that of Aug. 1, 1956; no flow for part of 

Mar. 25, 1953, caused by temporary storage behind ice jam upstream.

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. Records of specific conductance of daily samples available in district office, Quality of 

Water Branch, at Palmer, Alaska.

survey). July to November 1913, staff gage half a mile upstream at different datum.

Average discharge.--9 years, 251 cfs (181,700 acre-ft per year).

Extremes. 1953-54: Maximum discharge during water year, 3,090 cfs July 31 (gage height, 

6.07 ft), from rating curve extended above 1,450 cfs by logarithmic plotting; minimum, 

17 cfs about Mar. 28 (gage height, 1.15 ft).

1954-55: Maximum discharge during water year, 3,470 cfs Aug. 27 (gage height, 

6.34 ft), from rating curve extended above 1,450 cfs by logarithmic plotting; minimum, 

22 cfs Apr. 26-30 (gage height, 1.34 ft).

1955-56: Maximum discharge during water year, 2,860 cfs July 31 (gage height, 

5.94 ft), from rating curve extended above 1,450 cfs by logarithmic plotting; minimum 

not determined.

1947-56: Maximum discharge recorded, 5,540 cfs Sept. 25, 1949 (gage height, 7.65 ft), 

from rating curve extended above 1,450 cfs by logarithmic plotting; minimum recorded, 

13 cfs Apr. 29, 1950 (gage height, 1.50 ft), but may have been less during periods of 

no gage-height record.

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

which are poor.

"Commission benchmark). Prior to Nov. 2, 1950, wire-weight gage at bridge 120 ft upstream at same datum. Nov. 2, 1950, to Apr. 30, 1952, wire-weight gage at bridge 100 ft 

upstream at same datum.

Average discharge. 7 years, 4,047 cfs (2,930,000 acre-ft per year).

Extremes. 1953-54: Maximum disctiarge during water year, 21,500 cfs July 31 (gage height, 

8.71 ft); minimum not determined.

1954-55: Maximum discharge during water year, 24,000 cfs Aug. 27 (gage height, 

9.96 ft); minimum daily, 400 cfs Mar. 12.

1955-56: Maximum discharge during water year, 21,400 cfs July 31 (gage height, 

10.50 ft); minimum daily, 234 cfs Apr. 25.

1949-56: Maximum discharge, that of Aug. 27, 1955; maximum gage height observed, 

12.03 ft July 11, 1949; minimum daily discharge, that of Apr. 25, 1956.

Remarks. Records fair except those for periods of ice effect, shifting-control or no 

gage-height record, which are poor. Large diurnal fluctuation caused by glacier melt 

at the source.

Gage. Wire-weight gage read once daily. Datum of gage is 1,682.85 ft above mean sea 

level.

Average discharge. 7 years, 2,135 cfs (1,546,000 acre-ft per year).

Extremes. 1953-54: Maximum discharge during water year, 6,550 cfs Aug. 5 (gage height, 

10.78 ft); minimum not determined.

1954-55: Maximum discharge during water year, 6,500 cfs July 29 (gage height, 

10.49 ft); minimum not determined.

1955-56: Maximum discharge during water year, 7,400 cfs July 14 (gage height, 

11.11 ft); minimum not determined.

1949-56: Maximum discharge observed, 8,860 cfs Aug. 9, 1953 (gage height, 12.10 

ft); minimum discharge not determined.

Remarks.--Records good except those for periods of doubtful gage-height record, which are 

fair, and those for periods of ice effect or no gage-height record, which are poor. 

Large diurnal fluctuation caused by glacier melt at the source.

Drainage area. 1,980 sq mi, approximately (includes that of Noyes Slough)

Records available.--Discharge: July 1947 to September 1948 (no winter records), October 

1948 to September 1956.

Chemical analyses: May to September 1953, April to September 1955.

Water temperatures: May to September 1953.

Sediment records: January to August 1954,. April to September 1955 (periodic).

Gage. Wire-weight gage read twice daily. Datum of gage is 423.68 ft above mean sea 

level. Prior to May 3, 1948, staff gage at same site and datum.

Average discharge. 8 years, 1,500 cfs (1,086,000 acre-ft per year).

Extremes. 1953-54: Maximum discharge during water year, 6,690 cfs July 23 (gage height, 

5.08 ft, from graph based on gage readings); minimum not determined.

1954-55: Maximum discharge during water year, 13,800 cfs June 15 (gage height, 

9.18 ft, from graph based on gage readings); minimum not determined.

1955-56: Maximum discharge during water year, 12,100 cfs Aug. 14; maximum gage 

height, 8.56 ft May 8; minimum discharge not determined.

196 DISCHARGE MEASUREMENTS AT POINTS OTHER THAN GAGING STATIONS

Measurements of streamflow in Alaska made at points other than regular gaging stations 

are given in the following table. Most of these measurements were made during periods of 

base flow when streamflow is primarily from ground-water storage. Measurements believed to 

have been made under base-flow conditions are identified by an asterisk {*) to the left of 

the discharge figure. These measurements when correlated with the simultaneous discharge 

of a nearby stream where continuous records are available will give a picture of the lowflow potentiality of stream. The column headed, "Measured previously" shows the water 

years in which measurements were made at the same, or practically the same, site.
