QUALITY OF SURFACE WATERS

FOR IRRIGATION, 

WESTERN UNITED STATES, 1958

INTRODUCTION

The records of chemical analyses, other physical measurements, and discharge given in this report comprise the eighth 

annual compilation of data for 81 irrigation network stations in 

operation west of the Mississippi River.

Geological Survey Water Supply Papers 1264 and 1362, the annual compilations for water years 1951 and 1952, respectively, 

describe briefly the development of this series of reports. In 

summary, there is an expressed need for comprehensive continuing information about the chemical quality of surface waters used 

for irrigation and the changes resulting from the drainage of irrigated lands.

In recognition of this problem the Subcommittee on Hydrology, 

Interagency Committee on Water Resources (formerly the Federal 

Interagency River Basin Committee) onFebruary 6, 1950, approved 

a list of 106 network stations on streams in Western United States 

at which water samples were to be collected and analyzed with 

particular reference to the use of these streams waters for irrigation. These stations, with pertinent information about periods of 

operation, are shown in the following table. Of the 106 stations 

selected, 39 were already being operated by the Geological Survey 

and 7 by the International Boundary and Water Commission. From 

the remaining stations on the list, 30 were selected for activation 

by the U.S. Geological Survey during the fiscal year 1951. In addition, 3 stations previously operated in connection with other programs and scheduled to be discontinued were to be included in the 

list to be operated by the Geological Survey (the Subcommittee 

amended the list on October 2, 1952,to include the three additional 

stations, bringing the recommended number of irrigation network 

stations to a total of 109).

It was contemplated that the network stations would be located 

at streamflow gaging stations and that the program of collecting 

and analyzing the samples and reporting the findings would be the

responsibility of the Geological Survey. The scope of the chemical 

analyses would provide for the calculation of the salt burden of 

stream and in general would conform with the current Geological 

Survey standards for the comprehensive investigation of the chemical quality of surface waters.

The following criteria were recommended in the selection of 

the key network stations.

1. All recommended stations should be located on streams 

west of the main stem of the Mississippi River.

2. All proposed stations should relate primarily to irrigation 

although multiple-purpose needs which include irrigation maybe 

considered.

3. All stations should be located at or near streamflow gaging 

stations. The most nearly up-to-date list of gaging stations currently operated by the U.S. Geological Survey (which comprises 

all but a small percentage of all gaging stations) will be found in 

the most recently published Geological Survey water-supply papers 

for the areas involved.

4. Consideration should be given to the location of irrigation 

development areas that are now affecting or are likely to affect 

the chemical quality of the river water.

5. Only those stations should be proposed that are likely to reflect important changes in chemical quality over a period of years. 

Stations operated for relatively short period (5 years or less), 

as would be required for intensive studies of specific projects, 

should not in general be included.

Plate 1 is a plot of the recommended list of 109 net work stations 

on streams in Western United States. The 81 stations in operation 

in 1958 are identified by a solid circle. The period of record, in 

years, is also shown at each of these stations. In a few instances 

the period of record differs from that obtained from the date established by the Subcommittee, as earlier records were included also. 

Proposed stations are identified by an open circle.

To facilitate identification, each Geological Survey gaging station and sampling station has been assigned a station number. The 

station numbers were assigned according to Geological Survey 

practice in reporting records of streamflow: Stations on tributary 

streams are listed between stations on the main stem in the order 

in which those tributaries enter the main stem. However, in this 

report the numbers will not all appear in increasing numerical 

order because all the main stem stations on a river are reported 

before listing the stations on the tributaries.

The complete number for each station has eight digits, but the 

station number as shown in this report just to the left of the station name consists of only the digits essential for identification. 

For example, for a station with the complete number 04-0100.00, 

this station number shown in this report is 4-100.

During the 1958 water year, two stations were relocated. James 

River at Huron, S. Dak., was relocated to James River upstream 

from diversion, at Huron, S. Dak., and Columbia River at international boundary was relocated to Columbia River at Northport, 

Wash. The Republican River near Hardy, Nebr., was discontinued.

During 1957 58, the United States Section of the International 

Boundary and Water Commission operated the stream gaging stations for the following Rio Grande stations included in this report: 

El Paso, Fort Quitman, Upper Presidio, Langtry, Falcon Dam U.S. 

tailrace and it operated the station Pecos River near Shumla, also. 

The Mexican Section operated the stream gaging station on the 

main stem at Laredo. Each section operated the gaging stations 

on tributary streams, floodways, and diversions within its own 

country.

Descriptive headings and discharge data for the seven stations 

operated by the International Boundary and Water Commission, 

were obtained from Water Bulletins 27 and 28 prepared jointly by 

the United States and Mexican Sections of the International Boundary and Water Commission. These publications contain stream

discharge and related data for 1957 and 1958. Analyses for seven 

Rio Grande main stem stations and for the Pecos River near 

Shumla, Tex., were obtained from the U. S. Salinity Laboratory, 

Riverside, Calif.

Additional contributions of data have been made by individuals, 

corporations and other State and Federal agencies, and their cooperation is acknowledged with appreciation.

COLLECTION OF SAMPLES

In accordance with the recommendation of the Subcommittee, 

where practicable, one sample was collected each day throughout 

the water year. In general, each sample was taken in an 8- or 12- 

ounce glass bottle provided with a pressure-type or positive-seal 

closure to prevent escape of dissolved gases. Each sample was 

integrated in the vertical section of a stream usually at about 

midpoint of flow by lowering the open sample bottle to the bottom 

and returning it to the surface during the filling process.

At most stations the samples were collected by local residents 

hired for the purpose. The local sample collector recorded on 

each bottle the name of the stream, location, gage height (if practicable), water temperature, time of day, date, and collector's 

name or initials. Samples were shipped to the laboratory or 

picked up by technical personnel on a predetermined schedule. 

Visits were made periodically by technical personnel to check on 

sampling procedures.

EXAMINATION OF SAMPLES

Upon receipt of samples in the laboratory, they were recorded 

and stored away from direct sunlight until opened for analysis. 

Specific conductance was determined with a conductance bridge 

on each sample as soon as opened. These data provided a basis 

for compositing a series of daily samples, for complete analysis. 

In general, a minimum of three composites a month consisting of 

equal volumes of approximately 10 daily samples, were prepared 

for chemical analysis. Individual samples that showed differences 

in conductance of more than 30 percent of the mean for the period 

were not included in the composite, but were grouped separately 

for additional composite samples or analysis of the individual 

sample was made. For those stations where acceptable discharge 

values were reported with the samples or could be obtained 

promptly from rating tables, samples were prepared by mixing 

volumes of individual samples in proportion to water discharge.
REPORTING OF DATA '

The following series of 15 determinations (schedule 1) were 

made on all composite samples for all new network stations during the first year of operation: Silica, iron, calcium, magnesium, 

sodium, potassium, bicarbonate, carbonate, sulfate, chloride, fluoride, nitrate, boron, dissolved solids, and specific conductance. 

The following values were calculated from the analytical data: 

Dissolved solids in tons per acre-foot, dissolved solids in total 

tons, total hardness, noncarbonate hardness, and percent sodium.

It was further recommended by the Subcommittee that during 

the second and third years the following series of 11 determinations (schedule 2) would be made on all composite samples: Calcium, magnesium, sodium, bicarbonate, carbonate, sulfate, chloride, nitrate, boron, dissolved solids, and specific conductance. 

Hardness, noncarbonate hardness, percent sodium, total tons and 

tons per acre-foot would be calculated as in schedule 1.

In the fourth and succeeding years (unless significant changes 

become apparent) it was recommended that the following determinations (schedule 3) would be made on all composite samples 

as long as the program is in effect: Calcium and magnesium 

(either separately, or together by the recently developed ethylenediamine tetraacetic acid titration test for hardness), sodium, dissolved solids, and specific conductance. In addition, four complete 

analyses (schedule 1) would be made each year, one analysis to be 

made on a composite sample during each quarter. Certain additional determinations above these minimum requirements were to 

be made if deemed necessary to define widely varying characteristics of the stream water.

All laboratory determinations were to be made in accordance 

with standard procedures used by the Geological Survey. These 

procedures are based on methods found in authoritative publications on water analysis.

REPORTING OF DATA

In order to release the data in the form most widely used in the 

evaluation of irrigation waters, the results of analyses in this 

compilation are given in equivalents per million, rather than the 

conventional unit part per million. Some agencies that actively 

participate in irrigation water-quality investigations prefer to 

express results in milligrams per liter (mg/1) and milliequivalents per liter (meq/1). However, for all practical purposes where 

concentrations of dissolved solids are less than about 7,000 parts 

per million, no correction for density of the water is necessary 

and the units reported in each method are considered to be synonymous.
8 QUALITY FOR IRRIGATION, 1958

If results are desired in parts per million they can be calculated 

by multiplying the reported values in equivalents per million by 

the chemical combining weights of the individual constituents. 

Pertinent physical data and water discharge are also included in 

the tables.

EXPLANATION OF TABLES

The tables of analyses beginning on page 22 include a brief 

descriptive heading summarizing the more pertinent features at 

each station as follows:

Location of Station is given generally as the distance in land or river 

miles from a town or other political or geographic feature. In 

Survey practice the term "at" generally implies that the station 

is within a mile radius of the named town whereas "near" implies 

that it is beyond a mile radius.

Drainage area above the gaging station was obtained from the most 

recent published records of the annual reports of the Geological 

Survey on Surface Water of the United States, and from the International Boundary and Water Commission.

Records available are given for all periods during which samples, 

other than infrequent, were collected for chemical analyses. It 

does not include the periods for which discharge records are 

available.

Extremes for the current year and for the period of record are 

reported for specific conductance and percent sodium because of 

their widespread application in the evaluation of analyses of water 

used for irrigation. The results for specific conductance are 

based on the measurement made at the laboratory upon receipt of 

the sample from the field. Data for percent sodium were obtained 

from the composite-samples analysis.

Remarks include sources of data, additional explanation concerning the records, and offices where the records of chemical quality 

may be obtained.

Discharge of records were obtained from the responsible Geological 

Survey Surface Water Branch offices except for the seven stations 

operated by the International Boundary and Water Commission. 

Discharge data are shown in acre-feet, calculated from the mean
DISCUSSION OF RESULTS y

daily discharge in cubic feet per second by multiplying by the 

factor 1.983.

Analytical values are reported in equivalents per million for cations 

and anions. The equivalent is the weight with reference to some 

standard (such as the combining weight either of oxygen, 8, or 

of hydrogen, 1.008) of that quantity of an element, radical, or compound to complete a definite chemical reaction. An equivalent of 

an element or ion is exactly equal in combining power to one 

equivalent of another element or ion. As previously discussed, 

for concentrations of dissolved solids that are normally encountered in water for irrigation, an equivalent per million is equal 

to a milliequivalent per liter. Silica, which is considered to be 

present in the colloidal state, and boron, are reported in parts 

per million. Percent sodium is calculated as follows:

NaxlOO

, where all constituents are reported in equivalents Na +K +Ca +Mg 

per million.

At the recommendation of the Subcommittee, sodium-adsorptionratio (SAR) is published for all network stations beginning October 1952. The term is defined and described under "Sodium 

hazard" on page 20.

DISCUSSION OF RESULTS

Discharge data and dissolved-solids loads for stations operated 

in 1958 are summarized in the following table.

HUDSON BAY AND UPPER MISSISSIPPI RIVER BASINS

Red River of the North tiasin. Precipitation in the Red River of the 

North basin In North Dakota was less than the long-term mean. 

Runoff was in the median range during the fall,above normal during the winter because of unusually mild temperatures, and greatly 

deficient during late spring and summer in much of the basin. 

Runoff for Sheyenne River at Warwick was 17,100 acre-feet compared with a 9-year average of 45,460 acre-feet, and runoff for 

Souris River near Westhope was 27,810 acre-feet compared with 

a 23-year average of 158,400 acre-feet. Although the runoff was 

about 7 percent less at Warwick and about 50 percent less at Westhope than in 1957, the dissolved-solids content increased by about 

20 percent at both stations. The dissolved-solids content at Warwick was the highest since 1953.

MISSOURI RIVER BASIN

Missouri River main stem. The Missouri River is regulated by the 

following dams: Canyon Ferry and Fort Peck, upstream from 

Williston, N. Dak.; Garrison and Oahe, between Williston, N. Dak., 

and Pierre, S. Dak.; and Fort Randall and Gavins Point, between 

Pierre, S. Dak., and Nebraska City, Nebr. Closure of the Oahe 

Dam was made in August 1958. The Missouri River will be virtually one large reservoir extending from Williston, N. Dak., to 

Yankton, S. Dak., after completion of Big Bend, a dam that will be 

built between the Oahe and Fort Randall Dams in South Dakota.
12 QUALITY FOR IRRIGATION, 1958

The total amount of water in storage in the main-stem reservoirs 

on Sept. 30, 1958, was slightly more than 23,000,000 acre-feet, the 

most that has ever been in storage and which is an increase of 

about 1,500,000 acre-feet since Sept. 30, 1957. Eventually, some 

of the water stored in the reservoirs is to be used for irrigation; 

but currently, the water from Canyon Ferry Reservoir is used 

partly for irrigation, and the water from the other reservoirs is 

used for electric power generation, flood control, pollution control, municipal supply, navigation, and recreation.

In general, precipitation was more than long-term mean in the 

basin downstream from Yankton, S. Dak.; but it was less than 

long-term mean in the basin upstream from Yankton, and drought 

conditions prevailed in parts of eastern Montana and western 

North Dakota. Because of the tremendous amount of storage and 

control upstream from Yankton, local variations in climatic conditions only slightly affect the chemical quality of the water.

The average chemical quality, weighted with discharge, for the 

1958 water year was about the same as that for previous years. 

For example, the average dissolved-solids content at Williston 

was 439 ppm for 1958 compared with 416 ppm for the 8-year 

period 1951-58; at Pierre, 44 ppm compared with 440 ppm; at 

Nebraska City, 425 ppm compared with 431 ppm.

Fluctuations in water quality were apparent at all three sites 

on the main stem, but those at Nebraska City were relatively 

small; those at Williston are due to variations in flow from Fort 

Peck Reservoir and from the Yellowstone River, and those at 

Pierre are due to variations in inflow from the tributaries between Garrison Reservoir and Pierre. Closure of Oahe Dam will 

probably cause the flow at Pierre to be fairly uniform in quality.

Yellowstone River Basin. Runoff for the whole basin was less than in 

1956 and 1957, and also less than the long-term average. Likewise runoff from the basin above Billings, Mont., was less than in 

1956 and 1957, and also less than the long-term average.

The dissolved-solids load at Sidney, Mont., was less than the 

loads in 1956 and 1957, but higher than the 1955 load. The discharge during the 1956 and 1957 years was comparatively high. 

The decrease in load in 1958 was caused primarily by a decrease 

in load carried by the Yellowstone River and its tributaries above 

Billings, and by a decrease in load carried by the Bighorn River 

at Bighorn, Mont. Weighted-averages of the chemical constituents 

were greater during 1958 than in 1957 at all stations and also 

greater than those recorded in 1956, with the single exception of 

the Bighorn River at Bighorn. Twenty-six percent of the dissolvedsolids load at Sidney was contributed by the Yellowstone River
DISCUSSION OF RESULTS 13

above Billings, 54 percent by the Bighorn River, 3 percent by the 

Tongue River, and 9 percent by the Powder River. Eight percent 

of the dissolved-solids load at Sidney is assumed to have been 

contributed by minor tributaries and the Yellowstone Valley between Billings and Sidney.

The major reservoirs in operation in the Yellowstone River 

basin are Buffalo Bill Reservoir on the Shoshone River and Bull 

Lake, Pilot Butte, and Boysen Reservoirs on the Wind River.

There were no significant changes in impoundment or diversion, 

and no variations in methodology from that proposed for irrigation network stations.

James River basin. The James River has alow gradient and becomes 

a series of pools during periods of low flow. Many small dams and 

diversions along the river impound water for public supply.

Runoff for James River at Huron, S. Dak., was only 77,140 acrefeet compared with a 16-year average of 166,500 acre-feet. The 

dissolved-solids content increases significantly during the winter.

Platte River basin. Since the completion of Glendo Reservoir near 

Glendo, Wyo., in October, six reservoirs are in operation on the 

main stem of the North Platte River. Glendo Reservoir was filled 

for the first time with the water released from Pathfinder Reservoir near Alcova, Wyo., which was emptied to allow work to proceed on a new penstock and powerplant. For North Platte River 

below Guernsey Reservoir, Wyo., runoff was the highest since 

1953, and the annual average dissolved-solids content was the 

lowest for the 7 years of record.

Streamflow was exceptionally high in the South% Platte River in 

Colorado, mainly because of full reservoirs and low irrigation demands. The runoff for South Platte River at Julesburg increased 

75 percent over that of 1957. It was the highest runoff of any year 

for which water-quality records have been obtained. The weighted 

averages increased by about one-tenth over those of 1957 but were 

considerably lower than those of other years of record.

For Platte River at Brady, Nebr., and Supply Canal near Maxwell, Nebr., which are below the confluence of the North and South 

Platte Rivers, runoff was the highest since 1952, and dissolvedsolids content was the highest on record. The high dissolved-solids 

content was due to the fact that during 1958 the amount of inflow 

from the South Platte River was proportionately greater than that 

from the North Platte River, and water from the South Platte River 

is generally much more mineralized than water from the North 

Platte River.
14 QUALITY OFR IRRIGATION, 1958

Kansas River basin. Precipitation in the Kansas River basin, especially during late winter and summer, was substantially above the 

long-term mean. However, control by irrigation dams minimized 

flooding.

Controls, upstream from the station Republican River above 

Medicine Creek at Cambridge, Nebr., include Trenton Dam (Swanson Lake), Nebr., on the Republican River, Bonny Reservoir, Colo., 

on the South Fork Republican River, and Enders Reservoir,Nebr., 

on Frenchman Creek. Runoff for this station was only 0.8 percent 

higher than in 1957, but it was the highest since 1951; reservoirs 

were full from the previous year and irrigation demands were low. 

The dissolved-solids content increased by about 10 percent over 

that of 1957 but was almost identical to the 8-year average of 322 

ppm.

Water-quality observations for Republican River near Hardy, 

Nebr., were discontinued Sept. 30, 1957.

LOWER MISSISSIPPI RIVER BASIN

Arkansas River basin. Discharge at the Arkansas City, Kans., station 

was slightly greater in 1958 than in 1957. However, discharges at 

stations in Oklahoma were considerably less for the 1958 water 

year. Annual discharges were about one-half the 1957 values at 

the Whitefield station on the Canadian River and the Tulsa station 

on the Arkansas River. The greatest percent decrease in discharge occurred at the Perkins station on the Cimarron River, 

where runoff was 2,498,000 acre-feet in 1957 but only 687,600 

acre-feet in 1958.

The decrease in runoff in the Arkansas River basin in Oklahoma 

increased the weighted average of dissolved-solids content at the 

sampling stations. The greatest increase occurred in the Cimarron River at Perkins, Okla., where the dissolved solids increased 

from 1,430 ppm in 1957 to 3,550 ppm in 1958. At Ralston, Okla., 

the flow* was about two million acre-feet less than in 1957 and 

dissolved solids increased from 573 ppm to 741 ppm. Although 

the highly mineralized water from the Salt Fork of the Arkansas 

River normally accounts for a considerable part of this increase, 

the major reason was the high flow and abnormally high dissolvedsolids content at the Arkansas City station.

The most unusual change in dissolved-solids content occurred 

at the Arkansas City station in Kansas, where this content increased from 483 ppm in 1957 to 707 ppm in 1958 but the amount
DISCUSSION OF RESULTS 15

of runoff remained about the same. The increase in dissolvedsolids content during 1958 was due to the different runoff characteristics above the station. During 1957, intense rains produced a 

peak discharge of 73,100 cfs as compared to a peak discharge of 

22,100 cfs during 1958. Sixty percent of the runoff in 1957 occurred during the two high-flow months but only 38 percent of the 

annual runoff occurred during the two high-flow months of 1958. 

This greater percentage of dilute runoff during 1957 resulted in 

the lower dissolved-solids content for that year although the annual flow, for both years were about the same.

The percent sodium and the sodium-adsorption ratios in the 

Arkansas River at Arkansas City, Kans., and in the Canadian River 

at Whitefield, Okla., changed little from 1957 to 1958. At the 

Perkins station on the Cimarron River, the percent sodium increased from 75 in 1957 to 83 in 1958. At the Ralston station on 

the Arkansas River the percent sodium dropped from 63 in 1957 

to 58 in 1958 because of a considerable decrease of saline water 

contributed to the Arkansas River by the Salt Fork Arkansas 

River.

Runoff at Arkansas River at Van Buren, Ark., during the 1958 

water year was 25.6 million acre-feet, compared to 39.9 million 

acre-feet in 1957, 4.3 million acre-feet in 1956, and 9.3 million 

acre-feet in 1955. The concentrations of all the major constituents show a slight increase over those of the previous year. Dissolved solids increased from 356 ppm to 447 ppm and the percent 

sodium increased from 52 to 54. The sodium-adsorption ratio 

increased from 2.5 to 2.9.

Red River basin. Discharge for the Red River at Denison Dam, 

near Denison, Tex., during the 1958 water year was 81 percent of 

the long-time average, but was less than half the discharge for 

1957. Average dissolved-solids content was the same both years.

WESTERN GULF OF MEXICO BASINS

In the Western Gulf of Mexico basins from the Sabine River to 

the Nueces River, the runoff for 1958 was above average for the 

second successive water year, and the average dissolved-solids 

content remained about the same for all stations as reported in 

1957.

Rio Grande basin* A trend toward higher annual runoffs improved 

the chemical quality of surface water in New Mexico. This is 

particularly true in the Pecos River basin where the weighted 

average of dissolved solids was lower in 1 958 than in the several 

preceding years. Pecos River below Alamogordo Dam, N. Mex.,
16 QUALITY FOR IRRIGATION. 1958

and Pecos River near Artesia, N. Mex., are sensitive indicators 

of this change. The same trend was noted for the main channel 

stations of the Rio Grande; however, it is not so apparent because 

different origins of runoff as well as artificial controls have 

acted to partially obscure this trend.

Runoff at the station, Pecos River below Red Bluff Dam, near 

Orla, Tex., was only 28 percent of the 21-year average but was 

20 percent greater than in 1957. Weighted average dissolved - 

solids content decreased from 10.9 tons per acre-foot in 1957 to 

8.02 tons per acre-foot in 1958. Storage in Red Bluff Reservoir 

increased during the water year from 14,000 acre-feet to 72,000 

acre-feet.

COLORADO RIVER BASIN

Colorado River main stem. There was an increase in the dissolvedsolids content for the stations at Glenwood Springs, Colo., and 

Cisco, Utah. This change may be attributed to a slight decrease 

is runoff as compared to the preceding year. There was no significant change in chemical character of the water at either 

station.

The quality of the water at the station below Hoover Dam, ArizNev., was relatively constant due to the mixing effect of Lake 

Mead. However, there was a 14 percent decrease in dissolvedsolids content for this station. This was probably the result of 

increased storage in Lake Mead during the preceding year.

Diversions and return flows at and below Imperial Dam. There has been a 

trend toward better quality of water in the Colorado River basin. 

This can be seen best by comparing the weighted-average value 

for dissolved solids at Yuma Main Canal at Yuma, Ariz., with 

figures for past years.

Green River basin. Discharge for the Green River at Green River, 

Utah decreased by 21 percent as compared with last year's flow. 

Total loads for this station decreased only 6 percent since the 

decrease in discharge was accompanied by a 16 percent increase 

in dissolved-solids content. Percent sodium remained relatively 

unchanged at this station.

San Juan River basin. There was no significant change in discharge 

or dissolved-solids content at San Juan River near Bluff, Utah. The 

weighted-average analysis shows that the quality of the water 

continued to be high in calcium and sulfate content. During periods of low flow there is a considerable increase in sodium content.
DISCUSSION OF RESULTS 1 7

Virgin River basin. Percentage composition of the water remained 

unchanged for the Virgin River at Littlefield, Ariz. Although the 

dissolved-solids content decreased 40 percent, the total load past 

the Littlefield station increased 77 percent. The increase in total 

load was the result principally of nearly a threefold increase in 

runoff at this station.

Gila River basin. Runoff in the Gila River basin was considerably 

higher than the previous year. A better quality of water might 

have been expected, but such a prospect was only partially realized due largely to the rigorous control of runoff. Furthermore, 

the quality at certain stations such as the Gila River at Kelvin, 

Ariz., is affected by complex ground-water factors as well as to 

river management of upstream storage.

THE GREAT BASIN

Sevier Lake basin. Flow past the Sevier River station near 

Lynndyl, Utah increased 90 percent and was accompanied by a 

corresponding increase in total loads of 88 percent. The dissolved-solids content and percentage composition of the water at 

this station remained unchanged, probably as the result of storage 

at Sevier Bridge Reservoir.

Humbolt River basin. The percentage composition of the weightedaverage analysis for the Humboldt River near Rye Patch, Nev., 

remained unchanged. A 5 percent decrease in dissolved-solids 

content was accompanied by an increase in discharge of 10 percent and an increase in total loads of 6 percent.

PACIFIC SLOPE BASINS IN CALIFORNIA

San Joaquin River basin. Flow in the basin was considerably greater 

than that of the preceding year and approximately 175 percent of 

a long-term average for the basin. The chemical quality of the 

outflow showed a marked improvement in the 1957 water year. 

The weighted-dissolved-solids load for the San Joaquin River 

near Vernalis, Calif., decreased from 0.42 to 0.21 ton per acrefoot. Average specific conductance at this station was 52 percent 

less than that of the previous year.

Because of impoundment of water behind Friant Dam and extensive irrigation in the San Joaquin Valley, the San Joaquin River 

channel at times carries mainly irrigation return water of poor 

chemical quality.
QUALITY SOR IRRIGATION, 1958

Sacramento River basin. Flow in the basin was about 100 percent 

greater than that of the 1957 water year, although the American 

River at Fair Oaks, Calif., showed little change in runoff because 

of the operation of Folsom Reservoir just upstream from the 

station. There was little change in 6hemical quality of the American River at Fair Oaks from that of the preceding year.

Release of water from Shasta Reservoir for salinity control in 

the delta area and large quantities of dilute waters from the 

Feather and American Rivers help to maintain better chemical 

quality in the Sacramento River than that which prevails in the 

San Joaquin River.

PACIFIC SLOPE BASINS IN WASHINGTON AND UPPER COLUMBIA RIVER BASIN

Columbia River main stem. The dissolved-solids content in tons per 

acre-foot, for Columbia River at Northport, Wash., was the same 

as that reported for the last five years for the station at international boundary. At Grand Coulee Dam, further downstream, 

the tons per acre-foot remained the same as the previous two 

years.

Yakima River basin. The tons per acre-foot value continued to increase as it has in the previous years. Streamflow decreased 40 

percent over the previous year, which in turn was 40 percent less 

than that for 1956.

SNAKE RIVER BASIN

Snake River main stem. There were no significant changes in chemical data reported during the 1958 water year for the Snake River 

near Heise, Idaho. Values for total-salt load and tons per acrefoot of the Snake River at King Hill, Idaho were similar to previous years with little or no variation in percent sodium and 

sodium-adsorption ratio. Downstream at Central Ferry, percent 

sodium, sodium-adsorption-ratio, and tons per acre-foot were 

identical to last year.

Boise River basin. Decreases in total-salt content and tons per 

acre-foot accompanied the decrease in discharge, however percent sodium and sodium-adsorption-ratio remained the same as 

last year.

PACIFIC SLOPE BASINS IN OREGON AND LOWER COLUMBIA RIVER BASIN

Columbia River main stem. Total-salt content decreased 10 percent as 

compared to the previous year, however the tons per acre-foot 

remained the same.
CRITERIA OF WATER QUALITY 19

Wi 11amette River basin. A slight increase in total-salt content was 

observed at the Salem station but due to an increase in discharge, 

the tons per acre-foot values remained the same as last year.

Rouge River basin. Increase in discharge and tons per acre-foot 

raised the total-salt load 30 percent over the 1957 value.

CRITERIA OF WATER QUALITY

Many different classifications of water for irrigation appear in 

the literature; however, most of the development in this field has 

been made in the last 30 years. Scofield and Headley (1921) were 

among the first important contributors to water-quality criteria; 

they pointed out the hazards from the use of high-sodium water. 

A brief historical resume of these early developments is given in 

Water-Supply Paper 1264, the first of this series of reports.

Although the above classifications have relied principally on 

specific conductance as the criterion for total salt concentrations, 

investigators generally place emphasis on the composition of the 

water, as indicated by the analysis of dissolved constituents in 

equivalents per million. For example, Eaton (1950) discusses 

precipitation of calcium and magnesium carbonate and its effects 

on the sodium percentage in the soil solution. Baton's suggestion 

of "residual sodium carbonate" in irrigation waters as related to 

the base exchange of the soil has assumed added importance in 

soil permeability studies.

Thorne and Thorne (1951) in developing a system for classifying 

Utah waters for irrigation used a diagram similar to that of 

Wilcox (1948) and designated categories by a series of numbers 

and letters: 1A.......5E. The numbers 1 to 5 denote increasing

concentrations of dissolved solids, and the letters A to E increasing sodium percentages in the water with increasing probabilities 

for developing alkali soil conditions. Class lA water, in which 

specific conductance ranges from0 to 750micromhos and the percent sodium from 0 to an approximate maximum of 70, can be 

used safely on most soils. Class 5E waters,thos.e having specific 

conductance greater than 5,000 micromhos and percent sodium of 

about 90 and above, are generally unsatisfactory for irrigation.

The United States Salinity Laboratory Staff (1954) recently released a classification that incorporates many of the desirable 

features of the early classifications together with more recent 

developments. Empirical equations are used in developing a diagram for the classification of irrigation waters. Although the 

classification embodies both research and field observations, it 

is tentative and should be used for general guidance only.
20 QUALITY FOR IRRIGATION, 1958

A. Salinity hazard

Waters are divided into four classes: low salinity, medium 

salinity, high salinity, and very high salinity, the dividing points 

between classes being 250, 750, and 2,250 micromhos per centimeter. They range from water that can be used for irrigation of 

most crops on most soils to that which is not suitable for irrigation under ordinary conditions.

B. Sodium hazard

The Salinity Laboratory introduced the term " sodiumadsorption-ratio (SAR),"a ratio for irrigation waters and soil extracts used to express the relative activity of sodium ions in exchange reactions with the soil. This ratio is expressed by the 

equation:

Na+ SAR =

where the concentrations of the ions are expressed in milliequivalents per liter (or equivalents per million for most irrigation 

waters). It has more significance than percent sodium for use as 

an index of the sodium or alkali hazard of the water because it 

relates more directly to the adsorption of sodium by the soil.

Waters are divided into four classes with respect to sodium or 

alkali hazard: low, medium, high, and very high, depending upon 

the SAR value and the specific conductance. At a conductance of 

100 micromhos per centimeter the dividing points are at SAR 

values of 10, 18, and 26, but at 5,000 micromhos the corresponding dividing points are at SAR values of approximately 2.5, 6.5, 

and 11. Waters range in respect to sodium hazard from those 

which can be used for irrigation on almost all soils to those which 

are generally unsatisfactory for irrigation.

C. Boron hazard

In assessing water quality on the basis of boron only, the 

classification uses the limits proposed by Scofield (1936). This 

grouping involves the ranges for sensitive, semitolerant, and tolerant crops, with respect to boron, for each of five classes.

D. Bicarbonate ion hazard

The effect of bicarbonate ion concentration on water quality is expressed in terms of "residual sodium carbonate" (RSC) 

which is defined by the equation:

RSC = (HC03 - + C03 ") - (Ca ++ + Mg*4)
SELECTED REFERENCES 2]

Then in appraising quality of irrigation water with the above 

classifications, the Salinity Laboratory Staff recommends that 

first consideration be given to salinity and alkali hazards, then to 

independent characteristics, boron or toxic elements, any one of 

which may change the quality rating. Factors such as drainage 

and management practics, largely determine the effectiveness of 

irrigation activity.
