Quality of Water - Colorado River Basin (USDI)

Biennial Progress Reports on the "Quality of Water - Colorado River

Basin" are prepared by the Department of the Interior. The initial

report was issued in 1963 and the latest report is dated 1971. The

report displays the past, present modified. and estimated future

quality of the Colorado River at 17 gaging stations for the period
of 1941-1968. The future quality condition as used in this report

is an estimate of the situation after the presently authorized

developments. projects proposed for authorization, and private

developments are placed in operation. The report estimates the

present modified average concentration below Iloover Dam to be

760 mg/l and with future known developments. 1,010 mg/l. At

Imperial Dam the comparable projections are 865 and 1.250 mg/l,

respectively, under the same conditions. No time period is speci-

fied in the report to identify when the projected concentrations

would be reached.

Computer Simulation of the Hydrologic-Salinity Flow

System Within the Upper Colorado River Basin (USU)

Salinity conditions were investigated by Utah State University.

In 1970. they issued a report entitled "Computer Simulation of

the Ilydrologic-Salinity Flow System Within the Upper Colorado

River Basin." This study employed an electronic analog computer
