SUMMARY

This repott presents estimates of the con-
sumptive u~es and losses from the Colorado
River system for each year from 1971 to
1975. It indludes a breakdown of the benefi-
cial consumptive use by major types of use (ex-
cept mainstr~am reservoir evaporation), by
major tributary streams, and, where possible,
by individuaFStates.
The main stem of the Colorado River rises
in the Rocky Mountains of Colorado, flows
southwesterfYiabout 1,400 miles and termi-
nates in the Gulf of California. Its drainage area
of 242 ,000 s~uare miles in this country rep-

resents one-fifteenth of the area of the United
States. Water is used for irrigation, munici-
pal and industrial purposes, electric power
generation, mineral activities, livestock, fish
and wildlife, and recreation. Large amounts
are exported from the system to adjoining
areas. The following table summarizes annual
water use from the system by basins and
States, including water use supplied by
ground water overdraft. Distribution of water
use by types of use from the various reporting
areas is contained within the body of the re-
port.
