• Title: Demonstrating Water Augmentation by Cloud Seeding in the Colorado River Basin
• Date: 5/1/1974
• Weather Modification - Doc Type: Report

The North American estimate is for an average 13.2 percent

increase in streamflow. The preceding graph shows the annual

percentage increa~e potential that existed during the 1952-

f

1971 historic period. This study particularly shows the

value of seeding in-much below normal years such as the 19.5

"

percent flow increase in 1963 or 16.8 percent increase in

1964. Volume increases estimated by water-year are:

1952 2,052,000 a. f. 1962 1,641,000 a. f.
1953 1,060,000 a. f. 1963 982,000 a. f.
1954 940,000 a. f. 1964 1,025,000 a.f.
1955 1,045,000 a. f. 1965 1,695,000 a.f.
1956 1,348,000 a. f. 1966 948,000 a.f.
1957 1,878,000 a.f. 1967 1,173,000 a.f.
1958 1,631,000 a. f. 1968 1,33l,000 a. f.
1959 1,024,000 a. f. 1969 1,33l,000 a.f.
1960 1,240,000 a. f. 1970 1,492,000 a.f.
1961 1,086,000 a.f. 1971 1,384,000 a. f.
Average 1,3l5,000 acre-feet annually

Utility and benefit of augmenting the flow of the Colorado River

and to some extent the downwind increases, are in "three

general catagories:

1. Hydropower generation. - Primarily additional

generation at existing powerp1ants, although the

increment of new water may make additional units more

"
..

feasible at existing dams.
