THE COLORADO RIVER PROBLEM 339 TABLE 14.—Probable Power Demand of Southern California. Year. Per Fowler: Increase at: 13% to 1925 12% to 1930 10% to 1935 8% to 1940 in millions of kilowatt-hours. (1) Per Markwart: Increase at: 11.1% to 1930 7.2% to 1940 4.1% to 1950 in millions of kilowatt-hours. (2) Fowler's Estimate: Assume hydro produces 80% of kilowatt-hours and operates at 55% capacity factor. Required installed capacity, in kilowatts. (3) Markwart's Estimate: Hydro produces 80% of kilowatt-hours and operates at 72% capacity factor. Required installed capacity, in kilowatts. (4) Possible installed capacity of Southern California hydro per Table 12.

S. Bureau of Reclamation, gives information on reservoir sites on the upper tributaries. Of these sites, it may be stated that: 1.—The Ouray site will be expensive to develop, because of depth to bedrock and width between abutments. 2.—The Kremmling site is probably unavailable on account of interference with the Denver and Salt Lake Railroad. 3.—The Bedrock site commands a relatively small run-off.
