Irrigation water was one of the larger proposed uses of the reservoir waters. The waters apportioned for irrigation uses were allotted during the growing season (Apri I through October) as summarized in table 7, and a majority of the control- point diversions and thei r approximate locations are shown in figure 6. For each Irrigation-diversion amount, 67 percent of the diverted water was assumed to be returned to the stream system at some point downstream, and 33 percent was assumed to be consumptively used by plants, evapotranspi,red, or lost by seepage into the ground (Colorado Water Conservation Board and U.S. Department of Agricuiture, 1969). Because of the large number involved, most return-flow control points are not shown in figure 6.

The net consumption of water used for municipal purposes was assumed to be one-third, whereas industriai users were assumed to consumptively use all water diverted. The amount of water required for wet-tower cooling systems in coal-fired electric.power generation plants Was adapted from computations from Palmer and others (1977). The approxi- mate water required for wet-tower cool ing is 27,000 acre-feet (33.3 hm3) for each 2,000 megawatts of electricity generated, or a constant flow rate of 37 ft3/s (1.04 m3/s) per 2,000 megawatts.
