The consumptive use is baSed on a national <br />average of 1 acre-foot per Ye:Jr for each household of four persons (includes all municipal <br />use). Assuming half of this returned to the river basin, the consumptive use per person per <br />year. is approximately 0.12.5 acre.feet. <br /> <br />C. ~arge iroundwatu - Groundwater recha:rge is a, very integrated system and would <br />Il:Qulre additional stUdies and mooeli ng to q\W\tify.

Reservoir evaporation - The average annual evaporation from the basin a5 estimaled by <br />Meyers (1962) is tabulated in Table 4. A!l shown on the table, the entire basin has an annual <br />evaporation of 11172,~OO acre-ft (average is for the full surface area or full capacity of the <br />reservoir). Annual evaporation for principal reservoirs in Wyoming for 1991. due to low <br />reservoirs, was 110,000 3crc.ft (Bureau ot Reclamation's estimate) compared to the average <br />listed in the table of 119,170 acre-it for full capacity.
