Relation Central Utah Project; Western Waters Digital Library; longterm long term average has been about 44 feet below compromise elevation under historic conditions the lake surface area has averaged about 82000 acres total annual inflow to the lake has averaged about 579000 acre feet evaporation and transpiration from utah lake and its shoreline vegetation has been high averaging about 4 feet in depth from the lake or a total of about 330000 acre feet annually this represents more than half of the average annual inflow into the lake FUTURE conditions WITHOUT THE PROJECT under future conditions without the bonneville unit diking plan the operation of utah lake would change from historic conditions as a result of expected changes in inflow and outflow from the lake because of full operation of the provo river project existing major features include the duchesne tunnel deer creek reservoir salt lake aqueduct and provo reservoir canal under these conditions the lake could still be drawn down to 120 12.0 120 feet below the compromise level as was done historically during the drought years of 1934 and 1935 it is also possible due to economic water quality and other constraints that the maximum drawdown would not exceed the 93 9.3 93 foot level A comparison of these two potential future conditions without the project follows 9.3 93 93 ft drawdown 120 12.0 120 ft drawdown average lake elevation 38 3.8 38 ft 41 4.1 41 ft average surface area 84000 acres 83000 acres average annual inflow 577000 ac ft 577000 ac ft average annual outflow 240000 ac ft 244000 ac ft average annual evaporation 335000 ac ft 328000 ac ft 1 23
