| Relation | Central Utah Project; Western Waters Digital Library; HISTORIC conditions historically utah lake has been operated as a reservoir since 1872 when a low dam was placed across the outlet to the jordan river A pumping plant was installed in 1902 to lower the lake water level below the outlet elevation the pumping plant has since been modified and enlarged several times its present capacity is about 1050 cfs cs years of high inflow caused utah lake with a dam at its outlet to occasionally rise above its normal elevation and flood the adjacent lands this resulted in disagreements between the land owners and water users until 1885 when a compromise level of the lake was agreed upon the arbitrary elevation agreed on was 4489.34 448934 feet above mean sea level whenever runoff forecasts during the filling season indicate that the lake level will exceed that elevation under controlled operation the outlet gates are opened to permit discharges comparable to natural outflow conditions the gates remain open until the threat of exceeding compromise level has passed or until the lake has subsided to compromise level even under this type of operation the lake level rose to slightly more than 3 feet above compromise level in the extremely highrunoff high hegh runoff years of 1922 and 1952 the pumping plant at the outlet of the lake is capable of lowering the lake level to about 9.3 93 93 feet below compromise level the lake was drawn down to 12 feet below the compromise level by emergency pumps installed on the lakes west shore in 1934 at compromise level the maximum depth of the lake is about 14 feet the surface area is about 95000 acres or 150 square miles and the storage capacity is approximately 900000 acre feet past records show that during the period of study utah lake surface elevations have been near or above compromise level about 13 of the 44 years studied or a rate of about 30 percent the lake has reached high surface levels of over 3 feet above compromise during at least 1 year and has been near or at low surface levels of about 12 feet below compromise during at least 2 years or less than 5 percent of the years studied however low levels have been near or under 9 feet below compromise during about 7 years or 16 percent of the years studied the 122 1 22 |
