Utah Lake is a freshwater lake in the
U.S. state of
Utah. It lies in
Utah Valley, surrounded by the
Provo-
Orem metropolitan area. The lake's only river outlet, the
Jordan River, is a tributary of the
Great Salt Lake. Evaporation accounts for 42% of the outflow of the lake, which leaves the lake slightly
saline. The elevation of the lake is legally at above sea level. If the lake elevation goes any higher, the pumps and gates on the Jordan River are left open.
