Cle Elum Lake is a lake and reservoir along the course of the Cle Elum River, in Washington state USA. Cle Elum Lake is the eastern lake of the three large lakes north of Interstate 90 and the Yakima River in the Cascade Range, the other two being Keechelus Lake and Kachess Lake.
Cle Elum Lake is part of the Columbia River basin, as the Cle Elum River is a tributary of the Yakima River, which is tributary to the Columbia River.
The lake is used as a storage reservoir for the Yakima Project, an irrigation project run by the United States Bureau of Reclamation. Although a natural lake, Cle Elum Lake's capacity and discharge is controlled by Cle Elum Dam, a 165 foot (50 m) high earthfill structure built in 1933. As a storage reservoir, Cle Elum Lake's active capacity is 436,900 acre feet (539,000,000 m³).[1]
