Cle Elum Pool Raise

Cle ElumThe Cle Elum Pool Raise Project (Pool Raise) was authorized for implementation, including construction, under the Yakima River Basin Water Enhancement Project (YRBWEP) Title XII, October 31, 1994.  It has also been identified as a component of the Yakima River Basin Integrated Water Resource Management Plan (Integrated Plan).  Section 1206 of Title XII includes authorization to modify the radial gates at Cle Elum Dam to provide an additional 14,600 acre-feet of storage capacity in Lake Cle Elum; provide for shoreline protection of Lake Cle Elum; and provide environmental mitigation for impacts from the Project, as necessary.

The Pool Raise consists of raising the maximum water level of Cle Elum Lake by 3 feet from a current maximum elevation of 2,240 feet to 2,243 feet.  The Pool Raise would increase the volume of available storage in Cle Elum Lake by approximately 14,600 acre-feet, which would be used to improve instream flows for fish.  

Scoping Meetings were held November 20 in Yakima, WA, and November 21 in Cle Elum, WA.
