Along with the Cle Elum Pool Raise, K to K Pipeline, and improvements to Kittitas Reclamation District and Wapatox water delivery systems, power subordination (diverting water from power generation to increase streamflows for fish) at the Roza Dam and Chandler powerplants is one of five structural and operational changes proposed in the Integrated Plan.

A substantial level of subordination has been undertaken for several decades. However, additional subordination at key time periods would support out-migration of steelhead, Chinook, sockeye, and coho juveniles.

Under the Integrated Plan, Roza Powerplant would not be used to produce power in April and May, and the Chandler Powerplant would not be used to produce power in April, May, and June, when streamflows are most critical for outgoing salmon and steelhead.
The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
