Kachess Drought Relief Pumping Plant
(Kachess Reservoir Inactive Storage Project)

Kachess ReservoirThe Bureau of Reclamation and Washington State Department of Ecology are conducting a feasibility study for the Kachess Drought Relief Pumping Plant (KDRPP) (formerly identified as Kachess Reservoir Inactive Storage Project) to examine the feasibility and acceptability of withdrawing an additional 200,000 acre-feet of water from Lake Kachess and transferring that flow into the Yakima River for beneficial downstream use in a drought year.  
 
The KDRPP is one of several potential surface water supply projects being studied to improve water resources management in the Yakima basin being developed under the Yakima River Basin Water Enhancement Project (YRBWEP) Yakima River Basin Integrated Water Resource Management Plan (Integrated Plan).  The purpose of the Integrated Plan is to provide additional water supply for agriculture and municipal and domestic uses as well as improving ecological conditions for fish.  The Integrated Plan was developed under authority provided to Reclamation by under the 1979 YRBWEP Feasibility Study Authorization (Public Law 96-162, December 28, 1979); existing YRBWEP Act (P.L. 103-434, October 31, 1994, as amended by P.L. 105-62, October 13, 1997; and P.L. 106-372, October 27, 2000).  The Integrated Plan, in effect, constitutes Phase 3 of YRBWEP.

The KDRPP Feasibility Study will be performed concurrently with the Keechelus-to-Kachess Conveyance (KKC) Project Feasibility Study.  Each separate study will produce its own feasibility reports including a planning report, feasibility design report, and economics technical report.  However, due to the potential connectivity of the two projects, a single environmental impact statement (EIS) will be prepared, which will include environmental analyses for both proposed projects.

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