Kachess Drought Relief Pumping Plant

Kachess DamThe Kachess Drought Relief Pumping Plant (KDRPP) is one of several potential surface-water supply projects being studied by the Bureau of Reclamation and the Washington State Department of Ecology (Ecology) to improve water resources management in the Yakima River basin. KDRPP is being developed under the Yakima River Basin Water Enhancement Project (YRBWEP) as part of the Yakima Basin Integrated Plan.

Previously referred to as the Kachess Reservoir inactive storage project, the proposed KDRPP could withdraw up to 200,000 acre-feet of inactive storage water below the reservoir’s existing outlet works. It would pump and transfer water into the Yakima River for appropriate distribution. The KDRPP would operate only in a Washington State-declared drought with the goal of providing up to 70 percent water rights to proratable users, when feasible. KDRPP was proposed along with the Keechelus Reservoir-to-Kachess Reservoir Conveyance (KKC) Project, which would help refill the Kachess Reservoir in the years following a drought in which KDRPP is used.

Since the proposed KKC and KDRPP projects are closely connected, Reclamation and Ecology prepared the Kachess Drought Relief Pumping Plant (KDRPP) and Keechelus Reservoir-to-Kachess Reservoir Conveyance (KKC) Draft Environmental Impact Statement (DEIS), in a single National Environmental Policy Act (NEPA) and State Environmental Policy Act (SEPA) document. It includes environmental analyses for both the KKC and KRDPP. The DEIS was released in January 2015 and described the no-action alternative and five action alternatives. The public comment period ended June 15, 2015.

After the public comment period, Reclamation and Ecology reviewed the comments on the DEIS, collected additional scientific data as necessary, evaluated new findings, and developed a floating pumping plant alternative. The new alternative and new findings were documented in the Kachess Drought Relief Pumping Plant and Keechelus Reservoir-to-Kachess Reservoir Conveyance Supplemental Draft Environmental Impact Statement (SDEIS), released to the public April 13, 2018.

After a 90-day public comment period on the SDEIS, Reclamation and Ecology prepared the Kachess Drought Relief Pumping Plant and Keechelus Reservoir-to-Kachess Reservoir Conveyance Final Environmental Impact Statement (FEIS) that was released to the public on March 6, 2019. Responses to comments from both the DEIS and the SDEIS are published in the FEIS.

The Record of Decision (ROD) for the FEIS was signed by Pacific Northwest Regional Director Lorri Gray on April 26, 2019. You may access ROD and the FEIS under "Reports" below. If you would like to receive a hard copy of the ROD, please call the request line at (509) 573-8193 or email to kkbt@usbr.gov. You may also request a CD or a 3-volume-set hard copy of the FEIS.
