Keechelus-to-Kachess Conveyance Project

Kachess ReservoirThe Bureau of Reclamation and Washington State Department of Ecology are conducting a feasibility study for the Keechelus-to-Kachess Conveyance (KKC) Project to examine the feasibility and acceptability of conveying water from the Keechelus Reservoir to Kachess Reservoir in order to reduce flows in the upper Yakima River for fish rearing and habitat, and to augment flows into Kachess Reservoir to improve the capability for refill in dry years.

The KKC Project is one of several potential structural and operation changes projects being analyzed to improve water resources management in the Yakima River basin. The Study is being performed 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 KKC Feasibility Study is being performed concurrently with the Kachess Drought Relief Pumping Plant (KDRPP) (formerly identified as Kachess Reservoir Inactive Storage) Feasibility Study. The KDRPP Feasibility Study involves analyses of accessing reservoir water currently stored below the elevation of the existing reservoir outlet works. Each separate study will produce its own feasibility reports including a planning report, feasibility design report, and economics technical report. Due to the potential connectivity of the two projects, a single environmental impact statement (EIS) has been prepared and includes site-specific environmental analysis for both proposed projects. In addition to a No Action Alternative, five action alternatives are evaluated in the Draft EIS.

In January 2015, a Draft Environmental Impact Statement (EIS) for the Kachess Drought Relief Pumping Plant (KDRPP) and Keechelus Reservoir-to-Kachess Reservoir Conveyance (KKC) Projects was released and the public comment period ended March 10. After considering the comments contained in hundreds of letters from the public, Reclamation and Ecology are reopening the comment period for an additional 60 days. The new comment period will end June 15, 2015.

During that time, four additional public meetings will be held:

May 4, 2015
Hal Holmes Center in Ellensburg, WA
1:30-3:30 p.m. and 5-7 p.m.
May 5, 2015
U.S. Forest Service Ranger District office in Cle Elum, WA
1:30-3:30 p.m. and 5-7 p.m.
