Melvin R. Sampson Hatchery, Yakima Basin Coho Project (DOE/EIS-0522)
Kittitas County, Washington

BPA is proposing to fund the Confederated Tribes of the Yakama Nation to construct a coho hatchery in Kittitas County, Washington. 

The hatchery would initially rear and release 500,000 parr and 200,000 smolts in the upper Yakima and Naches River watersheds using broodstock collected from existing facilities at Roza and Prosser Dams, or at other existing collection sites.  Coho releases would occur in Yakima and Naches River tributaries, with a portion of coho smolts being released using mobile acclimation units. The hatchery would help restore natural spawning of coho in the in the Yakima River basin and provide harvest opportunities.  The project would help mitigate for effects of the Federal Columbia River Power System on fish and wildlife in the mainstem Columbia River and its tributaries. 

The hatchery would be on an 8-acre portion of the Holmes Ranch property about 5 miles northwest of Ellensburg.  The hatchery would include intake screens and a pump station to provide water from an existing irrigation canal, new groundwater wells, groundwater treatment and supply, a hatchery and administration building, adult holding and spawning ponds, a new shop building, a waste treatment pond, and three 2,000-square-foot residences for hatchery staff. 

To understand the potential environmental impacts of this proposal, BPA is preparing an environmental impact statement (EIS) following the procedures of the National Environmental Policy Act (NEPA).  The EIS studies the impacts of constructing and operating the proposed hatchery, as well as a no-action alternative in which the hatchery is not constructed.  The EIS describes anticipated impacts to natural and human resources, as well as mitigation measures to help avoid or minimize impacts.  Throughout the NEPA process, BPA will continue to work with landowners, tribes, federal, state and local agencies, and interest groups.

BPA has published the final EIS, which includes responses to public comments received during the draft EIS
comment period.  Based on the analysis in the final EIS, BPA will issue a record of decision on any action we may take on this project
