Walla Walla Basin Spring Chinook Hatchery Program (DOE/EIS-0495)

Umatilla County, Oregon and Walla Walla County, Washington


    The Bonneville Power Administration (BPA) proposes to fund the Confederated Tribes of the Umatilla Indian Reservation (CTUIR) to construct and operate a hatchery at an existing adult holding and spawning facility managed by the CTUIR. The proposed hatchery would be on the South Fork Walla Walla River near Milton-Freewater in Umatilla County, Oregon and would incubate and rear spring Chinook salmon. Spring Chinook were extirpated from the Walla Walla River basin in the early to mid-1900s. The proposed project would augment fish populations available for harvest and aid in establishing a naturally spawning spring Chinook population in the Walla Walla basin.

    To understand the potential environmental impacts of this proposal, BPA has prepared an environmental impact statement (EIS) following the procedures of the National Environmental Policy Act. The EIS analyzes two action alternatives and a no action alternative.

    Alternative 1 calls for the new hatchery to incubate and rear up to 500,000 yearling spring Chinook smolts for release in tributaries to the Walla Walla River in northeast Oregon and southeast Washington.

    In Alternative 2, the hatchery would rear the same fish as Alternative 1, but would also accommodate the rearing of 810,000 spring Chinook smolts for an ongoing Umatilla basin program. This alternative would transfer production of Umatilla spring Chinook from the existing Umatilla Hatchery near Irrigon, OR to the proposed new Walla Walla Hatchery to help alleviate water constraints at Umatilla Hatchery. The transfer would not change other aspects of the Umatilla spring Chinook program such as spring Chinook acclimation and release sites, and the Umatilla Hatchery would continue to produce other fish.

    Both Alternatives 1 and 2 would construct new incubation and rearing buildings and equipment, water treatment and delivery systems, auxiliary facilities, and new staff residences.

    The EIS describes anticipated impacts to natural and human resources and includes mitigation measures that would help avoid or minimize impacts. Effects of methods to more efficiently use water, including a pumpback system and water reuse systems, also are analyzed.


    BPA is evaluating the comments received on the draft EIS and preparing the final EIS.
