Title: Supplement Analysis for the Watershed Management Program EIS (DOE/EIS-0265/SA-103) - Install Fish Screens to Protect ESA Listed Steelhead and Bull Trout in the Walla Walla Basin – Phase II

Abstract

Proposed Action: Install Fish Screens to Protect ESA Listed Steelhead and Bull Trout in the Walla Walla Basin – Phase II Minor Diversion Screen Installations. BPA is proposing to provide cost share for a program that will protect ESA-listed salmonid species in the Walla Walla River Basin through the installation of state and federally approved fish screen on over 300 water diversions in the Walla Walla River Basin. This program will involve a wide variety of projects including the installation of screens for both pump and gravity fed surface water diversions. This project will be implemented in conjunction with the Walla Walla County Conservation District, Columbia County Conservation District, Washington Department of Fish and Wildlife, Walla Walla Community College, Washington Department of Ecology, and local irrigators. ESA-listed steelhead and bull trout are presently at risk in the Walla Walla Basin as a result of a combination of factors that primarily involve insufficient flow, extensive habitat degradation, and mortality from surface water diversions. Unscreened or improperly screened diversions can damage fish scaling and induce stress, both of which can be lethal. They are also known to cause migration delays and increased predation; impinge fish against screen surfaces; or, in cases wheremore » screen mesh size is too large, allow juvenile fish to be drawn directly into functioning irrigation systems resulting in direct mortality. The goal of this project is to eliminate imminent mortality risks to ESA-listed fish arising from inadequate irrigation diversions in the Walla Walla Basin by upgrading screens to current state and federal juvenile fish screen standards.« less

  • BPA proposes to purchase approximately 310 acres of privately-owned land in the Yakima River Basin in Kittitas County, Washington as part of the Yakima River Side Channels Project. Title to the land will be transferred to the United States Government, Bonneville Power Administration for fish and wildlife habitat protection and enhancement. The goal of this project is to contribute toward the rebuilding of Yakima Basin spring chinook salmon and steelhead populations by improving survival during their first year of life. This will be accomplished by protecting and restoring off-channel rearing habitats associated with the mainstem of the Yakima River. Historically,more » these habitats have been severely degraded through the construction of transportation corridors, irrigation developments, and diking activities. The subject parcels are located near the Cle Elum reach of the Yakima River which contains a variety of aquatic and riparian habitats that support native fish, reptiles, and amphibians, as well as waterfowl. Conservation of these lands will contribute to the rebuilding of steelhead and chinook salmon runs in the Yakima River system. These lands are located in a portion of the watershed where a large percentage of the basin’s spring chinook salmon spawn. Upon hatching, young salmon fry move into the shallow areas along the river margins to begin their early growth. These parcels contain numerous shallow backwater channels and wetlands that are protected by a thick over-story of native trees and brush. These features are important for the development of the young fish during their first year of life. This project proposes to preserve these 310 acres in their natural condition, which will ensure that this critical fish rearing habitat is maintained in the future.« less
  • The proposed restoration and protection of the Big Canyon Creek Watershed will assist in the recovery and restoration of fish and wildlife habitat. All activities will take place within the ceded territories of the Nez Perce Tribe. Two activities are planned: road decommissioning and fence to prevent livestock access to sensitive wetlands and riparian areas.
  • The proposed restoration and protection of the Lapwai Creek Watershed will assist in the recovery and restoration of fish and wildlife habitat. All activities will take place within the ceded territories of the Nez Perce Tribe (See attached Project Area Map). Activities include placement of grade control weirs to allow fish passage, road decommissioning, and installation of fencing to prevent livestock access to sensitive wetlands and riparian areas.

Approximately 400 acres were included in the overall Scatter Creek/Plum Creek land acquisition proposal. This Supplement Analysis covers only the acquisition of the subject 61 acres. BPA is proposing to acquire the remaining property on a staggered schedule over the next two to three years. Additional land acquisition actions will require separate NEPA documentation. All required environmental and cultural resource surveys referenced in this Supplement Analysis were conducted on the total 400 acre area.« less
