BPA invites you to comment on the draft Environmental Assessment of a project we're proposing to fund. Please see the project's webpage for the draft EA document. PROJECT DESCRIPTION: Bonneville Power Administration (Bonneville) is proposing to fund a program to evaluate the feasibility of artificial propagation and release for early life stage (egg, prolarva, larva, and juvenile) Pacific lamprey in the Yakima, Walla Walla, and Tucannon subbasins. This program would be implemented by the Confederated Tribes and Bands of the Yakama Nation (YN), the Confederated Tribes of the Umatilla Indian Reservation (CTUIR), and the Columbia River Intertribal Fish Commission (CRITFC) and is designed to be a scientific experiment that would evaluate the feasibility of using artificial propagation techniques as future enhancement actions for Pacific lamprey in the Columbia River Basin. Existing facilities at the Water and Environmental Center (WEC) facility at Walla Walla Community College and at Prosser Hatchery would be used to spawn adult lamprey and incubate/rear fertilized eggs to the desired life stage prior to release. Following release, lamprey would be monitored to determine habitat use, growth, densities, movements, and survival over the next 5-10 years. Releases of early life stage lamprey would occur in the spring (April/May/June/July) and fall (September/October). Post-release monitoring at release sites would be monitored twice soon after release to evaluate any movements or significant mortality. After that, release sites would be monitored annually.
