Pacific Lamprey Artificial Propagation and Release Research (DOE/EA-2104)
Umatilla County, OR; Benton County, WA; Yakama County, WA; Walla Walla County; WA and Columbia County, WA

Bonneville Power Administration (BPA) is proposing to fund the effects of artificial propagation and out-planting of Pacific Lamprey larvae to further ongoing lamprey restoration research.  BPA would help fund the Confederated Tribes and Bands of the Yakama Nation (YN), the Confederated Tribes of the Umatilla Indian Reservation (CTUIR), Columbia River Intertribal Fish Commission’s (CRITFC) to evaluate the feasibility of using artificial propagation and out-planting techniques routinely used for hatchery-produced fish for rearing and releasing artificially-propagated lamprey. 

Proposed actions would include:

  1. Annual production and release of up to 300,000 early life stage larval lamprey in the Upper Yakima River, 150,000 in the Naches River, and 2000 juvenile (smolt) and late life stage larval lamprey in the Yakima and Columbia River Subbasins for assessment of migration and behavior.
  2. Annual production and release of up to 500,000 larval lamprey in the Mid Walla Walla and 1,000,000 pro-larvae in the Upper Tucannon River.  
  3. Evaluation and monitoring of released lamprey survival and migration to help determine the most successful strategy for population supplementation and to inform development of restoration actions.

To understand the potential environmental impacts of this proposal, BPA will prepare an Environmental Assessment (EA) under the National Environmental Policy Act.  The EA will describe anticipated impacts to natural and human resources and may include mitigation measures that would help avoid or minimize impacts. During this process, the agencies will work with landowners, federal, state and local agencies, interest groups, and Tribes.  The proposed schedule for the EA process is as follows:

Scoping comment period
Draft EA available for public comment
Final EA
Finding of No Significant Impact (if warranted)
If decision to proceed, implementation begins
​March 11, 2019 - April 11, 2019
Spring 2020
Summer 2020
Summer 2020
Fall 2020

BPA is considering comments received during the public scoping period while preparing the draft EA.
