Colvilles Okanogan Tribal Resource Management Plan

NMFS has evaluated one Tribal Resource Management Plan (TRMP, or Tribal Plan) submitted by the Confederated Tribes of the Colville Reservation (CTCR) to NMFS pursuant to the limitation on take prohibitions for actions conducted under Tribal Plans promulgated under the Endangered Species Act (ESA).

The Tribal Plan describes actions involving fisheries, hatchery production, predator control, kelt reconditioning, and associated monitoring and evaluation in the Okanogan Basin and Columbia River mainstem. The Tribal Plan is intended to contribute to the recovery of the steelhead population in the Okanogan Basin, and to responsibly enhance fishing opportunity of non-listed Chinook salmon in the Columbia River Mainstem and Okanogan Basin.

The programs described in the Tribal Plan would be operated in such a way as to minimize potential risks to ESA-listed natural-origin Upper Columbia River (UCR) spring Chinook salmon and steelhead populations. These potential risks include interactions between hatchery-origin and natural-origin fish that may lead to adverse effects. Of primary concern are genetic and ecological effects resulting from these potential interactions.

As part of the Tribal Plan, monitoring and evaluation would be implemented to assess the CTCR’s performance in meeting population conservation or harvest augmentation objectives, and their effects on ESA-listed natural-origin UCR spring Chinook salmon and steelhead. Information gained through monitoring and evaluation will be used to assess whether the impacts of the programs on listed fish are as expected. NMFS and the co-managers will annually review monitoring and evaluation results to evaluate whether assumptions regarding Tribal Plan effects and analyses remain valid, and whether the objectives of the Tribal Plan are being accomplished. The Tribal Plan includes provisions for annual reports that will assess compliance with performance standards established through the plan. Reporting and inclusion of new information derived from research, monitoring, and evaluation activities described in the plan provides assurance that performance standards will be achieved in future seasons.
