The Mid-Columbia Fish & Wildlife Conservation Office provides technical fisheries assistance and cooperates with Service programs; other federal, state, and local agencies; tribes, and various entities to conserve aquatic species and their habitats in the mid- and upper-Columbia River Basin.

About Us

Our office meets U.S. Fish and Wildlife Service goals and responsibilities in the Columbia River basin from McNary Dam in the south to the Canadian border, including the Yakima, Wenatchee, Entiat, Chelan, Methow, and Okanogan basins and the areas above Chief Joseph Dam.

The National Fish Passage Program provides financial and technical assistance for projects that improve the ability of fish or other aquatic species to migrate by reconnecting habitat that has been fragmented by a barrier such as a dam or culvert. U.S. Fish and Wildlife Service biologists...

Projects and Research

We have four programs:

  • Yakima Basin Program: We focus on monitoring and evaluation, bull trout trapping and hauling at Bureau of Reclamation dams, mussel monitoring, improving instream flows, restoration, protecting existing high-quality habitat, and providing fish access to headwaters.
  • Native Fish Conservation Program: We evaluate and monitor bull trout, Pacific lamprey, and other understudied aquatic species to evaluate the status of populations and assist with conservation efforts. 
  • Hatchery Evaluation Program: We look for ways to optimize the performance and contribution of the fish we raise in our hatcheries.
  • Habitat Restoration Program: We work cooperatively with our partners to enhance and restore aquatic habitats through innovative techniques and best available science for the benefit of our native species in the Mid- and Upper Columbia.
