It is the mission of the Columbia River Fisheries Program Office (CRFPO) to assist in determining the status of imperiled natural stocks, to evaluate management measures for recovery and assist in the recovery of these stocks, and to prevent future listings. The CRFPO's primary contribution to these activities is to design and implement monitoring and evaluation, coordination, and dissemination of fisheries information. The CRFPO also provides for science-based management of aquatic resources on federal and tribal lands in the area from the Columbia River mouth upstream to McNary Dam and in other areas throughout the Columbia River Basin that have been and continue to be affected by anthropogenic actions of a regional scale. Providing technical assessment, interagency coordination, and representation on technical and policy level workgroups, committees, councils, and commissions for hydrosystem, hatchery, harvest, and habitat management are the key work tasks for the CRFPO.
