OAR 635-500-0880: Trout

(1) The following operating principles apply to the Clackamas subbasin: (a) Trout in the Clackamas subbasin shall be managed for natural production. No hatchery trout shall be stocked in flowing waters of the Clackamas subbasin; and (b) Natural barriers to anadromous fish passage shall not be removed. Culverts and man-made obstacles may be improved to allow anadromous fish passage, if fish historically passed the barrier. (2) In accordance with these operating principles, it is the objective of the Department to: (a) Maintain the genetics and production of indigenous wild trout populations, by maintaining genetic diversity, preserving and restoring historical distribution, and by sustaining multiple-age classes; and (b) Reintroduce bull trout in the Clackamas subbasin to restore a self-sustaining population consistent with achieving the desired status of anadromous salmonid populations identified in the Lower Columbia River Conservation and Recovery Plan for Oregon Populations of Salmon and Steelhead (OAR 635-500-6575).
