Summary Description: Photo-document native trout populatives in Wind, Big White Salmon, Little White Salmon, Klickitat, Rock Cr Yakima, Wenatchee, Entiat, Methow, Okanogan, Walla Walla, Touchet, Tucannon, Grande Ronde, Spokane, Crab, Kettle, Sanpoil and Pend Oreille subbasins

Background: The present state of knowledge regarding both the original post-glacial distribution and the present distribution/status of native populations of westslope cutthroat trout (Onchorynchus clarki lewisi), redband rainbow trout (Onchorynchus mykis gairdneri), and bull trout (Salvelinus confluentis) is disturbingly limited. Habitat alteration and hybridization with non-native strains of rainbow trout, and with introduced populations of Yellowstone Cutthroat trout, have similarly resulted in the significant loss of pure redband populations, including the mid- and upper-Columbia Basin in Washington State. Bull trout have suffered extensively from the same impacts. Fluvial and adfluvial populations have particularly labored under the impacts of loss of connectivity in their migratory pathways due to river regulation and the disruption of large river and lacustrine food chains by introduction of non-native char. Headwater resident populations constitute a major remaining outpost for the species throughout much of its range, including the Columbia Basin in Washington State. Many of these headwater populations are threatened by hybridization with introduced non-native brook trout.

Milestones: Contract 1998AP070901 for $51,200 was issued in 1998. Mod 1 added $49,216 in 1999. It covered field survery work on tributaries to the Pend Oreille river in the Colville and Kaniksu National Forests. It also covered field surveys on the West Fork of the Klickitat river and its tributaries on the Yakama Indian Reservation. 1998 Sampled 12 tributaries in Yakima/Naches subbasin; photo-documented and collected tissue samples for DNA analysis from 11 of these (the 12th had been taken over by brook trout (S. fontinalis).

Results: None identified.
