Abstract/Description or Keywords | Within the Columbia River Basin, the furthest upstream and northern-most extent of currently accessible anadromous salmonid habitat is found in the Okanogan River. The subbasin supports a stable population of summer-fall Chinook Salmon (Oncorhynchus tshawytscha), a greatly expanding number of Sockeye Salmon (Oncorhynchus nerka), a population of summer Steelhead which are considered threatened (NMFS 2009), and rare observations of spring Chinook Salmon and Coho Salmon (Oncorhynchus kisutch). During the late summer months, water temperatures in the mainstem Okanogan River frequently exceed 24?C, representing a challenging environment for salmonids (reviews in Currie et al. 1998 and Beitinger et al. 2000), which may cause adjustments in juvenile rearing location and adult migration during that timeframe. A number of small, cold water tributaries to the Okanogan River offer additional habitat, but access is often restricted by insufficient discharge and the total extent is often limited by geographic and man-made barriers. |
