Abstract: The Coldwater River is a major tributary of the Nicola River, with its confluence at Merritt, in the southern interior of British Columbia. The Coldwater drainage presently supports populations of chinook and coho salmon, rainbow (steelhead) trout, Dolly Varden char and a number of non-salmonid species. In the summer-early fall period of 1977 and 1978 the Fish and Wildlife Branch undertook an intensive biophysical evaluation of the mainstem Coldwater River and several larger tributaries. Investigations were prompted by 1) proposed development of a major new highway between Hope and Merritt passing through portions of the Coquihalla and Coldwater River valleys, and 2) the need to identify potential fisheries enhancement opportunities, particularly for steelhead trout, relative to the federal-provincial Salmonid Enhancement Program (SEP). Classification of the mainstem environment was undertaken by stratifying gradient and associated physical habitat qualities. Nearly 95% of the first 78 km of mainstem features
