Steelhead fishing may be good throughout the winter when the weather warms, and the lower river near Cow Creek will probably be the best area for fishing until steelhead start moving upriver later in the spring. Fishing for trout and whitefish may also be good at times during the winter.

Anglers should remember that wild steelhead, Chinook salmon, and bull trout may be encountered in the Imnaha River. They cannot be harvested and must be released.
