We are approaching the best time of year for steelhead fishing on the Imnaha River. From mid-March through the end of April, fish will be moving through the lower Imnaha River up from the Snake River. Fishing can be good throughout the open section and fish can also be caught as they move up the lower portion of Big Sheep Creek. The last day of steelhead season on the Imnaha River and Big Sheep Creek is April 30th.

The best public access is downstream of Horse Creek. Anglers fishing upstream of Horse Creek to the town of Imnaha need to make sure they are aware of land ownership boundaries and always ask for permission before fishing on private lands.

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