Wild steelhead over 24-inches long may be harvested in the Illinois between Klondike Creek and Pomeroy Dam; 1 per day and 5 per year. Look for fishing to be good early in January in the Illinois. Fishing is restricted to artificial flies and lures. The Illinois River is open for trout fishing.

Since only hatchery trout may be retained, and hatchery trout are not likely to be to be found in the Illinois River at this time of year, fishing will be primarily catch-and-release for the native cutthroat trout.
