About this water

The Muskegon below Croton is a big, even tailwater that holds enormous numbers of steelhead and a heavy fall salmon run. Because the dam steadies the flow, it fishes when the freestones are blown or frozen, and the steelhead winter in it in good numbers — a drift-boat river where you can fish a long way and read the dam, not the sky.
