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.

What would change the calculation
Cooler water — back toward the 10–16 °C ideal band — would lift the score and ease welfare.
A drop and clear would lift the flow and clarity scores.
The dawn and dusk windows score higher than the midday lull.
