Muskegon River
Insights
The Muskegon below Croton Dam is West Michigan's do-everything river — a wide, gravel-bottomed tailwater running roughly 35 miles from the dam down through Newaygo toward Bridgeton. Croton is a Consumers Energy hydroelectric dam, and its cold, steady releases are the whole story: they hold the upper river in a trout-friendly band year-round, keep it ice-free when the rest of Michigan locks up, and buffer the flashy runoff that blows out unregulated rivers. Because it's a utility dam, there's no federal reservoir data feed for Croton Pond — the page runs on the one USGS flow gauge just below the dam, which typically reads around 1,100 CFS. This is a big river by Michigan standards, over 200 feet wide in places, so it's drift-boat and jet-sled country more than a wade-anywhere creek, though there's genuine walk-in gravel below the dam.

| Species | Abundance | Best Season | Size | Notes |
|---|---|---|---|---|
| Steelhead | Primary | Mar-mid-May, late Oct-Dec | 5-12 lb, to 15+ lb | The headline fish and one of the longest spring runs in the Midwest. Spring peaks late March into early April on the gravel from Croton down to Thornapple; fall steelhead are strong by late October. Winter fish hold on the ice-free tailwater for the hardy. |
| Chinook Salmon (fall run) | Common | Sep-early Nov | 10-25+ lb | Fresh kings push in from Lake Michigan in early September and peak late September into early October. Big-water swinging and nymphing, best near the dam early in the run. |
| Coho Salmon | Common | Sep-Oct | 4-10 lb | Runs with the kings in fall — smaller but aggressive, and a good fly target when the water is a touch off-color. |
| Brown Trout | Common | May-Jun, Sep-Oct | 12-16" avg, trophies 24"+ | A strong wild and holdover resident population from Croton down to Newaygo, plus lake-run browns that enter in fall. Streamers move the big ones; the June hatches bring them up top. |
| Rainbow Trout | Common | May-Jun, fall | 10-18" | Wild and holdover resident rainbows hold year-round in the cold upper tailwater — distinct from the migratory steelhead, and the day-in day-out dry-fly and nymph fish. |
| Smallmouth Bass | Seasonal | Jun-Sep | 10-18" | Takes over the warmer water below Newaygo in summer when the trout hatches taper — the sensible warm-weather target on the lower river. |

Regulations
The Muskegon below Croton Dam is a Great Lakes tributary (anadromous) stream, so it stays open all year for trout, steelhead, and salmon — unlike Michigan's general inland-trout streams that close through the winter and early spring. Michigan DNR sets gear designations and run-fish rules; confirm current-year bag and size limits and any posted gear restrictions.
