About Muskegon River

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

  • 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.

Sections

3 reaches

Croton Dam to Thornapple (Upper Gravel)

Wade & FloatSteelhead · Salmon · Brown Trout · Rainbow Trout

The classic tailwater head — cold Croton releases running over clean gravel bars, fast runs, and deep pools. This reach holds the best spawning gravel on the river and is the sight-fishing heart of the steelhead run, wide but with the most walk-in access. Croton Dam access, Kimble County Park, Pine Avenue, and Thornapple Road launches string the first six-plus miles below the dam.

Best for: Spring steelhead on the gravel with beads, small black stones, and egg patterns; fall Chinook salmon, coho salmon, and fall steelhead; resident brown trout and rainbow trout on the June hatches. Nymph, swing, and sight-fish.

Thornapple to Newaygo (Float Trout Water)

FloatSteelhead · Brown Trout · Rainbow Trout

Below Thornapple the banks go largely private and the river becomes big, structure-rich float water — the monster-trout reach. Wood along the banks, gravel bottoms, and outside turns hold the river's best resident fish. Wade access is limited to the launches and the gravel bars at Newaygo, so this is drift-boat and jet-sled water.

Best for: Resident brown trout and rainbow trout — the June hatches (Gray Drake at dusk, Sulphur, caddis, Isonychia), streamers for big browns, and nymphing between hatches. Also prime through the fall and spring steelhead runs.

Newaygo to Bridgeton (Lower River)

FloatSteelhead · Salmon · Rainbow Trout · Smallmouth

Below Newaygo the river widens further, warms in summer, and the trout fishery gives way to migratory runs and warmwater. A sand, cobble, and boulder mix, this is a staging and travel reach for fall salmon and steelhead more than a summer trout stretch — the honest truth is the trout water is upstream.

Best for: Fall Chinook salmon, coho salmon, and steelhead staging and running; summer smallmouth bass when the upper trout water warms.

Best seasons

Three windows drive the calendar: March through mid-May for the long spring steelhead run (the signature draw, peaking late March to early April on the gravel); June for the dry-fly peak, when Gray Drakes, Sulphurs, caddis, and Isonychia bring resident browns and rainbows up at dusk; and September into October for fall kings, coho, and the start of fall steelhead. It's a regulated tailwater, so it holds steadier than a freestone — the Croton gauge usually runs 1,000-1,300 CFS and roughly 900-1,600 fishes well. It doesn't truly blow out, but sustained releases well above 2,000 CFS make wading unsafe and cloud the sight-fishing gravel. The upper reaches stay cold all summer; below Newaygo the water warms through July and August and the trout give way to smallmouth.

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.

  • Open all year for stream trout, steelhead, and salmon on this Great Lakes tributary reach (Croton Dam downstream) — no inland-stream spring closure.
  • Snagging is prohibited — standard hook-and-line only; sight-fishing to spawning steelhead is a fair-hook game.
  • Artificial flies and bait both allowed under general Great Lakes tributary rules unless a gear restriction is posted on-stream.
  • Trout, steelhead, and salmon possession and size limits follow the statewide Great Lakes tributary tables — verify current-year limits before keeping fish.
  • Michigan fishing license required (age 17+); an all-species license covers trout and salmon.

Regulations and bag/size limits change annually — cross-reference the current Michigan Fishing Guide, on-stream signage, and Newaygo shop summaries before a trip.

Fly shops

  • Muskegon River Fly ShopNewaygo

Camping: Newaygo is the hub — fly shop, guides, lodges, ramps, food, and rooms mid-tailwater. Gray Drake Lodge sits on a river bluff; county parks (Kimble, Henning) and state land near Croton offer camping and river access.

No river access fee. Multiple public ramps and parks — Croton Dam access directly below the dam, Kimble County Park, Pine Avenue, Thornapple Road, and Henning Park/Newaygo City Park. The first 6+ miles below Croton hold the best walk-in wading; below Thornapple the banks go mostly private and it becomes a drift-boat reach.
