Chris Izworski, reporting from Michigan on the current state of the Muskegon River this Friday morning in early July. The flow stands at 1,420 cubic feet per second, gauge height holding at 5.2 feet. These are comfortable summer numbers, neither skinny nor blown out, and the river is fishing with clarity below Croton Dam. The forecast carries heat today into the mid-80s with a chance of afternoon showers, then scattered storms rolling through tomorrow on Independence Day. This is textbook midsummer timing: the Hexagenia hatch has closed its brief, erratic window for another year, and the water has settled into its terrestrial rhythm.
The tailwater stretch below the dam is where most anglers concentrate effort this time of year, and for good reason. The cooler releases sustain brown trout and resident steelhead through the warmest weeks, and the fish remain active if you read the light correctly. Early mornings before the sun climbs high produce steady dry fly action on small terrestrials: black ants in size 16, foam beetles in size 14, and the occasional hopper along grassy banks. The brown trout are tuned to surface disturbance now. You will find fish holding in slack water along the current seams, especially near structure, waiting for the drift to bring something down. A well-placed hopper along the willows above Croton Pond can draw strikes from fish that have not moved all day.
What Is Emerging Now
The Hexagenia spinnerfall, which ran sporadically through late June, has ended. If you were waiting for one last night of the big bugs, that opportunity has passed. What remains are the Tricos, hatching in the slower water of the upper river and in tailouts below riffles. The spinner clouds form mid-morning, typically between eight and ten o’clock, and the trout rise selectively to the spent flies on flat water. A Trico Spinner in size 20 or 22, tied sparse with a split tail and clear wings, will match what the fish are seeing. This is technical fishing. Long leaders, light tippet, careful approaches. The fish are not large, but they are fussy, and the satisfaction of fooling them on a size 22 dry is considerable.
Terrestrials dominate the rest of the day. Hoppers are not yet abundant in the grasses, but they are present enough to justify carrying a few foam patterns in tan or yellow, sizes 10 through 14. Ants and beetles work better right now, fished tight to banks or dropped into pocket water behind boulders. A Black Fur Ant in size 16 or a simple foam beetle will take fish through midday when nothing else is moving on the surface.
Where to Go
The public access at Croton Dam offers the most direct entry to the tailwater. The water immediately below the dam holds fish year-round, though it can be crowded on holiday weekends. Walk upstream or downstream to find solitude. The stretch from Croton Dam down to Croton Pond is classic tailwater structure: deep runs, gravel bars, undercut banks, logjams. Work the edges and seams with terrestrials. If you prefer wade fishing with room to move, the upper river above Croton offers more space and less pressure, though the water warms faster and the trout become less cooperative by afternoon.
Sullivan Creek, entering below the dam, adds cold water and oxygen, and the confluence zone is worth attention in the mornings. Fish stack up there when the main stem warms. A small nymph rig with a Pheasant Tail in size 16 and a Zebra Midge dropper will produce if the dry fly action slows.
The Practical Read
Tomorrow is Independence Day, and the river will see traffic. Plan accordingly. If you prefer quiet water, fish early and be off by mid-morning, or wait until evening when the crowds have left. The weather forecast suggests afternoon thunderstorms both today and tomorrow, which can spark brief feeding windows as the barometric pressure drops. If storms build, get off the water, but watch for the lull afterward when trout resume feeding with urgency.
The Muskegon tailwater fishes well through July if you adjust your expectations. This is not spring dry fly season with prolific hatches and eager fish. This is careful fishing, observational fishing, where small offerings and precise casts matter. The fish are there, holding in predictable places, and they will eat if you show them something that looks natural in the drift.
