Weekly AI Outlook as of 06/05/26
Muskegon's running at 634 cfs — perfect summer levels for wading and stalking resident browns in the tailwater section. Peak June means multiple overlapping hatches: sulphurs and caddis are in full swing, with the massive hex hatch approaching as water temps climb toward 60°F. Focus midday on sulphur emergers in the slower water below Croton Dam, then switch to elk hair caddis for evening risers. No recent shop intel — outlook based on current conditions and seasonal timing.
- Flow: 634 cfs — ideal summer levels for wading, excellent visibility and good holding water throughout the tailwater section
- Hatches: Sulphurs peaking midday #16-18, caddis building for evening emergence. Hex hatch imminent as water temps approach trigger point
- Water Temp: Tailwater staying cool despite 80°F air temps, but warming trend puts us near hex emergence threshold of 60°F
- Best Window: 11am-2pm for sulphur activity, then 6-8pm as caddis and evening risers become active on the lower section

About this Water
- Tailwater
- Best months: Year-round; peak Oct–Nov & Mar–May (steelhead)
The Muskegon River below Croton Dam in western Michigan is one of the Great Lakes region's premier steelhead and salmon fisheries. Cold releases from the dam create year-round trout habitat, with steelhead running from Lake Michigan in fall and spring and king salmon in late summer through fall. The Croton Dam to Newaygo stretch produces the most consistent fishing. Float trips dominate the productive water; wade access is limited to specific sites.
The Muskegon below Croton Dam is one of the largest and most consistent Great Lakes-run steelhead tailwaters — comparable in scale and productivity to the more-famous Salmon River in New York.

The Muskegon River is Michigan's most productive steelhead stream. Lake Michigan steelhead enter in fall with a major push in October, then again in March–April for the spring run. The lower river below Croton Dam provides extensive wade and boat access.
Productive Patterns
- Clouser Minnow #4–8
- Egg Sucking Leech #4–8
- Skunk Wet Fly #4–8
- Muskegon Special #4–8
Technique
Swing traditional wet flies through the runs and pool tails. Dead-drift egg patterns and nymphs in the deeper slots. The Muskegon's accessibility makes it Michigan's most-visited steelhead river.
Seasonal Notes
Lake Michigan steelhead migrate into the Muskegon on fall rains. Peak fall fish are October. Spring run begins late February. Fish drop back to the lake by May. Egg patterns, Hex nymphs, and beadhead stoneflies dead-drifted through runs near spawning gravel.
January Outlook
January on the Muskegon is winter steelhead season. The tailwater below Croton Dam keeps the river open and temperatures in the low 40s. Winter steelhead are present in the lower sections.
Productive Patterns
- Egg Pattern
- Nymph
- Streamer
- Soft Hackle
Tips
The Muskegon's tailwater effect from Croton Dam keeps it ice-free and steelhead-productive in January. The lower sections near Newaygo hold winter steelhead. A quality winter steelhead fishery when other Michigan rivers are locked in ice.
Water Notes
Regulated 500–1,500 cfs. Water 40–46°F. Tailwater keeps river open in Michigan winter. Winter steelhead available.

February on the Muskegon is productive for winter steelhead below Croton Dam. The river is more accessible and less variable than Lake Michigan tributaries without tailwater influence. Nymphing with eggs and large nymphs.
Water Notes
Regulated 500–1,500 cfs. Water 40–46°F. Prime winter steelhead conditions on this tailwater.
March Outlook
March spring steelhead peak on the Muskegon. Fresh fish entering from Lake Michigan combined with the tailwater's resident steelhead make March one of the best months.
Productive Patterns
- Egg Pattern
- Stonefly Nymph
- Streamer

Tips
The Muskegon's spring steelhead run is one of Michigan's finest. The section below Croton Dam is wade-accessible and productive. Guide floats provide access to the best holding water downstream.
Water Notes
Regulated 600–2,000 cfs. Water 42–50°F. Spring steelhead peak season.
April Outlook
The Muskegon River in Michigan is a steelhead and salmon river with excellent trout fishing as well. Spring steelhead runs peak in April.
Productive Patterns

The Muskegon's spring steelhead run typically peaks from late March through April. The section below Croton Dam is wade-accessible and productive.
Water Notes
Regulated flows 500–2,000 cfs from Croton Dam. Water 42–50°F. The tailwater effect creates consistent conditions for steelhead and trout alike.
May Outlook

Productive Patterns
- Elk Hair Caddis
- PMD Sparkle Dun
- Soft Hackle
- Stonefly Nymph
Tips
May transitions the Muskegon from steelhead to resident trout season. The Caddis hatch begins in late May and the first Sulphur activity appears. The section between the two dams holds quality resident fish.
Water Notes
600–1,500 cfs. Water 50–58°F. Steelhead run winding down. Resident trout season beginning.
June Outlook
