May 3, 2026. Across Michigan’s 62 gauged trout rivers, this week presents a tale of two states. The Upper Peninsula is running significantly high across most systems following spring snowmelt, while the Northern Lower Peninsula shows more variability, with several prime rivers at or near normal levels and a few running dangerously low. For anglers planning the week ahead, the choice is clear: target the stable northern Lower Peninsula streams where caddis and sulphur mayflies are building on schedule, or embrace the challenge of high, cold water in the UP if you prefer aggressive spring conditions.
Upper Peninsula: High Water, Cold Temperatures, Limited Options
The Upper Peninsula is experiencing significant runoff. Two rivers have crossed into blown-out territory. The Michigamme River is running at 293 percent of its median flow, essentially unfishable for technical trout work. The Tahquamenon River sits at 208 percent, also well beyond practical wading and fly-fishing conditions. Below that threshold, the Sturgeon River near Nahma is at 145 percent, the Cisco Branch Ontonagon at 168 percent, the Pine River near Rudyard at 157 percent, and the Menominee River at 141 percent. These are marginal at best for standard approaches.
The brighter news comes from rivers holding closer to normal flows. The Black River in the UP is at 94 percent of median, the Sturgeon River at 93 percent, the Ontonagon River proper at 121 percent, and the Salmon Trout River at 122 percent. The Silver River sits at 84 percent. These streams offer genuine fishing opportunity this week, though temperatures remain cold across the entire peninsula. The Salmon Trout River is the coldest reporting at 42 degrees Fahrenheit, with the Escanaba River the warmest at 43 degrees. That cold water will suppress insect activity and slow trout metabolism, so focus on deeper pools, slower edges, and earlier morning hours.
One concern: the Cedar River in the UP is running at just 58 percent of median, unusually low for early May. If you target that system, expect clear water and selective fish. Five gauges across the UP are currently offline, so conditions on unmeasured systems remain uncertain.
Northern Lower Peninsula: Stability and Selectivity
The Northern Lower Peninsula presents the stronger week for Michigan trout anglers. None of the 39 gauged rivers in this region are blown out. The AuSable River, Michigan’s most famous trout stream, is running at 120 percent of median, a healthy level that supports both wading and fly work. The Pere Marquette River is at 118 percent. The Jordan River is at 114 percent. The Muskegon River sits at 109 percent. The Pigeon River is at 102 percent. These are all solid, fishable flows.
Several rivers are running high but not unmanageable. The Manistee River is at 135 percent, the White River at 135 percent, the Clam River at 137 percent, the Looking Glass River at 157 percent, the Pine River in mid-Michigan at 131 percent, and the Pine River near Oscoda at 138 percent. The Looking Glass is the standout here at 157 percent; focus on the lower sections and slower water. The others are elevated but well within normal spring parameters.
Temperature data reveals important nuance. The Manistee River is the coldest reporting at 46 degrees Fahrenheit, while the Muskegon River is the warmest at 54 degrees. That 8-degree spread matters. Warmer water accelerates hatch activity and trout feeding. Expect better caddis and sulphur emerges on the Muskegon and its warmer cousins than on the colder Manistee, where insect timing will be slower.
Three northern rivers warrant caution. The Au Gres River is at 63 percent of median, the Wolf Creek at 65 percent, and most critically, the Tittabawassee River at 29 percent. The Tittabawassee is essentially unfishable right now; that reading suggests dam operations or unusual conditions upstream. Seven gauges are offline in the northern Lower Peninsula, so unmeasured systems may behave differently than historical patterns suggest.
Southern Lower Peninsula: No Data
The Southern Lower Peninsula generates no gauge data in the Michigan Trout Report network. Anglers targeting streams in that region should contact individual outfitters or conduct field reconnaissance to assess conditions.
Where to Go This Week
Target the Muskegon River or the Jordan River this week. Both are flowing at reasonable levels, 109 percent and 114 percent of median respectively, and the Muskegon’s 54-degree water temperature is the warmest in the northern Lower Peninsula. Caddis and sulphurs are hatching statewide in early May, and these systems have the conditions to show good emerges. If you want to avoid crowds and prefer the challenge of high water, the Sturgeon River in the UP at 93 percent offers near-normal flow and genuine opportunity. Avoid the Michigamme, Tahquamenon, and Tittabawassee entirely this week.
