Chris Izworski’s Michigan Trout Daily weekly overview for Sunday, July 19: here is what the gauges actually show across the state right now, and why this week is split between blown-out northern rivers and the narrowing window of opportunity in the south.
We are deep in terrestrial season. Hoppers, ants, and beetles dominate the diet. The midday heat is brutal; fish move to pocket water, deep runs, and shade. This is the week to fish dawn and dusk. And it is also the week when Michigan’s hydrological split becomes impossible to ignore. The Upper Peninsula and Northern Lower Peninsula have taken serious water in the past ten days. The state’s largest river systems are running high or blown out. Meanwhile, the Southern Lower Peninsula, unmeasured by our gauge network, sits in the background, likely running lower and warmer. Plan accordingly.
Upper Peninsula: High Water, Cold Shoulders
Two Upper Peninsula rivers are blown out: the Silver River at 277 percent of median flow and the Pine River at Rudyard at 277 percent. Both are unfishable. The Tahquamenon River is running high at 154 percent; wading will be difficult and swing-fishing marginal. Water color is likely off as well.
The middle ground offers better prospects. The Salmon Trout River sits at 116 percent of median, the Michigamme at 114 percent, and the Iron River at 95 percent. These three are fishable with patience and knowledge of structure. The Ontonagon River is surprisingly low at only 70 percent of median, making it one of the few sensible Upper Peninsula choices this week. The Black River in Schoolcraft County is at 77 percent. Both offer near-normal conditions.
The problem rivers, beyond the blown-out pair, are the Black River in the UP proper at 47 percent, the Sturgeon River at 58 percent, and the Cedar River at 34 percent. The Presque Isle River is critically low at 25 percent of median. These are essentially closed for the week.
Water temperatures in the Upper Peninsula range from a cold 54 degrees Fahrenheit on the East Branch Salmon Trout River to 70 degrees on the Presque Isle. Seek the colder drainages; they hold fish even in July heat. Four gauges are offline, so real-time confirmation before you drive is essential.
Northern Lower Peninsula: Blown Out Arterials, Pockets of Opportunity
The Northern Lower Peninsula is the story this week, and it is a complicated one. Two major systems are blown out: the Thunder Bay River at 285 percent of median and the Sturgeon River at 181 percent. Both are unfishable. Five more rivers are running high and marginal: the AuSable River at 137 percent of median, the Manistee River at 143 percent, the Pigeon River at 178 percent, the Rifle River at 177 percent, and the Trap Rock River at 154 percent. These are technically fishable if you know the system, but you will be fighting current, sediment, and congestion.
The near-normal tier is where this week lives. The Pere Marquette River is at 105 percent of median and holds promise. The Jordan River is at 121 percent, still wettable and sensible. The Pine River is at 103 percent of median, running true to form. The Platte River is at 123 percent, the Muskegon River at 84 percent, and the White River at 93 percent. These six offer genuine July fishing. They are your targets.
Avoid the low rivers entirely. The Little Muskegon at 36 percent of median, the Maple River at 35 percent, the Pine River in Mid-Michigan at 55 percent, the Bear Creek at 65 percent, the Wolf Creek at 57 percent, and the Pigeon River in Ottawa County at 49 percent are all summer-stressed. Water temperatures range from 56 degrees on the Manistee to 73 degrees on the Muskegon. The colder systems, like the Manistee and AuSable, will hold fish in deeper pools. Six gauges are offline in this region, so verification before travel remains critical.
Southern Lower Peninsula: The Blindspot
The Southern Lower Peninsula has no gauged rivers in the Michigan Trout Report network. You are flying without data. Based on regional precipitation patterns and the high flows in the north, assume moderate to low conditions. Seek spring-fed systems, deep holes, and early and late light. Fish small terrestrials. Expect midday blanks. Call ahead to your local shop.
Where I Would Go This Week
If I were planning a trip, I would head to the Pere Marquette River. It is at 105 percent of median, which means it is fishable and not crowded. The water is cold enough to hold fish in deep runs. Terrestrials will work. Fish early and late, focus on shade, and expect the bite to be honest if not explosive.
My second choice is the Muskegon River at 84 percent of median. It is the lowest of the large systems. It will run warm, but it is the best chance for a full day of active fishing in the Northern Lower Peninsula without fighting high water and mud. Grasshoppers and foam ants at dawn and dusk.
