Chris Izworski’s daily Michigan trout report turns to the Platte River this morning, where a spring-fed gem flowing toward Lake Michigan near Honor is running considerably above its seasonal norm. The news is not encouraging for the angler planning a drive into northwest Lower Michigan today.

The USGS gauge is reading 165 cubic feet per second. That’s 141 percent of the historical median for August 20, well into the 75th percentile and climbing into territory that makes wading difficult and dangerous. The 30-year record shows a typical August day here sits around 117 cfs. What you’re looking at today is a river still carrying recent runoff, moving with purpose, and stripping away the clarity that makes the Platte what it is.

At 1.43 feet on the gauge, the water is up enough to murk the shallows where you’d normally be sight-casting to selective browns in gin-clear flow. The current is swift in the channels where the trout hold. This is not a day to make the drive unless you live close enough to justify an hour’s scouting for whatever pockets might still be fishable. The systematic conditions rating sits at Fair, which is Michigan Trout Report’s way of saying you can fish it if you’re stubborn, but the river isn’t cooperating.

Why the Water is High, and When It Might Drop

The Platte is spring-fed, which usually means stable flows and cold, clear water even in late August heat. But recent precipitation upstream has lifted the gauge above normal for this calendar date. The question is whether more rain is coming to keep it elevated.

The National Weather Service forecast for the next three days shows no significant rain in the Honor area. That matters. Without additional runoff, the spring flow should begin settling back toward normal by Saturday. If you’re flexible with your schedule, Saturday afternoon and Sunday morning may offer a different picture. The Platte responds quickly to drainage, and 48 hours of dry weather should push that gauge down toward the 120 to 130 cfs range, where the river becomes genuinely fishable again.

What the Hatches Look Like in High Water

Tricos are still the game in early August mornings on spring creeks. First light through 9 a.m., you’ll see those tiny spinners falling to the water, and the trout will be rising. Normally, this is where the Platte shines: crystal water, selective fish, CDC Trico Spinners in size 20 on 7X tippet, all the precision work that makes spring creek fishing addictive. Today, that clarity is compromised. The high water is pushing sediment through the system and widening the current lanes where trout actually feel safe to rise. You’ll miss fish you normally wouldn’t.

Terrestrials will fish better in these conditions. Beetles and ants along the grassy banks, hoppers in the heat of the afternoon, delivered close to the bank and allowed to sit or given a subtle twitch. When the water is off color and moving, trout trust the margins more than the open current. The banks are where you’ll find the most reliable takes.

The evening will bring white flies, Ephoron leukon, those dense swarms that turn late August into something almost magical. Your golden hour window runs from 7:13 p.m. to 8:43 p.m., when the light gets low and the bugs get thick. White Wulffs and White Comparaduns in sizes 12 and 14 will draw aggressive rises. But again, that clarity you’re counting on to see the swarm and read the rises will be compromised. The river is working against you.

Access and Regulations

The Platte has National Park Service access points at Haze Road, Brethren, and Honor. Much of the river runs through or borders Sleeping Bear Dunes National Lakeshore, which means you’ll need to understand both DNR and NPS regulations before you fish. Check current rules before you go. Access rules and seasonal closures can change, and the Platte isn’t the place to learn regulations the hard way.

The Bottom Line

If you’re not local, don’t make the drive today. If you are local and the itch is unbearable, scout the margins in late afternoon and plan to fish the white fly window in evening. Focus on undercut banks and the softer water behind structure where trout can hold without exhausting themselves in the current. Expect fewer fish and more disappointment than usual. Alternatively, wait until Saturday when normal flow returns and the Platte becomes the fishery it’s known to be.
