Fishing Lake Michigan

Lake Michigan is a big, deep freshwater lake, and the fishing here runs on temperature, wind and the shape of the shoreline rather than anything like a saltwater current edge. There is no shelf break, no canyon and no Gulf Stream. What there is instead is a deep, cold lake that warms at the surface through the season, sets up a thermocline, and gets pushed around hard by the wind. Reading the surface temperature and the edges on the chart is how you find the water that holds bait and fish.

The defining feature on Michigan is wind driven upwelling and the way it moves the temperature around. The lake is big enough that a sustained wind along one shore will pile warm surface water up on the downwind side and pull cold deep water to the surface on the upwind side. Surface temperatures can swing by many degrees in a day, and the warm water, the cold water and the edge between them all shift with the wind. The salmon and trout here relate closely to temperature, so finding the band of water in their preferred range, and the edges where warm meets cold, is the heart of the plan. The SST layer is built to show exactly that.

In spring, the nearshore water warms first and a thermal bar can set up between the warming shallows and the cold offshore water, concentrating bait early in the year. As summer comes on, the thermocline sets up with depth and the fish follow the temperature layer, often suspended over deep water. Note that Michigan does not carry the ocean bathymetry depth readout that the saltwater coastal regions have, so use your own lake charts and electronics for depth.

Seasonally, anglers here typically target chinook and coho salmon, which are the signature fish of the lake, along with steelhead, brown trout and lake trout. The fish move with the temperature and the bait through the season, holding nearshore early and often moving offshore and suspending over deep water as the surface warms. None of it is guaranteed. Seasons, runs and regulations change every year, so always check current rules.

The habit that pays on Michigan is to read the surface temperature and the edges, pay close attention to what the wind has done, and set up on the band of water that is holding the right temperature.

What you get with ReelTemps

From the water

★★★★★
I've tried every temp map out there and they all feel like they were built ten years ago. I'm not exactly a tech guy, but this one actually makes sense the second you open it. First time using it, I marked a break in about 30 seconds the night before and boated bluefin right on it the next morning.

Used to burn half a tank driving around looking for color change or a solid temp break. Now I check ReelTemps before I leave the dock and I know exactly where I'm going. Less time driving around guessing, more time with lines in the water.

Albacore season used to mean a couple hours of homework the night before and just hoping it held up. Now I do most of my research that morning and pull it up on my phone if things change once we're out there. Makes calling an audible a lot easier.

Lake Michigan FAQ

Is Lake Michigan fished like a saltwater coast?
No. Michigan is a freshwater lake with no shelf break, canyon or ocean current edge. The fishing runs on water temperature, the thermocline, wind driven upwelling and the shoreline, so the temperature layer is what you read rather than a current break.
Why does wind matter so much on this lake?
The lake is big enough that a sustained wind piles warm surface water on the downwind shore and pulls cold deep water up on the upwind shore. Surface temperature can swing many degrees in a day, moving the warm water, the cold water and the fish with it.
What do anglers typically target on Lake Michigan?
Chinook and coho salmon are the signature fish, along with steelhead, brown trout and lake trout. They move with the temperature and bait through the season, holding nearshore early and often suspending over deep water as the surface warms. Seasons and regulations change, so check current rules.
Does this chart show depth contours for the lake?
No. The Great Lakes do not carry the ocean bathymetry depth readout that the saltwater coastal regions have. Use your own lake charts and electronics for depth, and use the temperature layer to find the right water.
