FreeFishFishing in Michigan: inland lake depth maps and where to start
From inland lakes to the Great Lakes shoreline, how to use Michigan's lake depth maps, notable waters, and where to find the official rules.
Michigan touches four of the five Great Lakes and has thousands of inland lakes, so it offers almost every kind of freshwater fishing. The Michigan Department of Natural Resources publishes depth maps for many inland lakes, and NOAA charts cover the Great Lakes waters around the state.
What you can fish for
Inland lakes hold walleye, northern pike, muskellunge, largemouth and smallmouth bass, bluegill, crappie and yellow perch. The Great Lakes add salmon, lake trout and steelhead, and Michigan's rivers are known for trout and seasonal runs of salmon and steelhead.
Waters to know
- Houghton Lake: Michigan's largest inland lake, a shallow, weedy lake popular for walleye, pike and panfish, and a classic ice fishing destination.
- Lake St. Clair: between Lake Huron and Lake Erie, famous for smallmouth bass and muskellunge.
- Burt, Mullett and Torch lakes: large, clear northern lakes with deep water, where depth maps are especially useful.
- Saginaw Bay: an arm of Lake Huron known for walleye and yellow perch.
Using Michigan depth maps
Michigan's inland lakes range from shallow, weedy lakes to deep, clear glacial lakes with steep drop-offs. On weedy lakes, focus on weed edges and the first break. On deep, clear lakes, look for points, humps and steep breaks where fish can move between shallow food and deep water. In summer, the thermocline on deeper lakes often sets the depth fish use.
For the Great Lakes, FreeFish shows NOAA nautical charts. They are excellent for understanding reefs and drop-offs, but conditions on big water change quickly, so always check the marine forecast.
Through the seasons
In spring, inland lakes warm quickly in shallow bays, drawing panfish and bass, while rivers see steelhead runs. Summer pushes walleye and bass to weed edges and deeper breaks, and Great Lakes anglers troll for salmon and trout. Fall brings salmon up the rivers and a strong walleye and pike bite on inland lakes. Winter means ice fishing on inland lakes and protected bays, with perch, panfish, walleye and pike all popular.
Before you go
Michigan regulations vary by water type, including inland lakes, trout streams and the Great Lakes, and some waters have special rules. Trout and salmon fishing can require additional permissions. Check the official regulations linked below, and read our licensing guide if you are new to fishing in the state.
