Ice Fishing

The Au Sable is a flowing river, so ice conditions are highly variable and unreliable. Some of the dam impoundments like Mio Pond may freeze enough for ice fishing in cold winters, but moving river sections remain open or develop dangerously thin ice. Always check local conditions and exercise extreme caution.

Frequently Asked Questions

What fish are in the Au Sable River?

The Au Sable is one of Michigan's top trout streams. The upper river holds brown trout, rainbow trout, and brook trout year-round. Lower sections below the dams also hold walleye, smallmouth bass, and panfish. Fishing regulations vary significantly by river section — check the DNR regulations carefully, as some stretches are flies-only or catch-and-release.
