Hey Brandon,
Virtually all the southern Michigan muskie fishing has been provided by the DNR's stocking program. Go to <url url="[Permission to view this media is denied]
">** you do not have permission to see this link ** and select muskellunge. It takes about 7 or 8 years for the faster-growing females to reach 42 inches from the time that they are stocked in the fall at 10"-12". Some lakes are better than others but they should all have some decent fishing.

Belleville lost a lot of its fish over the dam making a unique fishery. There is decent fishing in the river even below Flat Rock. The DNR confirmed in a survey that the fish below these dams were indeed the ones stocked in Belleville.
