I've caught a few at Lake St. Clair out of Oly.
On the west side of the park is a large parking lot where the boat launch and fishing dock are located. Duck Lake and the connecting labyrinth of canals are the perfect place for year-round bass, crappie and trout fishing. The park has an ADA men's and women's restrooms which are kept open until sunset. A port-a-potty is available by the boat launch 24 hours a day during the summer months.
