The possession season for bass opens statewide Saturday, May 27.
However, Lake St. Clair and the St. Clair River and the Detroit River, all open a few weeks later on Saturday, June 17.
Lake St. Clair is known for monster smallmouth bass, but also contains big largemouth bass.
Located near Detroit, LSC continues to support a very healthy bass population in the 2-6 pound range, with trophy smallmouth growing even bigger. 100 fish days are common, which is why this fishery is one of the most popular bass fishing lakes in Michigan.
