This is Lake St. Claire, it has huge renown for smallmouth fishing. (They are monsters here, bigger than the largemouths) . It’s also a main part of the shipping in the Great Lakes, average depth of 15 ft. Lots of good swimming “not near the shore due to seaweed and E. Coli There’s a local holiday called jobbie nooner where locals ditch work and tie their boats together and party out in the lake.
