Anyone know of a good fishing lake where you can rent small boats in Michigan?

I live in Genesee County, Michigan. (Flint to be exact.) I’m looking for some good fishing spots in the nearby area. Does anyone know of some good spots in the Genesee, Lapeer, Shiawassee County area or anywhere else? I’m particularly looking for lakes that might have small boat rentals available? Anyone have any ideas? I’d greatly appreciate any names of places that I could check into. THANKS
