Are you sure that is the official name ? Could be something else. I grew up on Browns Lake, and according to the DNR it is North Browns Lake. Didn’t know there was a south either ??? What county is it in ? You can pull up all the lakes of a county and sift through there too. Good luck.

Poked around, found Bear Creek Reservoir. There was this topo map only on DNR website, no lake map available there.
Don’t know if they still have them, but the park office used to have maps available at the little place you pay when first coming into the park. I could probably dig one up if they don’t have them available.
