Walloon Lake is a glacier-formed lake located in Charlevoix and Emmet counties, just southwestward from the northern tip of the Lower Peninsula of Michigan. It is now home to many vacation homes and cottages. Though the end of the west arm of the lake is less than 1 mile (1.6 km) from Lake Michigan, Walloon Lake's surface elevation is over 100 feet (30 m) higher. The Bear River drains from the east end of the lake in Walloon Lake village, winding east then north down to its outflow into Lake Michigan at the south end of Petoskey.
