Maple Lake is a mesotrophic (moderately fertile) basin located in southern Douglas County between Alexandria and Glenwood. It is connected to lakes Reno and Turtle via non-navigable culverts under State Highway 29. Maple Lake is moderate in size and relatively shallow. It has a maximum depth of 78 feet but almost half of the lake is less than 15 feet deep. Two public accesses are present on this lake. Largemouth bass, northern pike, bluegill, and crappie are all common in this lake, although, don’t expect to catch many trophy-sized fish. There are some big fish in this lake, but most of the game fish in Maple Lake do run on the smaller side.
