Homeowners and visitors are served by the unincorporated community of Curtis, Michigan, located on an isthmus that divides South Manistique Lake from Big Manistique Lake directly to the north.[1]

A 1.5-mile-long (2.4 km) spit of glacial gravel, left behind by some long-forgotten Ice Age glacier, projects from South Manistique Lake's western shore out into the lake. Not surprisingly, it is called "Long Point." An islet, Norton Island, can be seen near the lake's southeastern shore.[1]

As with other Upper Peninsula lakes, South Manistique Lake is known for its fishing. Local guides point fisherfolk toward muskie, smallmouth bass, and the lake's self-sustaining population of walleye. The lake's average depth is 10 feet (3.0 m), and its maximum depth is 29 feet (8.8 m).[2]
