Lake Langdon in Mound, Minnesota, has an area of 144 acres (0.6 km²). Minnehaha Creek Watershed District (MCWD) charts show its maximum depth of 38 feet (12 m), though it would be classified as a shallow lake with a mean depth of 8.3 feet (2.5 m). It is named for R. V. Langdon, the first township clerk. It is located west of Commerce Boulevard and south of Lynwood Boulevard. Boats on the lake cannot navigate to the nearby Lake Minnetonka, though it overflows into Lost Lake, part of the Big Lake, through Langdon Bay Creek. It also serves as an outlet for Saunders Lake, to its west.
