Acquisition: The original purchase of land was 1562 acres in 1930 by the Kansas Forestry, Fish and Game Commission. A 100 acre lake was constructed in 1932 and enlarged to 144 acres in 1955.

Area Description: The lake was constructed by building an earthen dam around an historic wetland formerly known as "Callahan Marsh". KMSL is spring fed with a sandy bottom and is well known for its clear water. It is a shallow impoundment averaging less than 4 feet in depth. The surrounding countryside is dominated by riparian woodlands and rolling sand prairie. The campground is well shaded by large cottonwoods. The lake is managed in conjunction with Byron Walker Wildlife Area and hunting is allowed on the western one-third of the lake.

Fishing: Channel catfish are the most popular species. Additional species include: black bass, crappie, northern pike, bluegill and redear sunfish. Boat launching facilities, fishing piers, and fish feeders are provided to enhance the fishing opportunities.

Camping: Primitive camping and picnicing facilities are provided for fishermen on the eastern shoreline of the lake. Picnic tables, fire rings, vault toilets and one picnic shelter are available. No water, electrical, or sewage hookups are available. Drinking water is not available on site.
