Lone Star Lake, 185 acre lake located in Kansas

Lone Star Lake is a 185-acre (75 ha) lake in Douglas County, Kansas, southwest of the unincorporated community of Lone Star. Douglas County owns and operates the lake and the surrounding Lone Star Lake Park, which has camping, picnic shelters and a swimming beach.

Construction began in 1934 by the Civilian Conservation Corps during the Great Depression and was completed in 1939. In the 1980s, improvements were made to water quality under the Clean Lakes Act, and around 2000 the dam was extensively rebuilt to address erosion damage.

The lake is named after the unincorporated community of Lone Star to its northeast. Douglas County owns and operates both the lake and the surrounding park, which offers camping, picnic shelters and a swimming beach. The Civilian Conservation Corps began digging the lake in 1934 for the Forestry Fish and Game Commission.

The lake sits roughly 2 kilometers southwest of Lone Star and is accessible year-round. Visit during warmer months for swimming, though the lake serves walkers, picnickers, and boaters across all seasons.

The lake was built by the Civilian Conservation Corps starting in 1934 for the Forestry Fish and Game Commission, which could not keep financing the work and handed the project to Douglas County in 1937. The county finished the lake in 1939 and still owns and runs it with the surrounding park.
