The Shawnee Twin Lakes, on South Deer Creek in Pottawatomie County, is a municipal lake owned and operated by the City of Shawnee. Lake #1 was built in 1935, covers a surface area of 1,336 acres and has 16 miles of shoreline. Lake #2 was built in 1960, has a surface area of 1,100 acres and 9 miles of shoreline. The lakes are connected by a 10-foot-deep canal constructed in 1962. Shawnee residents approved a referendum in 1994 permitting full recreation on Lake Number 1, which includes swimming, skiing, and personal watercraft. A fully enclosed fishing dock provides year-round all weather-fishing. Isaac Walton Park, established after the opening of Lake # 1 in 1935, has 15 camp sites, 8 picnic areas with grills, swimming, restrooms, lighting, and parking lots. The Glen Collins Park (formerly Stonehenge) was developed by city crews, is located between the two dams, and has a picnic shelter, picnic areas with grills, swimming, restrooms, lighting and parking lots. When the water level declines during periods of drought, the city may suspend recreation. To inquire, contact the Shawnee Parks Department at 878-1529.
