1970 Map of Twomile Lake

USGS Topo · Published 1994

About this map

Fort Sisseton Military Reservation Boundary and Port Sisseton State Park dominate the southeastern landscape of this Marshall County survey, reflecting the area's transition from 19th-century military frontier to 20th-century preservation. The terrain is characterized by a dense network of glacial prairie potholes and sloughs, including Twomile Lake, Threemile Lake, and Fourmile Lake. This watery landscape provided critical habitat for waterfowl as evidenced by Mallard Slough and Cattail Lake. Local development is clustered around specific resource extraction points and community nodes, such as the Gravel Pits in the east and the Rose Hill Ch in the southwest corner. The map also delineates the civil boundaries of Waverly, Hamilton, Sisseton, and Fort townships, providing a clear picture of the rural South Dakota land division in the 1970s.
