2012 Map of Heggs Lake

About this map

Glacial depressions and marshy basins define this section of Clark County, dominated by the waters of Heggs Lake and Swan Lake along its northern edge. The landscape is a textbook example of the prairie pothole region, where drainage patterns are often internal and dictated by shallow lakes and wetlands like Pepper Slough and Lake Todd. This 2012 survey shows the highly structured section-line road grid that governs the rural territory, with 431st Ave and 433rd Ave cutting across the terrain to connect remote farmsteads. The concentration of water bodies, including Carson Lake, illustrates the vital role of natural hydrology in an area otherwise dedicated to expansive agriculture and section-based land management.
