2021 Map of Heggs Lake

USGS Topo · Published 2021

About this map

Coteau des Prairies, a vast plateau rising above the surrounding plains, dictates the hydrology of this Clark County landscape. The area is defined by a dense concentration of glacial wetlands and prairie potholes, including Heggs Lake and Swan Lake in the north and the larger waters of Lake Todd and Carson Lake to the south. This network of seasonal and permanent water bodies, such as Pepper Slough, reflects the characteristic topography of the region, where internal drainage creates numerous basins across the rolling terrain. Human activity is largely organized around the section lines of the Public Land Survey System, with S Dakota Highway 20 and a grid of rural roads like 432nd Ave and 160th St providing access to the agricultural tracts between the lakes.
