2017 Map of Ecoffey Lake

About this map

Ecoffey Lake and the winding course of the Little White River define this portion of Bennett County, South Dakota. The landscape is characterized by its high concentration of surface water features, including Emma Springs and a series of smaller basins like Robinson Lake, Posey Lake, and the adjacent West Lake and East Lake. This survey illustrates the intricate drainage patterns of the region, where the river system and isolated lake beds reflect the local topography and groundwater levels. The map provides a clear look at the undeveloped prairie environment and the water sources that have historically supported ranching and land use in this part of the state.
