2017 Map of Little Moreau Lake

About this map

The Little Moreau River carves a winding path through the high plains of Dewey County, defining the drainage patterns of this sparsely settled landscape. This 2017 survey shows a region where human impact is primarily defined by a sparse grid of county roads, including Co Rd 5k and Co Rd 5a, which follow the section lines of the Public Land Survey System. The topography is punctuated by prominent landforms such as Twin Buttes in the northeastern quadrant, serving as traditional navigational landmarks in an area dominated by open range and coulees. Central to the map is Little Moreau Lake, a significant water feature that provides a focal point for the surrounding terrain. The map details the transition between townships T16N R24E and T16N R25E, illustrating the precise legal boundaries that have shaped land ownership and use in this part of South Dakota for generations.
