2012 Map of Little Moreau Lake

About this map

Little Moreau River winds through this Dewey County landscape, carving a drainage pattern across the plains of northern South Dakota. The topography is anchored by the Little Moreau Lake reservoir and the prominent Twin Buttes to the northeast. This area reflects the rural ranching character of the region, highlighted by the presence of Rubendall Ranch near the northern boundary. A network of county roads, including Whitehorse Rd and several numbered routes like Co Hwy-5A, provide the primary infrastructure for this sparsely populated territory. The map illustrates the relationship between the river's seasonal flow and the established ranching homesteads that depend on these local water sources.
