2017 Map of Red Lake West

About this map

The Missouri River corridor south of Chamberlain defines this portion of the South Dakota landscape, where the wide expanse of Lake Francis Case is framed by the rugged bluffs of the river valley. The boundary between Brule County and Lyman County follows the river's center, cutting through Bailey Island. The upland plains are organized by a rigid section-line road grid, including Hwy 50 and numerous numbered avenues like 347th Ave. Genealogists and local historians will find the Grandview Cem near 258th St, a quiet landmark in an area dominated by large-scale agricultural tracts and the winding drainage of Reimer Cr. The map illustrates the 21st-century configuration of the Missouri, reflecting the impact of mid-century damming projects on the original river channel and surrounding geography.
