1968 Map of Moreau SE

USGS Topo · Published 1971

About this map

The confluence of the Moreau River and the Lake Missouri Oahe River dominates this landscape, reflecting a period of significant hydrological change along the Missouri River system. The map captures the flooded river valley at a normal pool elevation of 1608 feet, where former terrestrial features are submerged or transformed into peninsulas and inlets. The Cheyenne River Indian Reservation Boundary cuts diagonally across the reservoir, marking a clear administrative division between Dewey and Walworth counties.
