About this map

The Moreau River meanders across this northern South Dakota landscape, shaping a terrain defined by complex drainage networks and tribal infrastructure. Recorded in 2017, the map illustrates the significance of water and community markers in Dewey County, where seasonal creeks like Handboy Cr and Veo Cr feed into the river system. To the northeast, the presence of Lake Oahe marks the impact of modern reservoirs on the local geography.

Local history and genealogy are centered on rural church sites and burial grounds, notably the Saint Marys Church Cem near the river and the UCC Cem further north. Transportation through this section of the Cheyenne River Reservation is facilitated by Bureau of Indian Affairs routes, including Bia HWY 3 and Bia HWY 4, which connect isolated landmarks and water features such as Blue Beaver Cr and Johnson Cr.
