2021 Map of Promise

About this map

Promise is the focal point of this Dewey County landscape, situated on the high ground overlooking the expansive waters of Lake Oahe. The settlement pattern is defined by the network of local routes like Promise Rd and BIA Hwy 4 that connect the community to the surrounding drainages. Genealogy researchers will find the Promise Cem clearly marked west of the main settlement. The terrain is deeply dissected by numerous creeks, including Virgin Cr, Beaver Cr, and Left Hand Bear Cr, which carve through the plains to reach the reservoir. To the north, Tom Hill Cr and Du Charme Cr feed into the northern reaches of the lake. This survey documents the intersection of modern infrastructure and the natural hydrological systems that shape life in this part of South Dakota.
