2024 Map of Cannon Ball SE

About this map

The Missouri River and the expansive Lake Oahe dominate this Missouri Plateau landscape, marking the significant boundary between Emmons and Sioux counties. The settlement of Cannon Ball lies on the western bank, where the terrain is carved by numerous coulees and drainage ways including Beaver Holes Creek and Fool Bear Creek. This modern survey reveals a quiet, high-plains geography where land use is oriented toward the river and several protected natural spaces like the Emmons County Waterfowl Production Area. Genealogy and local history are anchored by several small burial sites, including the Saint James Episcopal Cem, Old Catholic Cem, and the Big Lake Cem near the lake's edge. The eastern uplands are defined by a grid of rural roads such as S Big Lake Rd and Bayside Dr, illustrating the sparse but persistent settlement pattern of the region.
