2015 Map of Oacoma

About this map

Oacoma sits at a strategic bend of the Missouri River in Lyman County, serving as a gateway where Interstate 90 crosses the water. This 2015 survey illustrates the modern landscape of the Missouri valley, dominated by the massive Lake Francis Case reservoir. The town's layout is centered around E Main St and E 1st St, with the Oacoma Cem positioned just north of the residential center. Several major tributaries converge near here, including the winding American Crow Cr and its N Fork American Crow Cr, which carve through the bluffs. To the south, the White River joins the main Missouri channel near Bird Island. The transition from riverine islands like Bice Island to the higher plateau reached via Cooper School Rd shows the dramatic elevation shifts characteristic of this region's river breaks.
