About this map

The Big Bend of the Missouri creates a dramatic u-shaped loop where the river channel winds through the rugged breaks of Hughes and Lyman counties. This massive hydrological feature is largely defined by the presence of Lake Sharpe, a reservoir that occupies the valley floor. The surrounding uplands are dissected by numerous drainages, including Joe Cr, Chaney Rush Cr, and Arrowhead Spring Cr, which carve through the high plains topography. A sparse network of local tracks and section roads, such as Carmody Rd and Westbend Rd, provides access to the ranchlands and river bluffs. This survey illustrates the contrast between the vast open water of the reservoir and the intricate coulees of the Missouri River trench, a landscape shaped by both natural drainage and modern damming projects.
