About this map

Lake Oahe dominates this part of Dewey County, where the massive reservoir floods the Missouri River valley and creates a sprawling, jagged shoreline of inlets and points. Several drainage systems converge here from the west, including the winding channels of Pascal Cr, Parker Cr, and Bull Cr. These tributaries carve deep into the Missouri Plateau before meeting the main body of the lake. Transport across this sparsely settled landscape is defined by local routes such as Bia Hwy 8 in the northwest corner and rural sections like 167 St and 169th St to the east. The map illustrates a modern era of water management and rural infrastructure, where the vast expanse of the reservoir has reshaped the original prairie drainage patterns of Alberts Cr and its neighbors.
