About this map

Fort Peck Lake and its northern inlets dominate this Missouri River breaks landscape in Valley County. The northern shoreline is deeply indented by Eighth Coulee Bay, where the drainage of Middle Eighth Coulee meets the reservoir's edge. The surrounding high ground is defined by a series of prominent landforms including Mid Eighth Ridge, Sixth Ridge, and Seventh Ridge, which separate the various coulees feeding toward the water.

Remote upland water management is evident through a network of small catchments such as Tiger Reservoir, Magruder Reservoir, and Stebley Reservoir. Historically significant landmarks like Graveyard Hill stand above the Upper Eighth Coulee, while transit across these heights is limited to routes like Shuffield Rdg. The map illustrates the complex intersection of high prairie ridges and the flooded drainage basins created by the nearby dam.
