2021 Map of Bond Bottom

About this map

Lake Francis Case dominates this Missouri River landscape, following the winding boundary between Brule and Lyman counties. This modern topographic survey highlights the intricate drainage systems and dramatic relief of the Great Plains, where Fivemile Cr and Elm Cr carve deep draws into the surrounding bluffs. The map illustrates a preserved section of the river valley, featuring the low-lying Bond Bottom and the distinct elevation of Twin Butte to the southeast. Historically significant landmarks like Bailey Island remain visible within the reservoir, providing a clear view of how the waterway has shaped local topography and land use. The grid of rural roads, including Elm Creek Rd and 261 ST ST, provides access to these dissected hills and the sprawling riverfront.
