1978 Map of Kennebec SE

About this map

The White River carves a deep, intricate drainage pattern across the lower half of this landscape, defining the topography of Lyman County. In the late 1970s, this area remained primarily open rangeland and prairie divided into townships such as Kennebec, Rex, Rose, and Edna. The map reveals a sparse but deliberate settlement pattern, centered on small water sources like Kennebec Lake and Jackson Lake. Significant geological relief is evident along the river bluffs, where numerous unnamed draws and ridges create a complex terrain before leveling out into the high plains. The presence of Wiesner in the western section, alongside drainage features like Bad Creek and Davis Creek, provides essential landmarks for understanding the rural distribution of homesteads and water management in this portion of South Dakota.
