2017 Map of Platte Lake

About this map

The lowlands of southeastern South Dakota define this landscape, where the seasonal waters of Platte Lake and the smaller Lake Sixteen occupy shallow depressions in the prairie. This 2017 study illustrates the intersection of Brule and Aurora Counties, a boundary marked by the straight line of Co Rd 3. The area's drainage is primarily influenced by Platte Creek, which meanders south from the lakebed through a series of sections including T102N R66W. This map documents a sparsely settled agricultural region where transportation is dictated by a rigid section-line grid, featuring thoroughfares such as 367th Ave and 254 St. The layout provides clear evidence of the Public Land Survey System's enduring impact on the modern rural road network in this part of the state.
