2021 Map of Lake Parmley

About this map

Lake Parmley and the winding course of Snake Creek dominate this corner of the South Dakota prairie along the Edmunds and Brown County line. The landscape is defined by the Jeffersonian grid, with a dense network of section-line roads like 372nd Ave and 131st St providing access to the fertile agricultural lands of the James River Valley. Near the lake’s southern shore, localized development is evident through smaller residential thoroughfares such as Maza Trl, S Shore Dr, and Sunset Dr. This 2021 survey illustrates the modern rural infrastructure of the region, where the natural hydrology of Snake Cr continues to influence the layout of land boundaries and transit routes across Township 123 North.
