1970 Map of Lake De Smet East

USGS Topo · Published 1973

About this map

Lake De Smet dominates the northwestern landscape of this Johnson County quadrangle, showing the character of Wyoming water management in the early 1970s. The map illustrates a complex network of man-made waterways designed to harness the drainage of the eastern Bighorn Mountains foothills, including the Lake De Smet Canal, Last Chance Ditch, and Redman Ditch. These irrigation features crisscross the terrain alongside natural drainages like Boxelder Creek and Rock Creek, which eventually feed into Clear Creek at the southern edge of the sheet.
