2012 Map of Deaver Reservoir

About this map

Frannie Oil Field and the Polecat Oil Field define the industrial footprint of this Wyoming landscape, where energy extraction meets an extensive network of human-engineered irrigation. The desert terrain is transformed by the Frannie Canal and Deaver Canal, which channel water across the high plains to reach the Deaver Reservoir and smaller features like Blue Lake. This intricate plumbing of the Big Horn Basin is visible alongside historical transit routes like the Jim Bridger Trl. The map documents a complex balance between the natural drainages of Cottonwood Cr and Polecat Cr and the heavy infrastructure required for modern ranching and petroleum production in Park and Big Horn counties.
