The Tongue River and its complex network of tributaries define the borderlands of Sheridan County, Wyoming, and Big Horn County, Montana. This landscape is a labyrinth of seasonal watercourses and topographic depressions, where family and local ranching history is etched into the terrain via names like Krenzien Draw, Heppner Draw, and Enochs Draw. The reliance on water management in this arid ranching country is evident through infrastructure like Gorman Reservoir Number 2 and the Prairie Dog Ditch Number 13, which divert flow from Prairie Dog Cr to support the surrounding high-plains acreage.
