2014 Map of Willow Creek Dam

About this map

The Lodge Grass Storage Reservoir and the engineering of the Willow Creek Dam anchor this Montana landscape, illustrating the critical role of water management in Big Horn County. This 2014 survey reveals an intricate network of irrigation infrastructure designed to harness the drainage of the Bighorn Mountains. The Lodge Grass Feeder Canal and family-named waterworks such as the Robert Miller Ditch and William Miller Ditch trace the historical development of agricultural land use in the region. The terrain is defined by deep cuts such as Lodge Grass Canyon and the winding course of Lodge Grass Cr. These natural features, alongside numerous tributaries like Rotten Grass Cr and Jess Coulee, shaped the path of early rural roads like Sumac Rd as they navigated the local topography.
