2020 Map of Antelope Creek Reservoir

About this map

Antelope Cr Reservoir and Upper O'Dell Coulee Reservoir sit as critical water management points within this drainage basin in McCone County. The landscape is defined by its coulees, which serve as natural catchment areas for various watercourses, including Preacher Coulee, Fullers Coulee, and Browns Coulee. This high-plains terrain is etched by seasonal and perennial flows such as Antelope Creek, Sand Creek, and Crow Creek. The sparse road network, featuring Mendenhall Rd, Sorley Rd, and N Sand Creek Rd, reflects the low population density and large-scale land divisions typical of this region's ranching economy. The map provides a clear look at the Public Land Survey System grid, illustrating how townships like t26n r46e and t25n r47e were carved out across the eastern Montana prairie.
