2020 Map of Sloan Reservoir

About this map

The Sacagawea River winds through this expanse of Fergus County, defining a landscape dominated by water management and high-plains drainage. This remote region is characterized by a series of significant catchments, including Sloan Reservoir and Lincoln Reservoir to the south, and Jordan Reservoir and Kosier Reservoir to the east. These features, along with Antelope Cr, suggest a land utilized for ranching or irrigation where water security is paramount. Human infrastructure is concentrated around crossings and tracks, most notably at Joslin Bridge. The area is navigated via established routes like Ridge Rd and the Wilder Trl, which follow the contours of the terrain rather than a strict grid, reflecting the practical necessities of travel in central Montana's open country.
