1985 Map of Sloan Reservoir

USGS Topo · Published 1985

About this map

The Sacagawea River snakes across this Fergus County landscape, defining a region where water management was essential to high plains life in the mid-1980s. This survey documents a series of named catchments and reservoirs that supported local ranching and agricultural interests in the breaks of central Montana. Prominent features include the eponymous Sloan Reservoir, as well as Jordan Reservoir and Kosier Reservoir, which captured runoff in an otherwise arid terrain. To the south, Lincoln Reservoir and the drainage of Antelope Creek illustrate the reliance on these constructed water sources. The map's contour lines and drainage patterns reflect the complex topography of the prairie, showing how the land was adapted for livestock and resource management during this era.
