1985 Map of Kachia Reservoir

USGS Topo · Published 1985

About this map

Kachia Reservoir sits at the heart of this Fergus County landscape, anchoring a network of drainages and small-scale water management features typical of the Montana plains in the late 1970s. The topography is dominated by the meandering course of the Sacagawea River, which carves through the central portion of the sheet. Further north, the terrain is defined by the winding path of Little Crooked Creek, while Antelope Creek cuts across the southern reaches. This provisional survey captures the area’s water resources just before the mid-1980s, including the smaller Harr Reservoir. The map reflects a sparsely populated ranching or grazing environment where named water bodies and reservoirs serve as the primary landmarks and vital infrastructure for the local land use of the era.
