2020 Map of Kachia Reservoir

About this map

The Sacagawea River winds across this Fergus County landscape, defining a terrain shaped by the intermittent water of the high plains. In this 2020 topographic record, water management for ranching or local use is evident through the placement of Harri Reservoir and Kachia Reservoir, which capture runoff in an area where smaller tributaries like Little Crooked Creek and Antelope Creek are seasonal. The historical movement through this territory is traced by the Wilder Trail, which skirts the northern section of the map. This survey provides a modern snapshot of the Public Land Survey System divisions in Montana, showing the established grid of T19N and T20N within the R24E and R25E ranges, a structure that has organized this open country for generations.
