2011 Map of Kachia Reservoir

About this map

Kachia Reservoir and the surrounding drainage of the Sacagawea River define this ranching landscape in Fergus County during the early 21st century. The terrain is characterized by a sophisticated system of water management, evidenced by numerous man-made structures including the North Roy Dam and a series of numbered projects such as Ed Styer Number 3 Dam, Ed Styer Number 4 Dam, and Ed Styer Number 5 Dam. These features suggest a landscape deeply tied to livestock and agricultural sustainability in a region where seasonal water flow is critical. The map also traces the winding paths of Little Crooked Creek and Antelope Creek, which feed into larger reservoirs like Harri Reservoir. A notable historical transit point is found at Cottonwood Crossing, marking a specific location where travelers or ranchers historically traversed the river system before the modern road network was fully established.
