2011 Map of Fergus NE

About this map

Armells Creek and its tributary Dry Armells Creek define the drainage patterns of this Fergus County landscape, where small-scale water management infrastructure supported ranching operations in the early 21st century. The topographic data reveals a network of coulees, such as Murphy Coulee and Burnshed Coulee, that carve through the high plains toward larger watercourses. Localized water storage is a central feature of the area, evidenced by the Petranek Reservoir and its associated Petranek Reservoir Dam, along with other structures like the Petranek Dam and Satterfield Dam. These man-made improvements underscore the vital importance of water rights and management in central Montana, where creeks such as Cottonwood Creek and the South Fork Cottonwood Creek provide critical resources in a semi-arid environment. The map provides a clear record of these named landmarks and their relationship to the natural coulee systems.
