1984 Map of Threemile Creek Reservoir

About this map

The Belle Fourche River winds through this section of Campbell County, serving as the primary drainage for a network of intermittent streams and managed water resources. In the mid-1980s, the landscape was defined by its water management systems, including the Threemile Creek Reservoir and the Lower Threemile Reservoir. These features, along with Little Wild Horse Reservoir, indicate the importance of livestock watering and water retention in this high-plains environment. The map provides a look at the intricate topography surrounding Threemile Creek and Horse Creek, illustrating the natural contours and the sparsely populated ranching territory characteristic of north-central Wyoming. Small unimproved roads and trails connect these remote water points, reflecting the utilitarian infrastructure required for land management and cattle operations during this era.
