Seventy-seven Ranch and the isolated drainage systems of Sheridan County define this high-plains landscape as it appeared in the early 21st century. The terrain is marked by a complex network of intermittent watercourses, including the North Fork, Lotspeich Prong, and Randall Prong of Waddle Creek, which highlight the importance of water management in this arid ranching environment. This reliance on seasonal flow is anchored by the Fordyce Deer Creek Dam along the South Fork Deer Creek.
