About this map

Gunnison National Forest dominates the eastern landscape of this Gunnison County region, anchored by the massive high-altitude plateau of Flat Top. The western portion of the terrain transitions into a complex network of agricultural and hydrological engineering, where water management is central to the local economy. An Old Railroad Grade follows the contours of the valley floor, tracing a path alongside Ohio Creek, illustrating the historical transportation routes that once serviced this part of the Colorado interior.

Water rights and distribution are clearly marked through several named irrigation features, including the Teachout Ditch, Lone Pine Ditch, and May Bohm Ditch. These human-made channels, along with the Gunnison Highline Canal, reveal the intensive efforts to divert mountain runoff from sources like Antelope Creek and Willow Creek for valley use. Evidence of early industry is present at a solitary Mine in the northwest, while a Gaging Sta on Ohio Creek highlights the ongoing importance of monitoring the region's vital water flow.
