2020 Map of Cornwell Reservoir

About this map

Hunt Spring and Burke Spring dot this drainage basin in Valley County, where water resources define the remote landscape. The terrain is characterized by a series of coulees—deep, often dry streambeds or ravines—including Alkali Coulee, Wire Grass Coulee, and Mooney Coulee. These features suggest a history of seasonal runoff and a reliance on localized water sources in an arid ranching or grazing environment.
