2011 Map of Pipes Coulee

About this map

The Sacagawea River meanders across this Fergus County landscape, defining a network of drainage basins that include Little Crooked Creek and Antelope Creek. This 2011 survey captures a region managed through local water engineering, marked by several small impoundments such as the Little Crooked Rudolph Dam and Umstead Reservoir Dam. The topography is characterized by distinctive coulees—steep-walled drainage valleys—including Pipes Coulee, Schoneke Coulee, and Hay Coulee, which shape the movement of water toward the river system.
