About this map

N Fork Crazy Woman Cr and its sister branches carve a complex drainage system through the high plains of Johnson County. The landscape is defined by a dense network of topographic features including T A Hills and numerous named coulees such as George Hess Draw, O'Malley Draw, and Spring Draw. This 2021 topographic survey illustrates the ongoing importance of water management in the region, featuring infrastructure like the Steffensen Number 2 Reservoir and early irrigation projects like Devon Ditch Number 1 and Beaver Tooth Ditch.
