The Clarks Fork Yellowstone River carves through the landscape of northwestern Wyoming, defining the hydrology of this arid region. The high desert terrain of Badger Basin is dominated by an intricate network of early irrigation systems, including the Interstate Ditch, Doctor Ditch, and Clark Ditch. These human-engineered channels reveal the historical effort to transform the sagebrush flats into productive land, a pattern visible in the series of ditches like Simpson Ditch and Sirrine Ditch that traverse the basin floor.
