Targhee National Forest dominates the northern landscape where Warm River and Robinson Creek converge. This 2013 survey illustrates the complex water management system of the Snake River Plain, featuring the Yellowstone Canal, Marysville Canal, and Farmers Own Canal as they divert water across the plains south of Hale Canyon. These irrigation works represent a critical layer of the region's agricultural development, supporting rural settlements like Grainville and Squirrel.
