The South Platte River valley defines the economic and geographic heart of this mid-century landscape, acting as a corridor for both water and transport through Northeastern Colorado. An intricate system of irrigation, including the Pawnee Ditch, Lowline Ditch, and Sand Hill Ditch, draws from the river to support agriculture across Jones Flat and the surrounding plains. These water rights were vital to the growth of hubs like Sterling, Fort Morgan, and Brush, which served as critical shipping points along the Union Pacific and Chicago Burlington and Quincy railroads.
