1942 Map of Mile High Lakes

About this map

Agricultural development and water management define this High Plains landscape east of the Rockies, where a complex network of man-made waterways supports the region's ranching economy. The Barr Lake (Reservoir) dominates the western edge, feeding into an intricate system of gravity-fed irrigation channels including the Hudson Canal, East Burlington Canal, and the Denver-Hudson Canal. These engineering works transformed the naturally arid terrain around Third Creek and Grass Valley Creek into productive land for family operations like the Miliken Ranch, Patton Ranch, and Chapman Ranch.
