1950 Map of Prospect Valley

USGS Topo · Published 1965

About this map

Prospect Valley in the mid-century is defined by its sophisticated irrigation network and its position along the Chicago Burlington and Quincy railroad. This 1950 survey reveals a high-plains agricultural landscape where water management is central to life, evidenced by the Low Line Canal, Henrylyn Canal, and numerous lateral ditches like the Prospect Lateral. These engineered waterways cut across the natural drainage of Lost Creek and Sand Creek, supporting local farmers and small stopping points on the rail line. Small settlements and family-named landmarks such as Johnson, Sheehan, Sloan, and Krauss are scattered across the valley, while the Prospect Valley School and the USBR Prospect Valley Sub Station serve as community anchors. The inclusion of Lord Reservoir further highlights the critical nature of water storage in this section of the Colorado plains near the Weld and Adams county line.
