Rio Grande waters dominate this San Luis Valley landscape, which is defined by an intricate network of irrigation infrastructure and drainage systems. The map details the complex hydraulic engineering required for high-altitude agriculture, featuring prominent arteries like the San Luis Valley Canal, Lower Centennial Ditch, and Costilla Canal. These waterways crisscross the valley floor, supporting the rural sections north of Alamosa. The settlement of Alamosa itself appears in the southeast corner, where the street grid begins to give way to recreational features like the Simpson Loop Trl. This documentation of the modern water system illustrates the persistent reliance on historic water rights and gravity-fed channels, including the Excelsior Ditch and Centennial Ditch, which remain central to the region's geographic identity and economic life.
