The Alamosa city center and its eastern neighbor Alamosa East anchor this survey of the San Luis Valley, showing a landscape defined by an intricate network of irrigation and water management. The Rio Grande and the Alamosa River wind through the valley floor, accompanied by human-engineered systems like the Excelsior Ditch, Chicago Ditch, and Costilla Canal. These waterways underscore the region’s agricultural reliance on snowmelt and river diversion.
