Agricultural water management systems define this high-altitude landscape in Alamosa County, where the Costilla Canal and various irrigation channels like the Central Lateral and S Lateral support the local ranching and farming economy. The map reveals a strictly gridded survey system characteristic of the San Luis Valley, divided by numerous county roads including Co Rd 111 and S Co Rd 110. Small residential or farm clusters are indexed by specific local routes such as Copper Dr and Polk Ave. This 2019 survey documents the enduring reliance on gravity-fed water distribution in a region where historical water rights and infrastructure remain central to the settlement pattern and land use.
