About this map

The city of Alamosa anchors this landscape in the San Luis Valley, where an extensive network of human-made waterways manages the high-desert environment. This 2010 survey highlights the complex irrigation system supporting local agriculture, featuring major channels like the Excelsior Ditch, Maddux Ditch, and Costilla Canal. These arteries pull from the Rio Grande and the Alamosa River, crisscrossing the terrain to sustain the region's ranching and farming operations.

South of the city, the San Luis Valley Regional Airport stands as a primary transportation hub, while the eastern edge of the map is defined by the elevation of Hansen Bluff. Water management remains the dominant theme throughout the quadrangle, evident in features like Adams Lake and the Waverly Drain Ditch. The map provides a clear record of the intersection between natural hydrology and the persistent engineering required to live and work in this corner of Colorado.
