About this map

The Rio Grande and the Alamosa River converge in a complex network of wetlands and man-made irrigation channels just east of Alamosa. This landscape is defined by its water management history, featuring an intricate system of laterals and ditches such as the Chicago Ditch, Maddux Ditch, and Seamans Ditch that support the surrounding agricultural valley. To the south and east, the Alamosa National Wildlife Refuge preserves the river bottomlands, while the prominent Hansen Bluff rises above the eastern plains.

Local infrastructure is anchored by the San Luis Valley Regional Airport/Bergman Field and the Alamosa Municipal Cem. The map documents the residential expansion of Alamosa East, where street names like Bonney Dr and Tinkham Ln reflect mid-to-late 20th-century development patterns. This survey provides a clear view of how high-altitude desert hydrology has been engineered to sustain both local aviation and regional ranching.
