Reservoir Levels Weather Hydrology

Elephant Butte Reservoir, located in southern New Mexico, was created in 1916 by the damming of the Rio Grande. The reservoir has a storage capacity of 2.2 million acre-feet and is the largest reservoir in the state. The hydrology of the reservoir is primarily fed by snow melt and surface flow from the Rio Grande, as well as irrigation runoff from nearby agricultural fields. The reservoir provides water for agricultural and recreational uses, including boating, fishing, and camping. The snowpack providers for the reservoir include the San Juan and Sangre de Cristo mountain ranges, while the surface flow is mainly provided by the Rio Grande and its tributaries. The reservoir plays a vital role in supplying water to the surrounding areas, as well as the downstream agricultural lands and cities in Texas and Mexico.
