Animas River (On-e-mas) (Río de las Ánimas, in Spanish) is a 126-mile-long (203 km) river in the western United States, a tributary of the San Juan River, part of the Colorado River System.
The Animas-La Plata Water Project was completed in 2015. The project pumps water over a low pass to fill a reservoir, Lake Nighthorse, in Ridges Basin to satisfy Southern Ute tribal water rights claims associated with the Colorado Ute Settlement Act amendments of 2000.
