Navajo River

Navajo River (Jicarilla Apache: Lóolahó) is a 54-mile-long (87 km) tributary of the San Juan River. It flows from a source in the South San Juan Wilderness of Conejos County, Colorado southwest past Chromo, Colorado. The river dips into New Mexico, passing just north of Dulce before heading northwest to a confluence with the San Juan in Archuleta County, Colorado. A large portion of its water is diverted across the Continental Divide to the Rio Grande basin as part of the San Juan–Chama Project.
