The Little Navajo River is a tributary of the Navajo River in Archuleta County, Colorado. It joins the Navajo River at Chromo, Colorado. A large portion of its water is diverted, at the Little Oso Diversion Dam, across the Continental Divide to the Rio Grande basin as part of the San Juan–Chama Project.[1]
