Well over 50 percent of the San Juan River watershed are Native American lands, the largest being the Navajo Nation, which covers portions of New Mexico, Arizona and Utah, in addition to the Jicarilla Apache Nation in New Mexico and the Ute Mountain and Southern Ute Indian Reservations in southwest Colorado. Federal agencies, principally the Bureau of Land Management, Forest Service and National Park Service, administer about 25 percent of the watershed. About 13 percent are privately owned (non-Indian) lands, and 3 percent belong to state and local governments.
