The lands of the Navajo Nation are located within the four sacred mountains. Navajo lands are located in three states and multiple water basins and sub-basins. The major basins are the Upper and Lower Basins of the Colorado River and the Rio Grande Basin. Water rights are typically determined by basin. Information on the status of Navajo water rights determinations can be found by clicking on the Basin tabs at the top of the page or on the area of interest on the map above.
