"Colorado River The Colorado River is one of the principal rivers of the Southwestern United States and northern Mexico (the other being the Rio Grande). The river drains an expansive, arid watershed that encompasses parts of seven U.S. and two Mexican states. Starting in the central Rocky Mountains of Colorado, the river flows generally southwest across the Colorado Plateau and through the Grand Canyon before reaching Lake Mead on the Arizona–Nevada border, where it turns south toward the international border. After entering Mexico, the Colorado approaches the mostly dry Colorado River Delta at the tip of the Gulf of California"

On maps of Arizona, in the Altar Valley region, the United States-Mexico border changes direction to the northwest to end at the Colorado River at Yuma, Arizona. This change in border direction mostly follows a water divide change, separating drainage basins from each country; there are minor regional exceptions along the border to Yuma and the California border. Southern Arizona's desert waters flow north-northwest mostly ultimately ending at the Gila River which starts in extreme southwestern New Mexico and ends at Yuma, bordering California. Mexico's border drainage is into the Gran Desierto de Altar, with"
