The U.S.-Mexico boundary is a political division and, although surveyed, mapped and patrolled, cannot completely determine the two nations' rights to the water resources along their common border. The flow of rivers and streams and the occurrence of groundwater are largely determined by nonpolitical, natural forces. As a result, the United States and Mexico must often negotiate the allocation and use of border water resources.
