Boundary Waters - Agreement between the United States of America and Mexico.

This Agreement, effected through the exchange of notes, concerns the construction of works by Mexico for the rediversion of water of the Rio Grande river. The Government of the United States does not object to such rediversion provided that construction of works and carrying out of such measures would not in any way alter the existing rights and obligations under the Convention of 1906 on the distribution of waters of the Rio Grande. Joint supervision of the construction of works shall take place by the Mexican and the United States Commissioners before the International Boundary and Water Commission.
