Summary

The President may build, fix, complete, protect, and run projects that a treaty with Mexico allows. He can also hand over running and upkeep to federal agencies or to state or local governments under rules he sets. He may do surveys and do work to build and keep a sewage interceptor that catches Tijuana sewage from selected canyon areas. Money spent on the Rio Grande bank protection project must follow the terms in the Act of April 25, 1945 (59 Stat. 89). The Anzalduas diversion dam cannot be used for U.S. irrigation or water supply unless the water users agree to repay the U.S. government for the dam parts assigned to those uses by the Secretary of State. The Secretary of State, through the U.S. Commissioner of the International Boundary and Water Commission, may make improvements to the Rio Grande Canalization Project (Act of August 29, 1935 (49 Stat. 961)) to help meet the Convention for Equitable Distribution of the Waters of the Rio Grande, May 21, 1906, including work to stabilize the river between the Percha Diversion Dam in New Mexico and the American Diversion Dam in El Paso.
