Sharing the Colorado River and the Rio Grande: Cooperation and Conflict with Mexico
Sharing the Colorado River and the Rio Grande: Cooperation and Conflict with Mexico December 12, 2018 Congressional Research Service https://crsreports.congress.gov R45430 {222A0E69-13A2-4985-84AE-73CC3DFF4D02}-R-065134085251065165027250227152136081055238021128244192097047169070027044111226189083158176100054014174027138098149076081229242065001223143228213208120077243222253018219014073197030033204036098221153115024066109133181160249027233236220178084 SUMMARY R45430 Sharing the Colorado River and the December 12, 2018 Rio Grande: Cooperation and Conflict with Nicole T. Carter Specialist in Natural Mexico Resources Policy The United States and Mexico share the waters of the Colorado River and the Rio Grande. A bilateral water treaty from 1944 (the 1944 Water Treaty) and other binational agreements guide Stephen P. Mulligan how the two governments share the flows of these rivers. The binational International Boundary Legislative Attorney and Water Commission (IBWC) administers these agreements. Since 1944, the IBWC has been the principal venue for addressing river-related disputes between the United States and Mexico. The 1944 Water Treaty authorizes the IBWC to develop rules and to issue proposed decisions, Charles V. Stern called minutes, regarding matters related to the treaty’s execution and interpretation. Specialist in Natural Resources Policy Water Delivery Requirements Established in Binational Agreements. The United States’ and Mexico’s water-delivery obligations derive from multiple treaty sources and vary depending on the body of water. Under the 1944 Water Treaty, the United States is required to provide Mexico with 1.5 million acre-feet (AF) of Colorado River water annually. The 1944 Water Treaty also addresses the nations’ respective rights to waters of the Rio Grande downstream of Fort Quitman, TX. It requires Mexico to deliver to the United States an annual minimum of 350,000 AF of water, measured in five-year cycles (i.e., 1.75 million AF over five years). -

This paper focuses its attention in the treaty obligations of water delivery from Mexico to the US in the Rio Grande/Bravo basin. For this basin, the treaty specifies a primary division of six tributaries originating in Mexico as one-third to the U.S. and two-thirds to Mexico. The third shall not be less than 431.721 million m3/year as an average over cycles of 5 consecutive years. Two international dams, Amistad and Falcon, are used to store and manage the water for both countries and each country has its own storage account in each reservoir. The treaty cycles can expire in less than five years if the account of U.S. storage in both dams is filled with water. Before the signature of the treaty, an analysis of the six tributaries outflow was done in order to evaluate the treaty obligations. -

Falcon Dam Releases to Increase on September 22; Diversions Into U.S
International Boundary and Water Commission United States Section For immediate release September 21, 2010 FALCON DAM RELEASES TO INCREASE ON SEPTEMBER 22; DIVERSIONS INTO U.S. INTERIOR FLOODWAY POSSIBLE The International Boundary and Water Commission, United States and Mexico, will increase releases from Falcon Dam, located at Falcon Heights, Texas-Nueva Ciudad Guerrero, Tamaulipas, from 8800 cubic feet per second (250 cubic meters per second) to 11,500 cubic feet per second (325 cubic meters per second) on the morning of September 22. The reservoir has continued to rise due to precipitation in the Rio Grande basin, requiring increased releases so as to maintain Falcon Reservoir at a safe level during the hurricane season. Nonetheless, releases remain well below peak releases of 60,000 cubic feet per second (1700 cubic meters per second) that occurred in July. Coupled with inflows from Mexican tributaries downstream from Falcon Dam – the Alamo River, which flows into the Rio Grande near Ciudad Mier, Tamaulipas, and the San Juan River, which flows into the Rio Grande near Rio Grande City, Texas-Ciudad Camargo, Tamaulipas, Rio Grande flow may reach a level requiring diversion of floodwaters into the U.S. interior floodway system in Hidalgo, Cameron, and Willacy Counties later this week. Based on information currently available, any diversions into the U.S. interior floodway would likely be minimal. The interior floodway system includes the Banker Floodway, Main Floodway, North Floodway, and Arroyo Colorado. Diversion of water into the U.S. and Mexican interior floodways in conformance with longstanding international agreements allows the Commission to limit Rio Grande flood conditions at Brownsville, Texas-Matamoros, Tamaulipas. -

Beyond the Rio Grande Water Debt
ISSUE BRIEF 12.08.20 Beyond the Rio Grande Water Debt Stephen P. Mumme, Ph.D., Nonresident Scholar, Center for the United States and Mexico The Rio Grande water war1 is over, at least Mexico’s capacity to meet the treaty’s for now. A summer’s worth of rancor, requirements. There is clearly a need to recrimination, violent protests, and one rethink at least some of the elements that tragic death ended abruptly on October 21, factor into the fulfillment of Mexico’s Rio three days before payment in full was due, Grande treaty obligations. when Mexico agreed to transfer water stored Ironically, the pertinent provisions of the in Rio Grande dams to the United States. 1944 water treaty, officially titled “Utilization Mexico’s last-minute decision to of Waters of the Colorado and Tijuana Rivers meet its 1944 water treaty2 obligation and of the Rio Grande,” were thought, at was greeted with both sighs of relief and the time, to be exceptionally flexible and annoyance in Texas where irrigation demand to Mexico’s advantage in meeting its treaty peaked July through September, diminishing deal (Enriquez Coyro 1976, 1174).

In Chihuahua, riled feet of water annually to the United States, farmers seized control of La Boquilla Dam a figure that is calculated as an average in the upper Rio Conchos in August to avert over a water delivery cycle of five years, a depletion of that reservoir to fulfill Mexico’s sum obligation of 1,750,000 acre-feet in treaty obligation, and a protest erupted each cycle. -
Commission Begins Releasing Rio Grande Floodwaters from Falcon Dam
International Boundary and Water Commission United States Section For immediate release 4:00 p.m. CDT, July 7, 2010 COMMISSION BEGINS RELEASING RIO GRANDE FLOODWATERS FROM FALCON DAM Due to upstream flood conditions and rising reservoir levels, the International Boundary and Water Commission, United States and Mexico, will initiate release of floodwaters from Falcon Dam, located at Falcon Heights, Texas-Nueva Ciudad Guerrero, Tamaulipas late in the afternoon of July 7. Water will be released into the Rio Grande at the rate of 15,000 cubic feet per second (425 cubic meters per second). This water will flow downstream into the Lower Rio Grande Valley where the Commission has a system of flood control levees, diversion dams, and floodways. Releases at this rate are well within the capacity of the United States flood control system. Residents in the Rio Grande Basin should continue to monitor National Weather Service warnings and forecasts for any updated information about flood conditions. The International Boundary and Water Commission expects to begin diverting floodwaters at Anzalduas Diversion Dam in Hidalgo County, Texas into the U.S. interior floodway during the night of July 7. These flows originated in the San Juan River, a Mexican tributary affected by heavy precipitation from Hurricane Alex and the spill of floodwaters from Marte R. Gomez Dam in Mexico. The initial volumes to be diverted into the U.S. interior floodway are expected to be low but will increase as flows from Falcon Dam arrive in the region on July 8. Diversions into Mexico’s interior floodway at Retamal Dam are also expected. -
