85R26950 RMA-D By: Lucio III H.C.R. No. 135 CONCURRENT RESOLUTION WHEREAS, The United States and Mexico entered into a treaty regarding the utilization of waters of the Colorado and Tijuana Rivers and of the Rio Grande on February 3, 1944; and WHEREAS, Article 4 of the treaty allots to Mexico two-thirds of the flow into the main channel of the Rio Grande from the Upstream Mexican Tributaries, which consist of the Conchos, San Diego, San Rodrigo, Escondido, and Salado Rivers and Las Vacas Arroyo, with one-third allotted to the United States; and WHEREAS, Article 4(B)(c) of the treaty provides that the one-third flow from the Upstream Mexican Tributaries to the United States shall not be less than 350,000 acre-feet per year on an annual average basis over a five-year period; and WHEREAS, Flows from the Upstream Mexican Tributaries enter the Rio Grande below Fort Quitman and above or into the Amistad and Falcon Reservoirs; those flows not only benefit downstream water users in Texas but also provide needed instream flows for recreation and area ecosystems; and WHEREAS, In 2015, the International Boundary and Water Commission and Texas representatives arranged for the commission to accept deliveries from the Rio San Juan, a Mexican tributary below the Falcon Reservoir, which would be credited against delivery obligations from the Upstream Mexican Tributaries, to the extent that those waters could be diverted and utilized by Texas water users; and WHEREAS, By crediting deliveries from the Rio San Juan or other downstream Mexican tributaries, the delivery obligations for the Upstream Mexican Tributaries would be reduced by a three-to-one ratio, since with each acre-foot credited, the stretch of the Rio Grande between Fort Quitman and the Falcon Reservoir is deprived of a total of three acre-feet of needed instream flows; and WHEREAS, Crediting deliveries from the Rio San Juan or other downstream Mexican tributaries against delivery obligations of the Upstream Mexican Tributaries directly contravenes the provisions set forth in the 1944 U.S.-Mexico water treaty; now, therefore, be it RESOLVED, That the 85th Legislature of the State of Texas hereby urge the International Boundary and Water Commission to follow the express terms of the 1944 U.S.-Mexico water treaty in determining which flows are allowed to be credited against delivery obligations for the Upstream Mexican Tributaries; and, be it further RESOLVED, That the Texas Legislature hereby express its opposition to the International Boundary and Water Commission providing further credits to Mexico for water deliveries from the Rio San Juan or other downstream Mexican tributaries against Mexico's delivery obligations from the Upstream Mexican Tributaries; and, be it further RESOLVED, That the Texas secretary of state forward official copies of this resolution to the Texas governor, the Texas Water Development Board, the Texas Commission on Environmental Quality, and the International Boundary and Water Commission.
