  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.
