COLORADO RIVERJOINT COOPERATIVE PROCESS
U.S.-MEXICO
ARIZONA-MEXICO COMMISSIONWATER COMMITTEE
C.W. “Bill” Ruth, U.S. CommissionerInternational Boundary and Water Commission,
United States and Mexico, June 5, 2009
IBWC MISSION
The International Boundary and Water Commission, United States and Mexico, is responsible for applying the boundary and water treaties between the two countries and settling differences that arise in their application.
1944 WATER TREATY– COLORADO RIVER
U.S. to deliver to Mexico a volume of 1.5 million acre-feet per year
Mexico diverts water at Morelos Dam
When there are surplus waters, U.S. to deliver to Mexico a total volume of up to 1.7 million acre-feet per year
In extraordinary drought, Mexico reduced in proportion to U.S.
Morelos Dam
COLORADO RIVER JOINT STATEMENT
Joint Statement issued Aug. 13, 2007 by DOI and Mexico’s Ambassador
IBWC should be utilized to expedite discussions on Colorado River cooperation on the following issues: continued needs of both nations for water for urban, agricultural
and environmental purposes, the study of the hydrological system and potential impacts of climate change, including the effects of the ongoing historic Colorado River drought
environmental priorities, including Colorado River Delta habitat protection and enhancement (implementation of Min. 306)
COLORADO RIVER JOINT STATEMENT
Joint Statement issues (continued): opportunities for water conservation, storage, and supply
augmentation such as seawater desalination and reuse, strategies aimed to ease variations in the Colorado River system
potential opportunities for more efficient Colorado River water deliveries to Mexico
COLORADO RIVER JOINT COOPERATIVE PROCESS
IBWC established a Binational Core Group to consider cooperative efforts
U.S. Core Group is comprised of: USIBWC Bureau of Reclamation California Nevada Arizona Upper Basin States Non-Governmental Organizations
COLORADO RIVER JOINT COOPERATIVE PROCESS
Mexico’s Core Group is comprised of: Mexican Section, IBWC National Water Commission (Conagua) Secretariat of Environment and Natural Resources Baja California Sonora Embassy of Mexico/Ministry of Foreign Relations Non-Governmental Organizations
COLORADO RIVER JOINT COOPERATIVE PROCESS Each country has established its objectives for
the cooperative process Objectives relate to:
Addressing current and future urban, agricultural, and environmental water needs
Management procedures for shortage conditions Efficiency improvements Water augmentation and storage options Environment Climate change, salinity, water exchanges, water
system operations, etc.
COLORADO RIVER JOINT COOPERATIVE PROCESS U.S. Priorities:
Desalination Wetlands protection Water delivery to Tijuana via the Otay connection Shortage management
Mexican Priorities: Irrigation district improvements Desalination of ocean water Sediment removal from the Wellton-
Mohawk Drain Hydraulic modeling related to the
Colorado River Delta Water delivery to Tijuana through the Otay connection
Wellton-Mohawk (l), Colorado River channel (r)
COLORADO RIVERJOINT COOPERATIVE PROCESS Core Group has established four Work Groups,
with broad participation from U.S. and Mexican stakeholders: New Water Sources – particular interest in
binational desalination Conservation – especially irrigation conservation
projects System Operations – seeking efficiencies in how
the system operates Environment – preserve and restore the ecosystem
of the limitrophe and Delta Each Work Group to meet approx. once/month Core Group to meet quarterly
COLORADO RIVERJOINT COOPERATIVE PROCESS
Binational Field Trip Held January 2009 Visited sites in the U.S. and Mexico
in the Lower Colorado River Desalination – Core Group has
authorized establishment of a Binational Technical Committee to study a proposed binational desalination plant at Rosarito
Limitrophe Reach – Environment Work Group is developing a map of priorities for conservation of the limitrophe and Delta
Cienega de Santa Clara – Environment Work Group has developed a proposed monitoring program for this wetland
Cienega de Santa Clara
U.S.-MEXICO JOINT DECLARATION 2009
Joint Declaration of DOI Secretary and Mexican Ambassador Sarukhan (Jan. 15, 2009)
Notes that recent periods of historic drought in the Colorado River Basin and growing recognition of the potential adverse impacts of climate change have stimulated efforts to identify cooperative and innovative approaches to ensure that the Colorado River allotment of each nation will continue to meet the needs of both nations
Applauds the efforts of IBWC to help identify cooperative and innovative measures that both countries could implement
Both governments support efforts to identify opportunities for water conservation, storage, supply augmentation, and environmental protection
CURRENT STATUS
Work Groups are analyzing projects that have been presented, the interrelationship of projects, and their environmental impact
U.S. Basin States presented to Mexico a discussion document concerning concepts for joint cooperative actions
IBWC is conducting talks about the discussion document
Core Group and Work Group meetings continue; meetings held June 2-3, 2009
