  8. 8. Convention of 1906• Distribution between Mexico and the U.S. of the waters originating in the Upper Rio Grande watershed.• U.S. to deliver 60,000 acre-feet per United States American year to Mexico at the headworks of Canal the Acequia Madre Canal Mexico• Proportional reduction in deliveries in case of extraordinary drought American Dam American Dam• Project water stored in Elephant Butte and Caballo Dams – New Mexico Excellence through teamwork.
  9. 9. Convention of 19063 Primary Entities served with Project Water from Elephant Butte and Caballo reservoirs • Elephant Butte Irrigation District • El Paso County Water Mexico’s Deliveries Improvement District No. 1 US Deliveries • MexicoPoor contingency planning in winter of 2011 led to a delivery timing conflict International Dam in 2012. Excellence through teamwork.
  10. 10. • US Irrigation Districts Historical Starts of drought management strategy was to defer Irrigation Season deliveries until Mid-May or early June.• Officially informed Mexico of their plan on February 15, 2012.• Mexico did not have well infrastructure in place to wait until Mid-May• Compromise – EP#1 agreed to come on-line with Mexico on April 5th.
  11. 11. Lesson’s Learned from 2012• Initiate early contingency planning with all three irrigation entities (Fall of 2012)• Need better understanding of how surface water in channel interacts with aquifer.• Need better understanding of how groundwater pumping impacts channel conveyance efficiencies.• Federal study - (USIBWC/Reclamation) with input from 3 irrigation entities to analyze surface/groundwater interactions of system and propose operational strategies to better manage precious resource.
  12. 12. 1944 Water Treaty – Rio Grande• Mexico delivers water to the U.S., Ft. Quitman to Gulf Conchos• U.S. receives 1/3 of the waters River arriving in the Rio Grande from 6 Mexican tributaries Rio Grande• Minimum annual average of 350 kaf in cycles of 5 yrs• Treaty authorized construction of up to three storage dams on Rio Grande; only 2 were built Excellence through teamwork.

  15. 15. RiverWare Modeling Objective: Develop comprehensive RioGrande basin model to support treatycriteria. RiverWare is a very flexible toolto support daily operations, mid-termforecasting, and long-range planning. USIBWC hired RiverWare subject matter expert. • Presently developing reservoir flood operation models. • Develop water accounting models in 2012. Combine model development with Mexico’s RiverWare models (in development) for comprehensive watershed model
