  4. Regional Hydrography Verde River

  5. Monterrey Leon Aguascalientes Guadalajara Mexico City

  6. Characteristics of the Project • 130m height (Lake Travis 85m) • Flooded Area 4,800 Ha (Lake Travis 7,800 Ha) • Volume 990 Mm3 (Lake Travis 1,400 Mm3) • Roller-Compacted Concrete • Water supply for 30 years • M.A. of Guadalajara • Leon • Los Altos

  7. Precipitation Distribution

  8. Population Benefited &Water deficit Depletion of Water Table • Leon ~ 3m/year • Aguascalientes ~ 1m/year Extraction below 400m *Guadalajara Metropolitan Area **Not included in the project

  12. Water Distribution Leon – Los Altos

  13. Chapala Lake

  14. Flooded Communities 365 480 185

  15. Flooded Communities

  16. Aguascalientes • Irrigation District #1 • 57 Mm3/year • State Deficit 325 Mm3/year • Depletion of Water Table • Subsidence • Seismic activity • Reduction in Aquifer Capacity • Obligation to treat water • Presence of heavy metals in drinking waters sources • Alternative Sources? • Alternative City

  17. Possible Conflict Points • Scarcity and Development • Upstream • Pollutant • Downstream • Historic use • Political power • Absolute volumes in water allocation • Political Boundaries do not match Social Boundaries • Political Force/Party • Duplicity of work • Plan ahead • Negotiate a treaty with your neighbor before someone else does!
