3. Brock ReservoirReservoir

4. Yuma Desalting Plant

5. Colorado River System Augmentation Snowpack Augmentation (Cloud- seeding) Status: Pilot projects continuing in Colorado, Utah, and Wyoming Research & verification project in Wyoming Long-term, regional plan in development Upper Basin – Lower Basin cooperation

6. Basin States Wx Mod Program

7. Wind River Generator

8. System Augmentation Vegetation Management (Tamarisk removal) Status: Tamarisk Coalition Study completed Study suggests water salvage opportunity Planning for demonstration project in the Cibola area USGS Study reports similar data and results, different conclusion

9. Lower Colorado River Tamarisk Replacement Concept Colorado River Riparian Zone “Upland” Zone Water salvage potential is site dependent.

10. New Water Long-term Options Desalination Brackish Ocean Advanced Treatment Importation Water Reuse Active Conservation

11. Ocean & Brackish Desalination Imported Water Water Reuse

12. New Water Supplies Brackish Water Desalination: YDP IID Drainage - Salton Sea Binational Ocean Desalination: Rosarito Study Sonora Puerto Libertad Puerto Penasco

13. 13 YDP Potential YDP Operations MODE (to Cienega) To Mexico MODE (from Wellton-Mohawk) Colorado River Morelos Dam Other Yuma Area Brackish Water

14. Sonora Desal Concept ≈168 miles

15. New Water Supplies Colorado River Basin Study: USBR + Basin States collaboration Broad stakeholder involvement CAP is a funding partner Study seeks to identify and address “demand and supply imbalances in the Colorado River Basin” Supply and demands through 2060 Impact of climate change will be estimated and addressed

16. New Water Supplies Colorado River Basin Study Status: Supply analyses on-going 4 water supply scenarios Demand analyses on-going 4 demand scenarios Augmentation & Conservation approaches will be identified and evaluated in Fall - 2011 Augmentation approaches will leverage and improve on previous studies

17. How Long Does It Take Hoover Dam: 1902 - 1936 34 Years from First Plan to First Delivery 1922 Interstate Compact 20 Years from Concept to Institutional Agreement 1928 Boulder Canyon Act 6 Years from Agreement to Federal Law 1936 Operations
