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

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

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

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
