22. Colorado River Basin Water Supply and Demand Study
Study Objective
Assess future water supply and demand imbalances over the next 50 years
Develop and evaluate opportunities for resolving imbalances
Study conducted by Reclamation and the Basin States, in collaboration with stakeholders throughout the Basin
Began in January 2010 and completed in December 2012
Provides a technical foundation for future activities; non-decisional document
Colorado River water supply
Serves over 40 million people
Provides irrigation water for over 5.5 million acres
Lifeblood for over 22 tribes
Significant source for Mexico
Major source of hydropower for the Southwest
7 Wildlife Refuges, 4 National Rec Areas, and 11 National Parks
Major drivers of change
Population growth (up to 70 million)
Drought and climate change
Evolving Ag and energy water needs
Evolving federal, state, and NGO roles 22

24. System Reliability – Multiple Resources
System reliability evaluated over the next 50 years for each scenario, with and without options and strategies
Use metrics and vulnerabilities to quantify impacts to Basin resources
Resource Categories
Water Deliveries
Electrical Power Resources
Water Quality
Flood Control
Recreational Resources
Ecological Resources

25. Options and Strategies Evaluation Process
Increase Supply
Decrease Demand
Broad assessment of options to address long-term reliability
Multiple criteria evaluation
Portfolio development and analysis
Common elements in portfolios that reduce vulnerability
Modify Operations
Governance & Implementation
Economic, Environmental, Social Attributes of Options
Portfolio Development and Analysis A B C D
Long-Term Reliability
Urban
Agriculture
Environment

26. Basin Study Findings
The system is significantly vulnerable due to future potential trajectories of climate change and growth Broad range of options can reduce resource vulnerability and improve the system’s resiliency to low and variable hydrologic conditions In the near term, all portfolios show that conservation, transfers, and reuse are cost-effective ways to reduce vulnerability In the longer term, more tradeoffs emerge to achieve an acceptable level of risk in terms of options, cost, resources, and other implications

27. Moving Forward Next Steps after the Study
Addressing future imbalances will require diligent planning and collaboration at all levels Next Steps process initiated in June 2013 Phase I underway and anticipated to be completed by Summer 2014
