In November 2011, the Colorado River Basin Water Supply & Demand Study began its fourth and final phase: Development of Opportunities to Balance Supply and Demand. From November 2011 through February 2012 public input was sought for ideas on a broad range of potential options to help resolve projected water supply and demand imbalances in the Basin. During this period, 160 ideas were submitted, representing a broad range of possibilities.

Information on the preliminary assessment of potential future water supply and demand imbalances, and the approach for organizing and evaluating options was published in Phase 4: Development and Evaluation of Opportunities for Balancing Water Supply and Demand - Request for Ideas.

Technical Report F - Development of Options and Strategies describes the submitted options, the process for characterization of these options, the results of characterization, and the development of exploratory portfolios from the characterization results to address future supply and demand imbalances.
