Surface Storage Investigations

Common Assumptions Teams
The Common Assumptions effort has established a number of teams to address different areas required to develop consistency among the individual storage projects. Attaining consistency in modeling assumptions and analytical approach will allow the surface storage projects’ performance, costs, and benefits to be compared on an equal basis. The Common Assumptions process also makes more efficient use of limited technical resources. The Common Assumptions teams provide:

  • Coordination to facilitate the resolution of study issues
  • Coordination with other ongoing activities such as the California Water Plan Update and Authority’s Year 4 Water Use Efficiency Evaluation
  • Development of technical tools and coordination of their use among the surface storage investigation study teams
  • Briefings to the Bay-Delta Public Advisory Committee’s Water Supply Subcommittee and its technical representatives

The Core Team comprises management representatives from DWR, U.S. Bureau of Reclamation, and the Authority. This team provides overall direction to the Common Assumptions process.

The Technical Coordination Team comprises technical staff from DWR, U.S. Bureau of Reclamation, and consultants. This team works on the refinement and development of common model packages for the existing and future no-action conditions. This team focuses on the following areas:

  • Consistent application of operations models
  • Development of common systems operations reporting metrics
  • Consistency in use of models and validation of consistency of modeling results
  • Development of cumulative impact analysis

The Economics and Cost Estimation Team comprises economists from DWR, U.S. Bureau of Reclamation, and consultants. This team works on the refinement and development of common economics models and cost estimation methodology.

The Characterization Team comprises technical staff from DWR, U.S. Bureau of Reclamation, and consultants. This team works on characterization and quantification of water transfers, conservation, recycling, conjunctive use, and other local supply projects.

The Project Management Teams comprise storage project managers from DWR and U.S. Bureau of Reclamation. These teams will apply common tools, methodology, and assumptions to analyses of their individual storage projects.
