SUMMARY OF THE SOLICITATION

The Delta Stewardship Council is requesting qualifications from consultants to undertake a synthesis and scoping effort, including demonstration of applicable models related to the effects of island flooding, such as from levee breaks or tidal marsh restoration, on salinity and tides throughout the Sacramento-San Joaquin Delta using existing data and modeling capabilities. Such an analysis should provide a common and transparent basis for a range of Delta management decisions and agency needs such as:

  • State Water Project and Central Valley Project planning, operations, and regulation
  • Water Quality Control Plans, permits, and other water quality regulations
  • Risk assessment and responses for Delta levee failures
  • Delta levee investment policies and decisions
  • Emergency planning
  • Installation and operation of barriers for drought, water quality, and fish movement
  • Delta-wide water quality impacts of local habitat restoration activities
  • Adaptive management of habitat restoration projects and water supplies

 

Most current modeling efforts are focused on urgent project-specific management and regulatory needs. These modeling efforts could, in aggregate, contribute to a broader, system-wide understanding for management of Delta water quality and hydrodynamics.

This study should consider salinity, tidal dynamics, and flow effects for a variety of locations and water year types, relying on existing data and modeling capabilities to obtain a system-wide understanding and should at a minimum:

  1. Identify islands that are essential for continued attainment of the Bay-Delta Water Quality Control Plan objectives for salinity and flows and identify how results and model outputs could be made available for additional analysis (such as transport of additional water quality constituents).
  2. Identify applicable models capable of addressing the proposed Bay-Delta water quality control plan objectives and scope the level of effort required to obtain system-wide understanding of Delta water quality and hydrodynamics. Scoping, and potentially initial model runs, would include applying up to ten levee breach scenarios in Suisun Marsh and the western Delta in two water-year types (wet and blow normal).

Coequal goals

The Delta Stewardship Council was created in legislation to achieve the state mandated coequal goals for the Delta. "'Coequal goals' means the two goals of providing a more reliable water supply for California and protecting, restoring, and enhancing the Delta ecosystem. The coequal goals shall be achieved in a manner that protects and enhances the unique cultural, recreational, natural resource, and agricultural values of the Delta as an evolving place." (CA Water Code §85054)
