Purpose

The Delta Stewardship Council’s Delta Science Program is sponsoring a workshop to inform stakeholders and independent science panel members about the Sacramento Water Allocation Model (SacWAM).

 

SacWAM is a hydrology/system operations model developed by the Stockholm Environment Institute (SEI) and State Water Resources Control Board (State Water Board) to assess potential revisions to instream flow and other requirements in the 2006 Water Quality Control Plan for the San Francisco Bay/Sacramento-San Joaquin Delta Estuary (2006 Bay-Delta Plan). SacWAM was developed using the Water Evaluation And Planning (WEAP) system, and is intended to be user-friendly and to easily accept various scenarios.

 

The Delta Science Program is conducting an independent peer review of SacWAM to assure transparency and confirm the robustness of SacWAM for applications related to updates of the Bay-Delta Plan, and as part of the Delta Science Program’s mission to provide the best possible unbiased scientific information to inform water and environmental decision-making in the Bay-Delta system.

 

There will be a general stakeholder hands-on training of the SacWAM model, and a private hands-on training for the independent science panel; both sessions will include the modeling software creators, SEI.  Those sessions will be followed by a one-day public workshop in Sacramento, CA. The workshop will consist of presentations by the State Water Board and SEI, followed by a presentation of preliminary findings by the panel. There is no charge for attending the workshop.

 

Charge to the Independent Review Panel

The charge to the panel provides the orientation and focus, materials to be reviewed and specific questions for the panel to start the review process. It provides the direction, context and timeline for the review.

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)
