Long-Term Operation of the State Water Project in the Sacramento–San Joaquin Delta, Suisun Marsh, and Suisun Bay

Long-Term Operation of the State Water Project in the Sacramento–San Joaquin Delta, Suisun Marsh, and Suisun Bay

DWR is proposing an alternative decision-making approach to the collaborative approach described in the FEIR in section 2.3.3.2, Start of OMR Management, subsections of 2.3.3. Real-Time Adjustments, including Adult Delta Smelt Entrainment Protection Action and Larval and Juvenile Delta Smelt Protection Action, and section 2.3.22 Governance, subsection 2.3.22.4, Delta (2024 Incidental Take Permit for the Long-Term Operations of the California State Water Project Conditions of Approval [COAs] 8.5.1 and 8.6.1, which in turn would affect three of the Delta Smelt Actions [COAs 8.3.1, 8.3.2, 8.4.1]). The proposed modifications include the following: • The First Flush Action, Adult Delta Smelt Entrainment Protection Action (Turbidity Bridge) and Larval and Juvenile Longfin Smelt Protection Action will be added to the list of SWP management actions that are subject to assessment. o Assessments will propose operational adjustments within boundaries no more negative than -5,000 cfs OMR. o Assessments will include an evaluation of impacts to covered species by proposed operations, informed by available quantitative tools and real-time data, which may include entrainment and routing, modeling, distribution, and other real-time data, as appropriate. • Allow real-time assessment for Delta Smelt winter and spring entrainment protection actions. o DWR will provide an assessment framework that considers covered species impacts. o DWR will develop a science plan to improve understanding of Delta Smelt and salmonid movement and migration behaviors during the OMR flow period that will inform the real-time assessment framework of OMR flow management for Delta Smelt and Salmon and develop new operational conditions by 2029. No changes to SWP facilities or other operations are proposed.
