The 2-Gates Project proposes an alternative management strategy to achieve protection of the delta smelt (Hypomesus transpacificus). The Central Valley Project (CVP) and State Water Project

(SWP) operate under the OCAP and other water rights and water quality requirements (project background provided in Appendix A). These operations comply with the RPAs in the recent BOs for the OCAP from the U.S. Fish and Wildlife Service (FWS 2008) and National Marine Fisheries Service (NMFS 2009). The RPAs include actions to limit reverse flows in Old and Middle Rivers to reduce entrainment of fish at the CVP and SWP export facilities.

The Project seeks to provide equal or improved protection to delta smelt (reduced entrainment at the export pumps) with higher than the minimum allowed water exports described in the OCAP BORPAs while operating within the other water management requirement (D-1641). In particular, the Project is intended to demonstrate that operable barriers, strategically placed in the central Delta and managed in conjunction with some restrictions on OMR negative flows, can provide equal or greater protection for delta smelt than restrictions on OMR negative flows alone. The proposed 2-Gates Project is designed as a demonstration project to test this premise and to improve understanding of the key physical and biological processes needed to restore a sustainable ecosystem.

The 2-Gates Project proposes to install and operate temporary, removable gates in two channels in the central Delta at Old River and Connection Slough (Figure 1). The gates will be used to manipulate flows and key water quality components of delta smelt habitat in order to reduce entrainment of delta smelt at the export facilities.

2017 Flood System Status Report

This report is intended to assist flood management planners and engineers in characterizing facilities within the State Plan of Flood Control (SPFC) and to inform the 2017 Central Valley Flood Protection Plan Update (2017 CVFPP Update). The 2017 FSSR provides a concise repository of the status of SPFC Facilities as noted in related DWR evaluation and inspection efforts, along with the efforts of our local and federal partners. The 2012 CVFPP laid the foundation necessary for compliance with the Central Valley Flood Protection Act of 2008 and a new approach to flood management in the Central Valley.

As a supporting and informational document to the 2017 CVFPP Update, the 2017 FSSR includes information about inspecting and evaluating SPFC facilities. It also details and quantifies major components of existing flood risk within the Sacramento and San Joaquin river watersheds, and the factors that influence flood risk in relation to the various flood control structures within the SPFC. Additionally, the 2017 FSSR informs and details the current conditions of levees and channels within the SPFC, and includes finalized project information from DWR’s Levee Evaluations Program. Through updating the status of SPFC facilities, the State of California can continue to make informed decisions related to flood risk management.

This document is a collaborative effort by DWR, local, and federal partners, signifying a step forward in gaining deeper understanding of the flood system’s current status and condition in the Central Valley.
