SDIP has completed the final EIS/EIR and has entered into the permitting phase. Prior to obtaining permits to construct and operate the SDIP the US Fish and Wildlife Service (USFWS) and National Marine Fisheries Service (NMFS) must issue biological opinions under the federal Endangered Species Act (ESA). ESA consultation for the operation of the permanent operable gates proposed by the SDIP was included in the Operations Criteria and Plan (OCAP). OCAP covers the operations of the State Water Project and Central Valley Project, and both the USFWS and NMFS rendered Jeopardy Biological Opinions on OCAP. The NMFS Biological Opinion was issued in June 2009 and specifically directs DWR to halt implementation of the SDIP. NMFS indicates that consultation for the SDIP cannot be reinitiated until after three years of fish predation studies at the South Delta temporary barriers are completed. After all permits have been acquired DWR can proceed with construction. There currently is not a schedule for project completion.

Welcome to the South
Delta Improvements Program website.
The purpose of this website is to provide information about the South Delta Improvements Program (SDIP). The SDIP is a series of proposed actions to improve water quality and protect salmon in the southern part of the Sacramento-San Joaquin Delta while allowing the State Water Project to operate more effectively to meet California's existing and future water needs. The SDIP has a two-stage decision-making process: a) Stage 1 addresses the physical/structural improvements proposed in the SDIP. This includes new operable gates, dredging and agricultural diversion modifications. b) Stage 2 addresses the proposed operational component to increase water deliveries south of the Delta, and begins after the Stage 1 decision is made.
You will find a link for a complete
overview of the program in the right side bar.
There you will learn about the program
and the staged decision to determine the best project
for meeting the state's water supply needs while maintaining
our historical commitment to the environment.
Please browse our website to find all the information you need on SDIP, including SDIP Overview, Documents, Maps, Photos, Designs, and Related Links.
