South Delta Improvements Program (SDIP): The SDIP is a series of proposed actions that 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 the new operable gates, dredging and agricultural 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.

Temporary Barriers Project (TBP): The TBP prepares environmental documents, obtains regulatory permits, and administers the annual construction, operation, and monitoring of the Temporary Barriers Project.  The purpose of the project is: to protect San Joaquin salmon migrating through the Delta and provide an adequate agricultural water supply in terms of quantity, quality, and channel water levels to meet the reasonable and beneficial needs of water users in the south Delta area.  The TBP also takes actions to protect agricultural diversions that do not benefit from the operations of the barriers, from the adverse effects of the barriers.

Proposition 84: In Chapter 2, Section 75029, the sum of $130 million shall be available to the department for grants to implement Delta water quality improvement projects that protect drinking water supplies. Eligible projects are: a) Projects that reduce or eliminate discharges of salt, dissolved organic carbon, pesticides, pathogens and other pollutants to the San Joaquin River; b) Projects that reduce or eliminate discharges of bromide, dissolved organic carbon, salt, pesticides and pathogens from discharges to the Sacramento River; c) Projects at Franks Tract and other locations in the Delta that will reduce salinity or other pollutants at agricultural and drinking water intakes; and d) Projects identified in the June 2005 Delta Region Drinking Water Quality Management Plan, with a priority for design and construction of the relocation of drinking water intake facilities for in-delta water users.

Recirculation: A federal project feasibility study for recirculating water from the Delta-Mendota Canal was authorized under Title 1, Section 103 of the CALFED Bay-Delta Authorization Act, Public Law 108-361 (PL 108-361). The project, if feasible, would implement a plan to recirculate water via the DMC through one or more flow paths to the San Joaquin River upstream of Vernalis. The objectives of the project would be to utilize excess capacity in the DMC to provide flow, reduce salinity concentrations in the San Joaquin River, and reduce reliance on New Melones Reservoir water supplies to meet water quality and fishery flow requirements.  The proposed DMC Recirculation Project will provide greater flexibility in meeting the existing water quality and flow standards and reduce demand on New Melones Reservoir water supplies.
 
DWR will serve as the CEQA State Lead Agency to prepare an Environmental Impact Report (EIR) and Reclamation will serve as the NEPA Federal Lead agency for the proposed Project.  A draft EIS/EIR pursuant to the NEPA and CEQA is expected to be available for review in 2008.
