Why is SDIP proposed?
The SDIP is proposed in response to three important water management needs: 1. The operations of the SWP and CVP export facilities in the south Delta can change flow patterns in the local channels. This can cause migrating San Joaquin River fall- /late fall-run Chinook salmon, a candidate for listing under the federal Endangered Species Act, to move into the south Delta, primarily through Old River where fish mortality increases due to predators and higher levels of exposure to export facilities and agricultural diversions. Keeping fall- and late fall-run Chinook salmon in the main channel of the San Joaquin River until they reach the central Delta may increase their survival.
