<P> Currently, water is exported from the Sacramento - San Joaquin Delta to the State Water Project and the Central Valley Project . The water flows through a maze of river channels and sloughs before entering the Clifton Court Forebay north of Tracy . From here, the Banks Pumping Plant pumps water into the California Aqueduct and the South Bay Aqueduct; the nearby C.W. Bill Jones Pumping Plant pumps water into the Delta - Mendota Canal . If not diverted, the water would flow into San Francisco Bay . The freshwater / saltwater gradient has moved inland because of the 5 to 7 million acre feet (6.2 to 8.6 km) of water being removed from the delta each year for delivery to the Central Valley and Southern California . </P> <P> The Water Fix proposal includes two categories of construction: the north tunnels and the main tunnels . The north tunnels are three separate tunnels, each about 14 miles long, which connect the three intake facilities to the Intermediate Forebay (IF). The main tunnels are intended to connect the Intermediate Forebay to the Clifton Court Forebay . These twin tunnels, depicted in the adjacent image, will be about 30 miles long . The main tunnels are also known as the twin tunnels, but are different from the Peripheral Canals proposed in 1982 . The Water Fix is intended to make conveyance of water for the State Water Project and Central Valley Project more reliable while relieving environmental pressure on the Delta area . </P> <P> The proposal details the planning and construction of the project . It provides that the Department of Water Resources enters a contract with the project manager for the Water Fix and a program director will coordinate with the department . Managing the project would be a board of directors known as the "Authority Board", which would receive and review monthly status updates on the construction of the Water Fix . The "Authority Board" has a "Program Advisory Group" to advise board members, made up of technical experts from the Department of Water Resources . The director of the Department of Water Resources would have final control of all aspects of the project . To control and monitor each of the facilities the proposal includes a Supervisory Control and Data Acquisition (SCADA) system at each location which can be controlled locally or remotely . The system would connect to the Delta Field Division Operations and Maintenance Center as well as to the Joint Operations Center in Sacramento . </P> <P> Though the Water Fix proposal aims to resolve some issues with the California water system, there are many it does not address . The plan does not consider the possibility that there could be less flow in the Sacramento River, nor does it address how to allocate water to fisheries found in the Delta, some of which are already struggling because of current water exports from the Delta . There are also no plans to deal with the extreme subsidence that is happening in the Delta . </P>

The bay delta conservation plan’s twin tunnels have been criticized as a new version of what
