Welcome to the Temporary Barriers Project website.

The purpose of this website is to provide background and information on the purpose, goals and status of the Temporary Barriers Project (TBP).

The TBP prepares environmental documents, obtains regulatory permits, and administers the annual construction, operation, and monitoring of the Temporary Barriers.  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.

Please browse our website to find out about TBP Information, TB Operating Schedule, TBP Weekly Updates, Barriers Schedule, TB Monitoring Reports, TB Photos, Delta Overview, and Related Links & Documents.
