The San Francisco Bay and Sacramento-San Joaquin Delta form one of the largest estuaries in the United States. The “Bay-Delta” system provides water to more than 25 million California residents and vast farmlands, as well as key habitat for birds, fish, and other wildlife. To help ensure the health of this crucial estuary, the U.S. Geological Survey, in close cooperation with partner agencies and organizations, is providing science essential to addressing societal issues associated with water quantity and quality, sediment transportation, environmental contamination, animal health and status, habitat restoration, hazards, ground subsidence, and climate change.

San Francisco Bay enters most of our lives as an obstacle to pass over as quickly as traffic-choked bridges allow. Although this beats earlier attitudes—when we saw the Bay mainly as a dumping ground, a dam site, or a pit to fill in and pave over—we remain largely oblivious to one of the most remarkable wild resources in urban North America. Beneath our wheels lies a world of interesting and outlandish life, with much that puzzles even the scientists who regularly plumb its depths.

This report proposes a reconciliation approach for addressing 160 years of accumulated problems and for managing the Delta’s ecosystem in the future. Reconciliation ecology seeks to improve conditions for native species while recognizing that most ecosystems have been altered irrevocably by human use and will continue to be used to support human goals. Improving ecosystem conditions for native species must, therefore, happen in a context of continuing use of land and water by humans and continuing physical and biological change.

The report focuses on the State Water Board’s responsibility to enforce water rights and to prevent unauthorized diversions of water in the state of California.
Pursuant to the Water Code, the State Water Board is responsible for enforcing the terms and conditions of water right permits, licenses, and registrations, as well as investigating diversions of water. As addressed in the Strategic Workplan for Activities in the San Francisco Bay / Sacramento-San Joaquin Delta Estuary, the State Water Board is directed to investigate illegal diversions and violations of permit and license conditions and take action when violations are occurring in the Bay-Delta Watershed.
The report discusses how the State Water Board began an investigation of illegal diversions of water, focusing on the Delta. For instance, the State Water Board has investigated two islands in the Delta to establish whether the landowners possessed any water rights. Most did, though some individuals were subject to more review, the majority of which concerned validating riparian claims for severed parcels.
The report notes that the State Water Board has also investigated diverters within an area of the southern Delta and resolved all cases resulting from that investigation. The report also discusses how the State Water Board has begun an investigation of water diverters, statewide, who have failed to file required reports, which include the annual reports for permit and license holders, and the supplemental statements.
Finally, the report suggests a new approach of looking at districts in the Delta who serve water to individuals, in addition to looking at compliance issues related to individual diverters.
