Bay-Delta Activities Update - Aug. 25, 2011

- 2. Historic view of the Delta Present day activities ◦ Inter-relation of Bay-Delta process ◦ Bay Delta Conveyance Plan ◦ Delta Stewardship Council – Delta Plan Next steps 2
- 3. In 1930s, first State Water Plan envisioned exporting water from Delta By 1940s, federal Central Valley Project began exporting water By 1960s, California voters authorized construction of State Water Project; SWP began delivery of water in 1970s In 1982, referendum to complete Peripheral Canal – to convey SWP around the Delta – was rejected 3
- 4. CVP & SWP exports, along with other stressors, placed pressure on Delta that led to decline of important Delta fish species ◦ Winter-run Chinook salmon listed as an endangered species in 1989 ◦ Delta smelt listed as a threatened species in 1993 In 1994, CVP Improvement Act dedicated a portion of the federal water supply to the environment In June 1994, state and federal officials signed Framework Agreement to set principles to coordinate development of water quality standards to protect estuary, operations of SWP and CVP, and a long-term solution for the Delta; Bay-Delta Accord signed in December 1994 delineating management responsibilities 4
- 5. Bay-Delta Accord gave rise to CALFED Bay-Delta Program, a comprehensive water management and ecosystem restoration program ◦ CALFED brought together 25 state and federal agencies to coordinate and implement the actions set forth in the CALFED Record of Decision, signed in 2000 ◦ CALFED promised a balanced 30-year approach ◦ CALFED also promised emphasis on funding and guiding sound scientific research of the Delta and its many issues 5
- 6. Several significant legal challenges in process affect CALFED and the Delta In December 2007, per the ROD, an evaluation of the preferred alternative – through-Delta Conveyance – was completed ◦ Concluded through-Delta conveyance as the sole method of moving water to export system was not meeting the CALFED objectives ◦ CALFED agencies agreed that alternative conveyance mechanisms should be explored 6
- 7. Efforts to establish the Delta Vision process and a Bay-Delta Conservation Plan are based on work done through CALFED ◦ Delta Vision created by Executive Order of then-Governor Arnold Schwarzenegger on September 17, 2006 ◦ Bay Delta Conservation Plan is a collaborative effort to develop a plan to meet go-equal goals of restoring Delta ecosystem and restoring reliable water supply In 2009, the Delta Stewardship Council emerged as a result of State legislation known as the Sacramento-San Joaquin delta Reform Act; mandated to develop a Delta Plan to advance co- equal goals ◦ Mandated to develop a “Delta Plan” to advance the co-equal goals of ecosystem restoration and water supply reliability 7
- 8. Water Authority supports a “Delta Fix” ◦ Worked on persuading Legislature to pass 2009 Delta bill package, including Water Bond to cover state’s share of BDCP costs Water Bond delayed from 2010 to November 2012 ◦ Has expressed concerned with affordability of Delta fix and lack of firm financial commitment by MWD member agencies to pay for the fix 8

- 11. Purpose is to develop a long-term, science-based set of actions that will restore the Delta’s ecosystem and restore a reliable water supply ◦ Multi-species approach to endangered species protection ◦ Includes habitat conservation, conveyance improvements and other stressors control ◦ Provides regulatory assurance Led by Natural Resources Agency with collaboration with DWR, USBR, state and federal fishery agencies, water contractors and others DWR leads development of Delta Habitat Conservation and Conveyance Program (DHCCP) ◦ Environmental analysis, preliminary engineering designs, geotechnical studies and other feasibility evaluation for conveyance 11
- 12. North Delta Diversion - primary diversion point North Delta Diversion, used in conjunction with the existing South Delta Diversion, to maintain water quality, and minimize impacts to fish South Delta Diversion, operates on its own when the North Delta Diversion is non- operational during periods for maintenance or repair 12
