Bay Delta Conservation Plan (BDCP)
 Comprehensive Conservation Strategy for the
Sacramento-San Joaquin Delta
 Designed To:
 Restore and Protect Ecosystem Health, Water
Supply, and Water Quality (Co-Equal Goals)
 Create a Stable Regulatory Framework
 Results In 50-Year Permit:
 Long-term Permits/Authorization Under State and
Federal Endangered Species Acts For Operations of
State Water Project (SWP) & Central Valley Project

No BDCP Benchmarks
 BDCP incorporates a “decision tree” framework
• High outflow (low water supply)
• Low outflow (high water supply)
 High and low outflow scenarios incorporate different
environmental flow requirements
 Developed corresponding scenarios if the BDCP is not
implemented
• Apply the same requirements to the existing conveyance and
habitat
• Difference between the BDCP and no-BDCP cases isolates the
benefits of new conveyance and habitat
