INTRODUCTION
• Background
• Summary of California WaterFix (CWF) – Physical Components – Operations – Collaborative Science and Adaptive Management
Page 2
CWF FUNDAMENTAL PURPOSE AS DESCRIBED IN THE EIR/EIS
• To make physical and operational improvements to the system to restore and protect: – Ecosystem health – Water supplies of the SWP and CVP
south of the Delta – Water quality within a stable regulatory
framework, consistent with statutory and contractual obligations
Page 4
PHYSICAL COMPONENTS OF THE PROJECT
• 2 tunnels up to 150’ below ground designed to protect California’s water supplies
• 3 new intakes, each with
3,000 cubic-feet per second (cfs) capacity. Average annual yield of 4.9 million acre-feet

OPERATIONAL COMPONENTS
• CWF Initial Operational Criteria
• Real Time Operations
• Collaborative Science and Adaptive Management – Consistent with applicable water quality control plan requirements – Decision making coordinating with state and federal fish and wildlife
agencies. – The framework is developed consistent with existing state and federal
adaptive management programs
Page 12
CWF INITIAL OPERATIONAL CRITERIA
• Continued compliance with D-1641
• No change to Delta Cross Channel, Suisun Salinity Control Gate operations, or Fall X2
• Consistent with existing water rights
Page 13
CWF INITIAL OPERATIONAL CRITERIA (CONT’D)
• New criteria for: – North Delta Diversions Bypass
Flows – South Delta OMR – Head of Old River Gate – Rio Vista minimum flows – Potential spring outflow

COLLABORATIVE SCIENCE & ADAPTIVE MANAGEMENT
• Focused on – North Delta Diversion screen
design – Habitat restoration – Delta Operational Criteria
Page 16
COLLABORATIVE SCIENCE & ADAPTIVE MANAGEMENT FRAMEWORK
– Provides framework for targeted scientific research to address uncertainties and make adjustments over time
– Consistent with applicable water quality control plan requirements – Decision making coordinating with state and federal fish and
wildlife agencies – The framework is developed consistent with existing state and
federal adaptive management programs
Page 17
COLLABORATIVE SCIENCE AND ADAPTIVE MANAGEMENT (CONT’D)
• Key Concepts include: – Undertake collaborative science – Guide the development and implementation of scientific investigations and monitoring – Apply new information to management decisions and actions
Page 18
TESTIMONY OVERVIEW
• Engineering testimony will provide detail about mitigation for project construction
• Operations testimony will provide detail about existing and continued real time operations: – Real-time adjustments to North Delta
Diversion, south Delta facilities, and Head of Old River Gate to continue to operate to D-1641
