Project OperationsThe Project generates water supply for local and public benefits:

• Local Water Supply o Capture and regulation of surplus Kings River flows in to

groundwater banking and conjunctive use facilities7

• Public Benefit Water Supplyo Capture and regulation of surplus Delta flows into Semitropic

Groundwater Bank8

o Banked water exchanged for SWP deliveries9

o Exchange water available North of Delta ecosystem purposes10

Public BenefitsThe Project provides Public Benefits11, as defined by WSIP, including:

• Ecosystem Improvement to Delta fisheries and historic Tulare Lake bed• Flood Management• Recreation Improvement to the historic Tulare Lake Bed• Emergency Response• Project benefits must be quantified and monetized for future (2030 and

2070) conditions.

Ecosystem Improvement12

Project integration with SWP/CVP facilities to transport and store surplus Delta flows will improve threatened and endangered salmonid survival by:• Improving temperature on the Sacramento River below Shasta/Keswick

complex,• Increasing egg-to-fry survival, and• Increasing adult salmon that return to spawn.

Ecosystem adaptive management options highlight Project flexibility.Total Monetized Public Benefit for 2030 = $636 million Total Monetized Public Benefit for 2070 = $514 millionTotal Non-Monetized Benefit = 10,240 acres of seasonal, intermittent

open-water habitat12 From Section 3.1.1 of Tulare Lake Storage and Floodwater Protection Feasibility Report (GEI Consultants, Aug 2017)

Ecosystem Adaptive Management

Flood Control Improvement13

Kings River flood flow capture will reduce flood risk to prime agricultural lands and disadvantaged communities within the Kings River and Tulare Lake region.

• Kings River flood flows are directed to the San Joaquin system and lost under current operations.

• Total Monetized Public Benefit = $3 million (Flood Damage Reduction)

13 From Section 3.1.2 of Tulare Lake Storage and Floodwater Protection Feasibility Report (GEI Consultants, Aug 2017)

Emergency Response14

The Project improves system capability to respond to emergencies or natural disasters in the Delta.

• Ability to make SWRU withdrawals of banked water would provide a water supply to South of Delta SWP users.• 40,000 acre-feet of water for 2030 conditions• 20,000 acre-feet of water for 2070 conditions

• Total Monetized Public Benefit for 2030 = $96 million• Total Monetized Public Benefit for 2070 = $72 million

14 From Section 3.1.4 of Tulare Lake Storage and Floodwater Protection Feasibility Report (GEI Consultants, Aug 2017)

Recreation Benefits15

The Project would support waterfowl and migratory bird populations along the Pacific Flyway, and enhance recreational birdwatching opportunities for area residents and outdoor-oriented tourists.

• Total Monetized Public Benefit= $.25 million

WSIP Non-Public Benefits17

The Project also provides Non-Public Benefits, such as:

• Improved Water Supply and Operational Flexibility for the SWP• Improved Groundwater Banking and Conjunctive Use• Improved Local and Regional Water Supply Reliability• Improved Water Quality in the SWP and Local Groundwater Basin
