Metropolitan’s share ~ 25%

Includes work completed by the BDCP Steering Committee effort

1.0 - 1.5

Exports will be minimal for 1.5 to 3 years following an earthquake

Water Quality & Salinity Management

ObjectivesImprove export quality to meet Public Health standards & reduce treatment costsSupport actions to minimize salinity imports Meet 500 mg/l blending goal

Some Basin Plans have low TDS objectivesCould restrict extended recharge of high salinity Colorado River water *

SummaryDelta is critical to California’s water supplySouthern California is committed to conservation and local supplies for future growth and diversification

1.1 MAF of conservation and local resources will be developed to meet future needs

Storage has been developed to manage “big gulp/little sip”Stable imported supplies are needed for reliability
