BAY DELTA CONSERVATION PLAN OVERVIEW

“BRIEFING ON A DELTA FIX”

ACWA REGIONS 9 & 10 JOINT PROGRAM

OCTOBER 19, 2012

Presentation Outline

• Brief overview of the State Water Project

• Delta overview and history

• Current efforts BDCP update BDCP EIR/S overview

DWR Mission and Operations Goals• DWR Mission

• To manage the water resources of California in cooperation with other agencies, to benefit the State's people, and to protect, restore, and enhance the natural and human environments

• DWR Operation Goals• Collect water when available and deliver

when needed• Operate and maintain system to achieve

maximum safety, reliability, and flexibility

• Supply good quality water for municipal, industrial, agricultural, and recreational uses and environmental benefit

• Operate within regulatory and system constraints

DWR Project Overview• Nation’s largest state owned and

operated water delivery system• Serves 25 million Californians and

755,000 acres of farmland• Includes: Storage Facilities, Pumping

Plants, Pumping-generating Plants, Hydroelectric Plants, about 700 miles of Canals and Pipelines

• California’s fourth largest energy producer of hydropower

• Other benefits include: flood control, recreation, Delta salinity control, environmental benefits, and power grid stability

• 65,000 acres of Restored Tidal Habitat

• 10,000 acres of Restored Floodplain• 20 Levee Miles of Restored Channel

Margin• Enhanced Floodplain Habitat in the

Yolo Bypass• Thousands of acres of Restored and

Protected Riparian & Terrestrial Habitat

• More than 100,000 acres of Restored and Protected Habitat in the Delta over 50 Years• Up to 30,000 acres of restored habitat in next 15 years

HABITAT RESTORATION GOALS

CONSERVATION MEASURE 1: DUAL CONVEYANCEThe North Delta

Diversion would be the primary diversion point and would be subject to strict water operations rules

N

S

The North Delta Diversion would be used in conjunction with the existing South Delta Diversion when it is necessary to maintain water quality and safe for fish

N

S

The South Delta Diversion would be preferentially operated when safe for fish and when the North Delta Diversion is restricted

Alignments and Capacities

Gravity Flow Benefits Include:• Reduced energy

consumption and greenhouse gas emissions

• Installation of fewer transmission lines

Preliminary Draft – Subject to Change

• Gravity flow • Three proposed intakes and

three proposed pumping plants for a total of 9,000 cfs capacity

• Three state-of-the-art fish screens held to performance standards to protect passing fish

• Intermediate Forebay for temporarily storing the water pumped from the river

DUAL CONVEYANCE WITH PIPELINE/TUNNEL

Current Proposal

14

• Two tunnels to carry water 35 miles to the existing pumping plants in the south Delta, where it would be moved into existing aqueducts

• 840-acre forebay at Byron Tract

• Total power requirement-50 MW

• Continued use of South Delta SWP/CVP facilities

Preliminary Draft – Subject to Change

DUAL CONVEYANCE WITH PIPELINE/TUNNEL
