CCWD Principles for Participation
• The project improves water quality and reliability for CCWD • The project enhances the Delta environment• The project protects and enhances the fisheries and terrestrial species
benefits provided by the existing Los Vaqueros Project• The project preserves and increases the recreational opportunities of the
Los Vaqueros Project• CCWD must maintain control of watershed and operation of the reservoir• The project protects and reimburses the financial investment made by the
CCWD customers who financed the existing $450 million Los Vaqueros Project
• The proposal would be placed before the voters of the Contra Costa Water District
8
Project Overview
• CALFED is studying whether an expanded Los Vaqueros Reservoir can meet CALFED and Bay Area water agencies’ objectives
• Water Quality• Reliability• Environmental
Enhancement
• Expansion from 100,000 acre-feet up to 500,000 acre-feet maximum capacity
9
What are Important Water Quality Parameters?
• Salts– From seawater intrusion or other discharges -- Cause
taste and corrosion problems; impede water recycling• Organics and Bromide
– Harmful chemical by-products can be formed when water is disinfected
• Pathogens (bacteria or viruses)– From runoff, discharges, or human activities -- Treated
with filters and disinfection
10
What is Reliability?
• Emergency Storage– Storing water to protect against a disaster (earthquake,
power failure, levee failure, pipeline failure, or chemical spill)
• Drought Storage– Storing water in wet years for use during dry years
• Flexibility– Ability to stop Delta diversions to protect fish without
disrupting water users
11
Environmental WaterImproves Fisheries & Habitat
• Environmental Water Account (EWA)– Integral part of CALFED Program to restore the Delta– Like a bank account: Assets controlled by fisheries agencies to
enhance Delta fisheries and habitat• Protecting fish by shutting off pumps (changing the timing of diversions)• Providing flows to enhance fisheries• Assets can include water, storage, conveyance capacity, and
operational flexibility
• Federal Wildlife Refuges– Water supply to 10 wildlife refuges in the San Joaquin Valley
• In-stream Flows– Water supply to provide stream flows for fish at critical times

Existing Los Vaqueros Project
• Provides Emergency Storage– Protects against a catastrophe in the Delta
• Improves Water Quality– Changes the timing and location of diversions– Stores water for blending when Delta water quality is
poor• Enhances Delta Environment
– State-of-the-art fish screens– Flexible timing and location of diversion

Questions and Discussion
• Workshop Process and Public Review• Project Purposes and CALFED Goals
• Improve Bay Area water quality and reliability• Enhance Delta environment
• Current Operations– Delta Operations
• Water Quality• Reliability• Delta Enhancement
– Existing Los Vaqueros Project
21
Meeting Agenda
• Agenda– 2003 Studies Activities and Available Information– Current Delta Operations– Los Vaqueros Expansion Operations
• Operating Scenarios• CCWD and Bay Area Water Quality and Reliability• Delta Enhancement
– Facilities, Construction Schedule, and Costs
22
Operating Scenarios
• Developed full range of possible ways to operate an expanded reservoir– Environmental water priority– Bay Area reliability priority– Multi-purpose (combination)
• Compared to future conditions without an expansion
• Determined there are projects that could meet CALFED objectives and CCWD Principles
23
Operating Scenarios Constraints
• Delta Protection– Operate within all regulatory requirements– Use only surplus flow and existing water rights / contracts to fill
reservoir• Fishery Protection: conservative
– Assumed two month “no-fill” period in spring for fish protection– Operate within all fish protections measures
• Protection for Other Users– No injury to water right holders or contractors
• Analyzed 70 years of rainfall patterns– Including critically dry (1977) and extended drought (1928-
1934 and 1987-1992) years

Drinking Water Quality Benefits
• Major Findings– Water Quality
• All scenarios would improve drinking water quality for CCWD
• All scenarios would improve drinking water quality for Bay Area agencies served by the South Bay Aqueduct
28
Drinking Water Quality Benefits
• As the state continues to grow there will be increased pressure on the Delta and declining water quality
• Expanded Los Vaqueros Reservoir would improve water quality for CCWD and Bay Area water agencies– New intakes would reduce salts and bromide– Larger intakes allow faster reservoir filling when quality is better– Deeper reservoir with multiple intakes reduces organics
• These improvements result in– Reduced public health risks– Improved taste – customer satisfaction– Reduced treatment costs and improved ability to meet existing
and future water quality regulations
29
Drinking Water QualityBenefits for CCWD
More high quality water delivered to CCWD customers during extended droughts
• Before the existing reservoir, CCWD could not provide high quality water during droughts or in any dry periods– No water available for blending
• With the existing reservoir, CCWD can deliver high quality water through a 3-year drought
• With an expansion, CCWD could deliver high quality water through a 6-year drought

Reliability Benefits
• Major Findings– An expanded Los Vaqueros Reservoir could be
operated to provide more reliable water supplies• 60,000 to 120,000 acre-feet of water in drought

Potential BenefitsDelta Enhancement
• Expanded Los Vaqueros Reservoir Enhances Delta Environment– Reduces impacts to fisheries from existing SBA
Diversion• State-of-the-art fish screens• Flexible timing of diversion
– Creates storage and flexibility for Environmental Water that could allow
• Shut downs at state and federal pumps when fish are present (up to 158,000 acre-feet per year)
• Water for wildlife refuges• Water for in-stream flows upstream of Delta
45
Potential BenefitsDelta Enhancement
Existing State Pumps–High volume–No outlet for fish–High fish losses
Existing & Potential Los Vaqueros Diversions–Low volume and velocity–Fish can swim past screens–Very low fish losses
Fish Screen
46
Potential BenefitsDelta Enhancement
• Expanded Reservoir creates opportunity to store Environmental Water– EWA owns capacity in an
expanded Los Vaqueros Reservoir
– Fill reservoir when no fish are near pumps and water quality is good
– Normal export pumping– Deliveries to South Bay
agencies out of Los Vaqueros Reservoir
When Fish are not Present
47
Potential BenefitsDelta Enhancement
• Expanded Reservoir Creates Opportunity for Environmental Water– No filling Los Vaqueros– Deliveries to South Bay
agencies out of Los Vaqueros Reservoir
– EWA reduces or stops export pumps
When Fish are near Pumps
48
Potential BenefitsConclusions
• An expanded Los Vaqueros Reservoir could meet CCWD Principles 1 & 2– The project improves water quality and reliability for CCWD – The project enhances the Delta environment
• The project could meet CALFED objectives– Provide substantial water quality and reliability benefits for Bay
Area water agencies, including CCWD– Provide state and federal resource agencies with water for the
environment
