CCWD's Expanded Los Vaqueros Reservoir
Ensures High Quality Water,
Reliability & Environmental Protection

Project Summary:

The Contra Costa Water District has expanded its Los Vaqueros Reservoir, with construction finishing up in fall 2012.

The reservoir's capacity grew from 100,000 acre-feet to 160,000 acre-feet. The dam has increased in height by 34 feet, and is now 226-feet high.

The additional water storage will help ensure high-quality water deliveries to customers, reliability during drought and protections for Delta fisheries and the environment.
The project cost $120 million.
