Getting Ready for Construction on San Vicente Dam Raise
San Vicente Dam
Good news for San Diego County: construction starts soon on the San Vicente Dam Raise, the last major component of the Emergency Storage Project.

The San Vicente Dam Raise project will increase the height of the existing dam by 117 feet. This will more than double the reservoir's water storage capacity. Construction is expected to begin before summer.




Lake Hodges Cofferdam Gets the Job Done
Lake Hodges Cofferdam
How do you build an inlet-outlet structure and its connecting
tunnel on the bottom of a reservoir? You use a cofferdam! The Lake Hodges Projects contractor installed a temporary cofferdam to keep the reservoir water out of the construction area. This spring, the cofferdam will be dismantled and removed - it accomplished its job.


A Closer Look at Pipe Installation
San Vicente Pipe InstallationPipe installation for the San Vicente Pipeline is well under way in the western portion of the tunnel. To date, crews have placed about 180 pipe segments in the tunnel, almost two miles long. The contractor anticipates completing pipe installation for the five miles between the West and Central shafts this spring.



Testing Equipment in the New San Vicente Pumping Facilities
Surge Control TankWith construction largely complete, over the next several months each piece of equipment in the pump station and surge control tank will undergo extensive testing to help ensure it works properly when needed. The pumping facilities will deliver water from San Vicente Reservoir to the San Vicente Pipeline and ultimately to San Diego County residents during an emergency.
