Contracting Opportunities




The Coast to Crest Trail section, previously closed to allow for construction and to protect public safety, is now open for daily use. For more information please read the Coast-to-Crest Trail and Environmental Documents section below.

Project Description

The Lake Hodges Projects are part of the San Diego County Water Authority's Emergency Storage Project, a system of reservoirs, interconnected pipelines and pumping stations designed to make water available to the San Diego region in the event of an interruption in imported water deliveries.

The Lake Hodges Projects will connect the city of San Diego’s Hodges Reservoir, also called Lake Hodges, to the Water Authority’s Olivenhain Reservoir. The connection provides the ability to store 20,000 acre-feet of water in Hodges Reservoir for emergency use. The connection will also allow water to be pumped back and forth between Hodges Reservoir and Olivenhain Reservoir. From Olivenhain Reservoir, water can be distributed throughout the region by the Water Authority’s delivery system.

When water is transferred downhill from Olivenhain Reservoir into Hodges Reservoir, it will generate up to 40-megawatts of peak hydroelectric energy, enough power to annually sustain nearly 26,000 homes. This energy will help offset project operating costs and support future Water Authority projects. The Lake Hodges Projects will also help keep Hodges Reservoir at a more constant level during dry seasons, capture runoff during rainy seasons and prevent spills over Hodges Dam.

The Lake Hodges Projects construction has four components:

  • Pipeline Tunnel – a 10-foot diameter underground pipeline, contained in a 1.25 mile long tunnel, connecting the two reservoirs,
  • Pump Station – a pump station to move water back and forth between the two reservoirs and generate electricity,
  • Electrical Switchyard – an electrical switchyard providing electricity to the pump station and sending electricity from the pump station to a local transmission system, SDG&E will build one part and the Water Authority will build adjacent equipment,
  • Inlet-outlet Structure – an inlet-outlet structure below the water surface that draws and discharges water between the Hodges Reservoir and the pump station.

Work began in 2005 and is expected to be completed in late 2010.

Lake Hodges Projects Fact Sheet

Coast-To-Crest Trail And Enviornmental Documents

Trail Status: On July 1, 2010, the 1.1-mile-long segment of the Coast to Crest Trail, located within the Lake Hodges Project’s construction site, was reopened for everyday use. During construction of the Lake Hodges Projects, the trail segment was fenced-in and closed to protect public safety and allow for construction. On May 1, 2010, the trail segment was first opened up for use on Saturdays and Sundays. The remaining fencing along the trail segment will be progressively removed throughout construction.

The nearly 55-mile long Coast to Crest Trail will extend from Del Mar to Volcan Mountain, just north of Julian. Information on the trail is available at www.sdrp.org/trails

Community Meeting Summaries

Lake Hodges Community Landscape Committee

The Water Authority formed the Lake Hodges Community Landscape Committee to provide community input to help design and develop the future landscaping of the Lake Hodges Projects. Landscaping will be limited to sections surrounding the Lake Hodges pump station building site, along the Coast to Crest Trail within the project site, and at the windsurfer parking lot just south of the pump station. The committee, comprised from community members from Del Dios, Lake Hodges Hills, Lake Hodges Native Plant Club, and the San Diego Windsurf Association, met with Water Authority staff from September 2007 through January 2008.

Meeting #3 - Summary Jan. 24, 2008
Meeting #2 - Summary Sept. 27, 2007
Meeting #1 - Summary Sept. 8, 2007

Landscaping Status: The Water Authority has selected a landscape contractor to install native vegetation and restore the area around the Lake Hodges site that was disturbed during construction. The landscape contractor will begin work in late spring or early summer 2010. The Lake Hodges Community Landscape Committee provided over 30 recommendations that were incorporated into the final landscape plan.
