The Big Creek Dams project would build a roller-compacted concrete dam between the upper and lower reservoirs. This dam would be higher than the existing dams and would hold the volumes currently stored in the lower and upper reservoirs combined. The project would take three to four years to construct.

 

By enlarging the upper Big Creek Reservoir and replacing it with a dam that will sustain seismic activity, the risk of dam failure will no longer be a hazard.

 

Sustaining the environment is a critical component of the Big Creek Dams Project. We can accomplish our water supply goals while enhancing natural habitat and lessening our reliance on already stressed water resources.
