Pacheco Reservoir Expansion
A collaboration between Valley Water, the San Benito County Water District, and the Pacheco Pass Water District, the Pacheco Reservoir Expansion Project is a strategic and long-term investment toward ensuring a more reliable supply of safe, clean drinking water in the face of climate change.
The project will boost Pacheco Reservoir’s operational capacity from 5,500 acre-feet to up to 140,000 acre-feet, enough to supply up to 1.4 million residents with water for one year in an emergency. The project will also reduce the frequency and severity of water shortages during droughts, protect our drinking water supply and infrastructure, and improve fish habitat.
In February 2021, Valley Water held two virtual public scoping meetings and detailed five dam alternatives being evaluated for the Pacheco Reservoir Expansion Project as part of the California Environmental Quality Act process. Valley Water is also evaluating an option of no expansion. Click on the photos tab at the right to view the images.
