GROUNDBREAKING FOR ANDERSON DAM TUNNEL PROJECT Valley Water reaches milestone in work at Anderson Dam

SAN JOSE —This summer, Valley Water will begin work to build a larger outlet tunnel next to Anderson Dam, which will allow us to release more water safely during major storms or emergencies. On July 7, Val-

ley Water will be joined by elected officials and community leaders for a groundbreaking ceremony at Anderson Dam. Where: Anderson Dam and Reservoir. Who: Federal, state and local elected officials,

including Valley Water board members. Santa Clara County is currently dealing with a drought emergency. Further challenging our local water supply, the Federal Energy Regulatory Commission ordered Anderson Reservoir to be drained for public safety as Valley Water strengthens the dam. This means our largest drinking water reservoir will be down – and unable to store drink-

ing water – for the next 10 years as we construct the Anderson Dam Tunnel Project and Seismic Retrofit Project. Completing our work at Anderson Dam is critical as we contend with climate change and the inevitability of future droughts. The Anderson Dam Tunnel Project is the first step in our work to strengthen the dam. Our contractor for the Anderson Dam Tunnel Project began mobilizing at the site in June, and construction of the 1,700-

foot long tunnel is expected to begin this summer. We estimate it will take approximately three years to complete the tunnel. The tunnel project is part of the larger Anderson Dam Seismic Retrofit Project to strengthen the existing dam and spillway so it can safely withstand a large earthquake. That project is estimated to start in 2024 and will last about seven years. Once completed, Valley Water will again be able to fill Anderson Reservoir to capacity.
