Our coalition aims to protect Santa Clara County’s ratepayers and the environment, as well as working ranchlands, from this wasteful and high-risk new dam.

We raised our voices, and we stopped the dam! After years of advocacy, @valleywater is walking away from the costly Pacheco Reservoir project. Thank you to our community partners including @SaveMountDiablo, @SierraClubCA, Center for Biological Diversity, Save the Bay,

Concrete dams destroy habitat. Groundwater storage doesn’t. It’s the smarter, safer, and more sustainable way to manage water in California. #StopPachecoDam #SustainableSolutions #GroundwaterMatters

As we look back on the history of our National Park System, we can’t help but feel proud and grateful. These places tell America’s story, preserving our history, culture, and natural wonders for generations to come.

Tree Hugger. Red Squirrels have very flexible ankle joints. When a squirrel wants to climb down a tree it rotates its feet 180 degrees and hangs from its back legs. In human terms that would mean rotating your feet around until they were pointing backwards. #NatureLovers

Flooding Pacheco Pass would destroy centuries of indigenous history. @ValleyWater should make more sustainable water solutions and protect what cannot be replaced. #StopPachecoDam #CulturalPreservation

Still no consistent timeline. Still no transparency. And now, costs are soaring past $5 billion. Why is Valley Water still pushing the Pacheco Dam? #StopPachecoDam #SmartWaterSolutions

The @CA_WaterCom just gave the 2.7+ billion-dollar Pacheco Dam project a reality check by unanimously voting not to increase funding levels for inflation due to @valleywater's failure to make progress on the project. Now, it has been delayed to 2029 and is falling apart fast!

The proposed Pacheco Reservoir expansion would flood over 1,500 acres of protected land, destroying rare habitats, block critical wildlife corridors, and threaten species like the California tiger salamander and Crotch’s bumble bee. All this for a project with skyrocketing costs,

Meet the Crotch’s bumble bee, a once-common native pollinator now critically endangered. One of its last habitats? Pacheco Pass, land that would be flooded by the Pacheco Dam. Protect the bees. Protect the land. #WorldHoneyBeeDay #CrotchsBumbleBee #StopPachecoDam
