Stop the Destructive Delta Tunnels

California's water, environment and wildlife urgently need your help.

Currently dry regions in the south of the state get water pumped from the far north via the San Francisco-San Joaquin Bay Delta. Limits on this pumping help protect endangered species: The pumps must be shut off or pumping reduced periodically in order to protect endangered Delta smelt from getting sucked into the pumps.

Unfortunately a newly proposed "solution" to these protections, called the Bay Delta Conservation Plan, would divert the water around the Delta with two massive underground tunnels. This solution will further harm the smelt and other wildlife that depend on the Delta. 

The Center for Biological Diversity is actively challenging the plan to making sure that endangered species are not harmed by the tunnels, but we need your help.

Please take action using the form below. Tell state and federal agencies to protect endangered species and reject the Delta Plan and its twin tunnels.
