Take Action


  • Donate. Donations will be used to educate the taxpayers and hire scientists to combat the tunnels (e.g., scientific research into better alternatives and to evaluate the negative impacts on the South Delta if the tunnels proceed).

    Or send a check made out to “STCDA” to:
    P.O. Box 1760
    Discovery Bay, CA 94505

  • Write letters to the editor of newspapers throughout California. See hints about how to get your letters published. A list of email addresses for the Editors of various newspapers is provided here.

  • Display a Lawn Sign. Click on the “Display a Lawn Sign” link to the right.

  • Stay Informed. Click “Become a Member” to the right to receive periodic news and updates about the Delta.

  • Show up at Delta Water Events!


    We need to continue to make a presence at the BDCP and other water meetings. 400-500 people turn out at every Town Hall and Water Meeting held at the Discovery Bay Elementary School! Join your friends and neighbors and let the State know what you think about their plans that keep damaging the Delta.
