Pictured above are some awesome Save the California Delta Alliance volunteers right before heading out to the Rio Vista Bass Derby Festival. We will be doing socio-economic surveying to prove just how problematic these tunnels will be for our Delta economy.

Come out and enjoy the festival and be sure to stop by the STCDA table to pick up a sign, T-shirt, or banner if you don’t already have yours!

Make sure to keep updated with all our upcoming events and stay connected so you can help STOP THE TUNNELS!

The Delta as a Place – A National Resource to Protect

About the Delta - Intro
The Delta

Delta Farmlands




Boating & Recreation


The Delta is 1,000 miles of scenic waterways, twists and turns that take the explorer from quaint historic cities, through channels lined with trees and tules, past large tankers moving up the main channel to Stockton, and fishermen catching bass in the small sloughs. The Delta is enjoyed by recreational boaters out for a day of waterski and wakeboard fun and by boaters anchoring out, surrounded by calm water, and enjoying the sunsets with Mount Diablo in the distance. The Delta can only be truly explored by boat and deserves to be protected as a National Recreation Area.

The California WaterFix/Tunnels Project would

  • Destroy the remaining salmon runs (More …)
  • Scar many of the nine Historic Legacy Towns of the North Delta
  • Destroy farming in the Delta (by salt water intrusion)
  • Wipe out South Delta boating:
    • Wipe out South Delta water ski/wakeboarding sloughs (More …)
    • Block Connection Slough and impact Middle River
    • Destroy the peaceful Mildred Island Anchorage (More …)
    • Make South Delta waterways salty, polluted, stagnant
    • Encourage invasive weeds and toxic blue-green algae
  • Cause economic ruin for Delta communities

One of their plans would even wall up the South Delta, blocking boats from going to/from Discovery Bay to the rest of the Delta!
