Delta Conveyance Project (aka “The Tunnel”)

What’s the project?

Have you heard of the “Twin Tunnels,” or the “Delta Tunnels?” How about the “California Water Fix,” “WaterFix,” “Delta Conveyance Project,” or “Bay Delta Conveyance Plan (BDCP)?”

Each of these are different names for projects that all involve building at least one underground tunnel to export water from the Delta. Now the plans are for one tunnel instead of two, but that doesn’t mean the new plan is any better for the residents and ecosystems of California. Click here to learn why.

Take Action!

Participate in a meeting

Also, the Delta Conveyance Design and Construction Authority (DCA) is conducting engineering and planning for the tunnel project for the Department of Water Resources (DWR) and meets the third Thursday of every month. The DCA is comprised of member water districts that hope to received water supplies from the tunnel. Consider tuning in to the next meeting and commenting if you can. The DCA needs to hear about the environmental problems with the project and the other better ways to meet their agencies’ water supply needs that won’t irreparably harm the Delta. More information about future meetings can be found at https://www.dcdca.org/.

On April 17, 2020, the Environmental Council of Sacramento (ECOS) and Habitat 2020 submitted our comments, under the California Environmental Quality Act (CEQA), on the latest iteration of the Delta Conveyance Project.

Our concerns include the following:

  • Project needs to be defined clearly
  • Appropriate alternatives must be considered for the project as a whole
  • Appropriate Alternatives must be considered for infrastructure components
  • Impact of mechanically assisted flows in the tunnels need to be analyzed
  • Analysis needs to assume that all Reusable Tunnel Material (RTM) will need to be disposed, rather than repurposed
  • Accurate transportation impacts must be provided
  • Impacts to Stone Lakes National Wildlife Refuge need to be avoided
  • The full impacts of transmission lines need to be included
  • Transmission line strikes need to be analyzed for foraging Sandhill Cranes

April 7, 2020

The Delta Counties Coalition submitted a letter requesting a Stay of Public Processes for Delta Conveyance Planning During the Novel COVID-19 Pandemic. Below is an excerpt from their letter.

The DCC believes that disruptions caused by COVID-19 will deprive citizens, local communities, and other stakeholders the opportunity to engage with agencies on important matters, and this includes the Delta Conveyance Project. We also feel that virtual meetings are an inadequate substitute to a temporary stay of public processes around Delta conveyance. Remote meeting options are most appropriate for situations where an agency must conduct its business without delay, for instance in relation to the COVID-19 crisis and other operational necessities. Public participation via webcast or telephone cannot provide the robust public input necessary for the controversial Delta Conveyance Project. Many residents of the rural Delta and in underserved urban areas adjacent to the Delta lack reliable internet service to participate in meetings held via webcast.
