Water agency amends plans for Delta Tunnel

The Press

The California Department of Water Resources (DWR) amended a federal permit application last week to change to the preferred tunnel route for the proposed Delta Conveyance Project (DCP), a move that has Delta advocates questioning DWR’s long-term plans for the South Delta.

The agency said the move was necessary to align the federal permit application – known as a Section 404 and filed with the U.S. Army Corps of Engineers (USACE) – and a draft environmental impact report that is currently being prepared by DWR. The so-called Bethany Alternative will be the preferred project in both documents, though DWR stressed that the change does not indicate that a decision has been made with regard to the route the tunnel will take if the project is approved.

The Bethany Alternative tunnel route bypasses the Clifton Court Forebay near Tracy, a design aspect that has caused concerns among those who advocate on behalf of Delta interests.
