The Newsom administration on May 2 shelved the plan to build twin Delta Tunnels and announced it will start a renewed environmental review for a single Delta Tunnel.
As the Delta smelt moves closer and closer to extinction in the wild, the Department of Water Resources reported that it is taking formal steps to withdraw proposed permits for the WaterFix project and begin a renewed environmental review and planning process for a smaller, single tunnel project that will protect a critical source of water supplies for California.
Thus, this announcement marks the end of the twin tunnels project that Arnold Schwarzenegger began in 2007, itself a revival of the peripheral canal plan that the voters overwhelmingly rejected in the November 1982 election. After beginning his third term as Governor, Jerry Brown continued to pursue the Bay Delta Conservation Plan, as it was called, until it was renamed the California WaterFix in 2015.
Today's actions implement Governor Gavin Newsom's direction earlier this year to modernize the state's water delivery infrastructure by pursuing a smaller, single tunnel project through the Sacramento-San Joaquin Delta, according to a statement from the Department of Water Resources. The project is needed to protect water supplies from sea-level rise and saltwater intrusion into the Delta, as well as earthquake risk. It will be designed to protect water supply reliability while limiting impacts on local Delta communities and fish.
However, Newsom continues to support one smaller Delta Tunnel that is based on the same controversial concept of diverting water from the Sacramento River under the Delta to fulfill the coequal goals of ecosystem restoration and water supply reliability.
A smaller project, coordinated with a wide variety of actions to strengthen existing levee protections, protect Delta water quality, recharge depleted groundwater reserves, and strengthen local water supplies across the state, will build California's water supply resilience, claimed Natural Resources Secretary Wade Crowfoot.
DWR Director Karla Nemeth took action to rescind an array of permitting applications for the WaterFix project, including those in front of the State Water Resources Control Board, California Department of Fish and Wildlife, and federal agencies.
