Underground Tunnels Proposed For Calif. Water Woes

WASHINGTON (AP) — Federal and state officials threw their support Wednesday behind the construction of two underground tunnels as the best option for restoring California’s freshwater delta and meeting the needs of farmers and Southern California cities.

The diversion of water from the Sacramento-San Joaquin Delta to croplands and urban areas has furthered the decline of the largest estuary in the West. Officials are trying to find a solution that would reduce the ecological stress on the delta without harming the state’s agricultural economy.

Under the plan, two tunnels that are 33-feet in diameter and 150 feet below the surface would deliver water from north of the delta to the south. Water users would pay the tab, an estimated $13 billion. The tunnels would take about 10 years to construct.

The plan drew immediate protests from environmental groups, who said it doesn’t include specific goals that would measure success in protecting salmon and other endangered species. They also said it failed to contain measures that would lead people to conserve water.

The Bay Delta Conservation Plan is a federal and state initiative that would determine a framework for dealing with the declining health of the delta, as well as the increasing demand for its water. One of the leading players in the negotiations, the Westlands Water District, pulled out of negotiations months ago.

The announcement seemed designed to give stakeholders and the public a sense of progress.

“The status quo is not acceptable. The status quo will only result in a continuing and endless cycle of conflict, litigation and paralysis,” Secretary of Interior Ken Salazar said during a conference call summarizing the plan to reporters.

Salazar and other officials also said they still considered Westlands a part of the planning process.

“This is the only game in town, and we’re hopeful they’ll be full and robust participants as we move forward,” Salazar said.

Officials said the key elements to the plan were restoring tens of thousands of acres of marshland and floodplains, and developing a new system of moving water around the delta.

In recent years, court decisions aimed at protecting endangered fish have restricted water deliveries from the delta and have spelled major losses for growers in the state’s farm belt who rely on the delta’s water to irrigate their crops.

The Kern County Water Agency called the plan an important development in coming up with a strategy for restoring the delta.

Agency officials, however, said they were concerned that the proposal leaves open the amount of water supply that the tunnels could provide.

State officials only said that modeling suggests that annual water exports would be more reliable and greater than current exports.

    what about building a desalinization plant on the ocean beach for the L.A. area?

  • Connor Gilliland

    Ditto on that, its ridiculous that a much more practical solution is not being discussed much, we should be using our greatest asset, the ocean. Of course, that would actually make sense, and hence why its not being done. Typical of government.

    If you think about it, the tunnels are prob the best idea in the end. Building water plants on the ocean for more water does not help the delta like they wish to do. These billions is not just for building tunnels but also to redevelop the delta to make it what it once was before CA drained it all. These tunnels will also bring in more water for agriculture and the growing population in LA. Water plants will only get the environmentalist more up in arms saying it will kill the whales little shell creatures. Too bead it will take so long to build and prob will never see the light of day until it is to late.

    For 13 billion you can cover the calif aqueduct and stop the evaporation of a great percentage of that water going up in thin hot air through the desert. So you double the amount of water delivered for the same water being used now.

    Yesterday’s announcement by State and federal officials about moving forward with the BDCP is welcome news for most California water users. It would have been unanimous except for the expected response from certain environmental groups who continue to play a delaying game against restoring reliable water supplies and a restored Delta ecosystem. Their immediate objection to proposed tunnels, which would provide additional safeguards for fish and be paid for by water users, is unreasonable and only results in continued delays and increased costs.
