New Federal Forecast: What the Coming La Niña Means for California Rains

After enduring the driest stretch of years in our history, and then logging the wettest spell on record this past winter, befuddled Californians have one question on their minds these days: What’s next? In two words: La Niña. But whether the water temperature pattern hatching right now in the Pacific Ocean will leave the Golden State high and dry this winter as it’s often done in the past is anyone’s guess. Particularly since it’s quite similar to the pattern we saw last year, and we know how that turned out.

CVP Reservoirs Start with Comfortable Carryover

Federal water storage among California’s Central Valley Project (CVP) reservoirs started the 2017 water year with 8.9 million acre feet, nearly twice held in the same six key reservoirs scattered about the state a year earlier. This is 145 percent of the 15-year average carryover of 6.2 million acre feet, still a “safe level” with respect to flood control or the possibility of a dry winter, according to David Murillo, regional director for the U.S. Bureau of Reclamation.

District OKs Smaller Water Tunnel Plan for California

A Northern California water agency has voted for a stripped down, less costly version of Gov. Jerry Brown’s $16 billion project to build two massive water tunnels under the Sacramento-San Joaquin River Delta. The Santa Clara Valley Water District’s board voted 7-0 Tuesday to adopt a set of principles endorsing a project with just one tunnel. The San Jose Mercury News says the vote further throws the future of one of Brown’s major construction priorities into doubt.

Cost of Oroville Dam Repair Nearly Doubles As Unexpected Problems Emerge

The reconstruction of Oroville Dam’s flood control spillway is likely to cost as much as $500 million, state officials said Thursday, as design changes and unexpected additional work has inflated the cost of the project. Originally budgeted at $275 million, the repair has grown to cover a greater level of protection for the dam’s emergency spillway – whose near failure in February sparked the evacuation of 188,000 downstream residents – as well as unforeseen problems in the bedrock beneath the main spillway, said Erin Mellon, a spokeswoman for the state Department of Water Resources.

The Energy 202: Interior Greenlights Desert Water Project, Prompting Call for Investigation

Last week, the Interior Department sent a letter to Cadiz Inc. that the company long had hoped to receive. For years, the renewable resource company had been trying to build a drinking-water pipeline between land it owned over an aquifer in the Mojave Desert and thirsty residents of Southern California. To help get the go-ahead from the federal government, it hired the law and lobbying firm Brownstein Hyatt Farber Schreck to help grease the wheels in Washington.

OPINION: California Officials Must Maintain Pressure on Cadiz Aquifer Project

Like just about everything else that involves water, the Cadiz Inc. Mojave Desert aquifer project saga has been one of many ebbs and flows. There were two new developments in this situation recently. The federal government reversed itself this month and gave its blessing to the massive project to transfer as much as 16.3 billion gallons of groundwater per year from beneath the desert floor near ecologically sensitive public lands to thirsty urban communities via a long pipeline.

Silicon Valley Water Board Wants Delta Tunnels Downsized

The $17 billion “California WaterFix” project reached a tipping point Tuesday after a Silicon Valley water district voted against Gov. Jerry Brown’s approach in favor of a less expensive, scaled-back version. The San Jose-based Santa Clara Valley Water District agreed to “conditionally support” California WaterFix – a plan to divert water from the Sacramento-San Joaquin River Delta through a pair of 40-foot-wide, 35-mile-long tunnels – but said the state will have to consider cheaper alternatives before the district can commit hundreds of millions to the water project.

Santa Clara Voted On — Something

The Santa Clara Valley Water District says it voted to support the California WaterFix today. But did it? The Mercury News describes the vote as a rejection of the Fix, because Santa Clara’s board conditioned its approval on “considering an approach” that incorporates one tunnel instead of two tunnels. The Sacramento Bee also describes the vote as a rejection of Brown’s plan, though not prominently in the headline as the Merc did.

5,000-Mile Long ‘River In The Sky’ To Deliver Heavy Rain, Feet Of Snow To Northwest

An atmospheric river is poised to funnel gigantic amounts of rain and snow to the Northwest over the next few days. As much as 15 inches of rain is forecast in the mountains along with several inches in coastal areas, including Portland and Seattle. It could be Seattle’s wettest weather since February, the National Weather Service said. There is also a risk of flash flooding in western Washington and northwestern Oregon on Thursday as a result of the heavy rainfall, the weather service warned.

Oroville Dam Flood Plan Calls for Keeping Lake Lower Than Usual

A plan has been prepared for flood control operations this rainy season at Oroville Dam, which call for keeping the lake lower and aggressively releasing water if the water level rises above trigger points. Up to now, the dam has been operated under rules drafted by the Army Corps of Engineers in 1970, which set a maximum lake surface elevation target of 848.5 feet above sea level for November through April, and 870.1 feet in May.
