Opinion: Can One Atmospheric River End California’s Drought?

/in , , /by /California Water Blogby Andrew L. Rypel and Jay Lund

Given the quantity and intensity of last week’s rain, an obvious question is: ‘Is the drought over?’ Alas, the answer is a resounding no. But, the data are interesting and worth thinking about in more detail. As of now, the 8 station index in the northern Sierra registers 12.6 inches of cumulative precipitation. Because the water year just started (October 1), all of this came from the recent atmospheric river. It was an impressive storm, and set quite a few local one-day precipitation records.

June Moua started growing cherries, tomatoes and grapes in east Fresno County 10 years ago. Now she grows a few different types of crops. But her most profitable are the water-intensive Asian greens like mustard greens and bok choy.

Opinion: Conservation Is Critical During Drought, but Not the Only Solution

/in , /by /ACWAby Steve Lamar and Sean Bigley

Gov. Gavin Newsom has extended the drought emergency statewide and called on all Californians to redouble their efforts to conserve water. His call to action is critical even with the storms that recently soaked California, because we know that a lot more rain and snow will be needed to lift the state out of the drought.

The Governor’s approach to statewide conservation is laudable, as well, because it continues to empower water managers with matching local water supply conditions with conservation, rather than relying on statewide mandates. While conservation is a critical tool for saving water during a drought, it is only one of many actions that must be taken to address drought. Investing in water infrastructure and the ability of local water managers to diversify supplies are also essential to building climate resilience throughout the state.

California Drought: Key Talks Over Water Use Break Down, S.F. May Face Tighter Regulation

/in , /by /San Francisco Chronicleby Kurtis Alexander

For nearly three years, some of California’s biggest water users, including San Francisco, have been quietly meeting with the state to figure out how much water they should be taking from the San Joaquin River and its tributaries.

The talks were launched to prevent some of California’s mightiest rivers from drying up, and keep fish populations from disappearing, while still allowing cities and farms to draw the supplies they need. The vision was nothing short of a grand compromise on divvying up California’s water.

Opinion: California Should Create More Water – Much More

/in , /by /CalMattersby Jim Wunderman

Wouldn’t you know it? Just like washing your car, almost the moment I finished writing this article, the skies opened up.

I’d write one every day if it meant ending our water woes. But it tells you everything you need to know about California’s dire water situation – that the atmospheric river that recently pummeled Northern California and other parts of the state doesn’t even begin to make a dent in our drought.

And it highlights the urgency for California to create more water. Much more.

On Sunday morning, during the atmospheric river event in Northern California, scientists from the Center for Western Weather and Water Extremes (CW3E) at the Scripps Institute of Oceanography at UC San Diego and their partners at Yuba Water Agency launched weather balloons to gather data on the AR and its impacts on reservoirs.

The San Diego County Water Authority partnered with the Scripps Institution of Oceanography, Center for Western Weather and Water Extremes, at UC San Diego in 2020 to better predict atmospheric rivers and improve water management before, during, and after those seasonal storms. The Center and its partners share best practices in forecast-informed reservoir operations, increased research around atmospheric rivers and droughts, and develop strategies for mitigating flood risk and increasing water supply reliability.)

Storms Bring Pause for State Drought Orders in Modesto and Beyond. They Could Return

/in , , /by /The Modesto Beeby John Holland

The recent storms allowed California to suspend the drought curtailment orders that had been imposed during the summer. Cities and irrigation districts now are free to capture river runoff that had been unavailable because of the orders. Officials warned that they could fall back into place if the state gets another stretch of dry weather.

‘Atmospheric River’ Drenches Drought-Stricken California

/in , /by /AP Newsby Olga R. Rodriguez

A powerful atmospheric river storm that swept through California set rainfall records and helped douse wildfires. But it remained to be seen how much of a dent it made in the state’s drought.

The weather system weakened as it moved south but still dropped enough rain Monday evening to cause mudslides that closed roads in the San Bernardino Mountains northeast of Los Angeles. The atmospheric river storm, a long and wide plume of moisture pulled in from the Pacific, came ashore in Northern California over the weekend.

How Improved Atmospheric River Forecasting Can Help Keep Water Flowing in California

/in , , /by /ABC10by Monica Woods

Atmospheric rivers can bring dangerous flooding, but, without them, California can head into drought. Improving forecasts for these huge storms is a focus for the Center for Western Weather and Water Extremes to keep water flowing in the state.

Marty Ralph remembers living in Los Angeles in the 1980s when a huge rainstorm dropped nearly half the rainfall for the whole year in 12 hours. It was at that moment he realized he wanted to study these kind of storms
