Scripps Collaboration to Optimize Water Management & Supply

The San Diego County Water Authority is partnering with the renowned Scripps Institution of Oceanography at UC San Diego to better predict atmospheric rivers and optimize water management before, during and after California’s ever-changing seasonal storms.

Atmospheric river storms produce 40%-60% of the West Coast’s annual precipitation and are responsible for the majority of flood damage in the region. Predicting and managing this is challenging due to unpredictable and changing snowmelt and rainfall.

To study this, Scripps’ Center for Western Weather and Water Extremes (CW3E) introduced the Water Affiliates Group, which brings together relevant science and water industry expertise to enhance reservoir operations along with California’s changing climate.

Wildfire Threat Expected to Intensify Across California This Week

Hot, dry conditions and intense winds across California are threatening to reinvigorate what has already been the worst fire season in state history, officials warned on Tuesday.

La Niña and California’s New Water Year

It’s that time of the year in California, when water managers, climatologists and meteorologists look at the factors that determine what the winter will bring during Water Year 2020-21 (October 1, 2020 – September 30, 2021).

The National Oceanic and Atmospheric Administration recently said that La Niña conditions are present in the tropical Pacific, “with an approximately 85% chance of La Niña lasting through the winter.” Forecasters currently think this La Niña will be on the stronger side. For California, those conditions typically mean a drier winter, with increasingly dry conditions heading into 2021.

Gómez and Jacobs on the Green New Deal, Climate Injustice

If San Diego’s urban core were a human heart, then the 53rd Congressional District would be, geographically, its left ventricle. The political battle to represent its people is one between two liberals: former environmental justice advocate and San Diego City Council President Georgette Gómez and Sara Jacobs, the granddaughter of a Qualcomm co-founder who also chairs a childhood poverty organization called San Diego for Every Child.

Vast New Reservoir in South Orange County Gets Its First Drops of Water

Right now, it’s just a huge hole in the hills off Ortega Highway in San Juan Capistrano. Really huge, as it’s designed to hold 1.6 billion gallons of water.

It’s still dry as dirt, but promises to be a central component of future water supplies for the 165,000 people served by the Santa Margarita Water District. While the district currently imports 100% of its drinking water from  the Colorado River and northern California, the new Trampas Canyon Reservoir is part of a plan to generate 30% of potable water supplies locally and to recycle more wastewater.

Water Agencies Assist in Fighting Valley Fire

The Sweetwater Authority and the Otay Water District collaborated with multiple agencies during the recent Valley Fire in San Diego County. Water infrastructure played a key role in the firefighting effort.

Cooperation and collaboration are critical elements during wildfires. Both water agencies worked with multiple responders, including U.S. Forest Service firefighters, CALFIRE and SDG&E, to ensure the safety of crews and keep a safe, reliable water supply flowing for their customers.
