Carlsbad Sand Dredging Project Protects Beaches, Water Supply

/in , , /by /10 News (San Diego)by Jonathan Horn

Heavy equipment will dominate a stretch of Carlsbad’s beach near the old Encina Power Plant for the next month.

Crews are funneling thousands of cubic yards of sand per day onto the beach, not only to protect the shoreline, but also the water supply.

Poseidon Water, which runs the desalination plant adjacent to the old power plant is running the project. The desalination plant converts 50 million gallons of ocean water to drinking water per day, providing 10 percent of the region’s water supply.

Drought-Stricken West Holds Out For More Than Just Dry Snow

It’s a picture-perfect scene — the snow-dusted Sandia Mountains providing a backdrop to the dormant willow and cottonwood trees lining the Rio Grande.

While the recent snow has provided a psychological salve to the pains of a persistent drought, it won’t go far in easing the exceptional conditions that have taken hold of New Mexico over the past year.

Water Authority Exploring New Aqueduct Plan

Quoted: San Diego County Water Authority

Addressing the San Diego region’s limited local water supplies with innovative ideas is something the San Diego County Water Authority has become known for. Using expertise gained from decades of successful planning and projects, the Water Authority is developing strategies to reduce the future cost of water that sustains the economy and quality of life across the county.

Those efforts are ramping up in early 2021, following a Water Authority Board decision to continue assessing the potential for a new aqueduct to transport San Diego’s low-cost, high-priority water supplies from the Colorado River to San Diego County.

Landfalling Atmospheric Rivers Increase in First Quarter of Water Year 2021 Over 2020

/in , /by

A Scripps Center for Western Weather and Water Extremes report shows that more atmospheric rivers have made landfall over the U.S. West Coast in the first four months of Water Year 2021 compared to the previous period in 2020.

The four months of Water Year 2021 experienced a total of 35 landfalling ARs over the U.S. West Coast, six more than the first four months of Water Year 2020, according to the CW3E quarter year summary released February 11.

Key takeaways from the CW3E update on atmospheric rivers

• The first four months of Water Year 2021 experienced a total of 35 landfalling ARs over the U.S. West Coast, 6 more than the first four months of Water Year 2020.
• Water Year 2021 also experienced more than twice as many strong or greater ARs (14) compared to Water Year 2020 (6).
• While Water Year 2021 saw more ARs in its first 4 months compared to Water Year 2020, a large majority of those ARs were
strongest over the Pacific Northwest (Oregon and Washington).
• The average landfall latitude thus far in Water Year 2021 was 45.9°N compared to 43.9°N during the first half of Water Year 2020.
• The lack of landfalling ARs over Southern California and Baja California has resulted in much drier conditions over the southwestern U.S. compared to WY 2020.

Atmospheric River-NOAA-WNN-CW3E

A partnership with the San Diego County Water Authority and the Scripps Institution of Oceanography at UC San Diego seeks to optimize water management to better predict atmospheric rivers before, during, and after those seasonal storms.

In August 2020, Scripps Center for Western Weather and Water Extremes (CW3E) launched the Water Affiliates Group, which brings together cutting-edge science and hands-on water industry experience to enhance reservoir operations in light of the changing climate. The Water Authority has a long-running alliance with Scripps and is among six founding water agencies statewide.

CW3E and its partners will share and support best practices in forecast-informed reservoir operations, increase research around atmospheric rivers and droughts, and develop strategies for mitigating flood risk and increasing water supply reliability.

Opinion: Why is Arizona Growing When Groundwater is Shrinking? We’re Finally Having This Debate

/in , /by /AZ Centralby Joanna Allhands

If our water supply is dwindling, why is Arizona still growing?

I get this question almost every time I write about groundwater. Readers say we should be doing a lot more to slow – or even cut off – the construction of new homes and farms.

That’s not likely to happen any time soon. But smart people are diving into the weeds of how we use this finite resource to fuel growth, and that makes me cautiously optimistic.

Opinion: Debate Begins Over $5 Billion Water Proposal for San Diego

Over two decades, I’ve watched opponents resist San Vicente Dam, the Carlsbad Desalination Plant, Olivenhain Reservoir, San Diego Pure Water and other projects because they refused a meaningful, fact-based dialogue. Thankfully, in each of those cases, a rational, long-term approach to securing our future prevailed.

California’s Rainfall is at Historic Lows. That Spells Trouble for Wildfires and Farms

/in , /by /The Guardian by Katharine Gammon

There’s a race on in California, and each day matters: the precipitation during winter that fuels the snowpack in the Sierra Nevada and fills groundwater supplies has been slow to start, and faltering at best. Northern California remains stuck in one of the worst two-year rainfall deficits seen since the 1849 Gold Rush, increasing the risk of water restrictions and potentially setting up dangerous wildfire conditions next summer.

Water Plant Cyberattack Is Wake Up Call, 20 Years in the Making

/in , , /by /Bloomberg Lawby Jake Holland and Bobby Magill

A cyberattack on a Florida water treatment plant underscores the need for strong security protections at the municipal level, attorneys and industry professionals say.

A hacker gained access to an Oldsmar, Fla. city computer on Feb. 5 and changed the level of sodium hydroxide, also known as lye, local authorities said. It isn’t yet known whether the breach originated from the U.S. or from outside the country. The Federal Bureau of Investigation is working with local authorities.
