What If It’s Too Warm to Snow? Water Managers Across the West Need to Adapt, Report Says

/in , , /by /Arizona Republicby Lindsey Botts

Arizona and the West could see their water supplies drop by as much as 30% by the middle of the century as warmer temperatures lead to less snowfall, reducing runoff into rivers and reservoirs, changing vegetation cover and altering wildlife habitat.

Those are the findings of a team of researchers led by Erica R. Siirila-Woodburn and Alan M. Rhoades at the Lawrence Berkeley National Laboratory, who published a paper looking at the likelihood of a “low-to-no snow” future. Their analysis, published in the journal Nature Reviews Earth and Environment, also estimates when and where to expect the effects of a low-to-no snow climate disaster.

Department of Water Resources Investing Heavy in Water Facility Rehabilitation

/in , , /by /Valley Voice

Today, the California Department of Water Resources initiated a $100 million funding program to restore capacity to portions of the California Aqueduct, San Luis Canal, Delta-Mendota Canal, and Friant-Kern Canal lost to land subsidence occurring during the last several decades.

“Fixing these canals is an important foundational piece to ensure a reliable and climate resilient water supply for California,” said DWR Director Karla Nemeth. “It enables us to move water during very wet conditions, which will be essential to adapting to more extreme weather. Restoring capacity in our existing infrastructure provides a critical link in diversifying water supplies by supporting groundwater replenishment throughout the Central Valley and water recycling projects in Southern California. It’s a prudent investment in our water future.”

‘Snow Drought’ is Threatening the Western US, and That Could Become a Massive Problem

The western United States has built their water infrastructure on a melting foundation, and unless we do something about global warming, scientists worry the consequences will be catastrophic.

Billions for Climate Protection Fuel New Debate: Who Deserves It Most

/in , /by /New York Timesby Christopher Flavelle

The new infrastructure law signed by President Biden includes almost $50 billion to protect communities against climate change, the largest such investment in United States history and a recognition that the effects of warming are outpacing America’s ability to cope.

Mr. Biden has insisted that at least 40 percent of the benefits of federal climate spending will reach underserved places, which tend to be low-income, rural, communities of color, or some combination of the three.

California Regional Meeting to Feature Panels on How to Meet Climate Goals

/in , , /by /National Hydropower Association Mentioned: San Diego County Water Authority

In 2016, California set a goal of reducing greenhouse gas emissions to 40 percent below 1990 levels by 2030. This is the most aggressive emissions reduction target in the United States. California Governor Gavin Newsom is directing California state agencies to accelerate the state’s progress toward its climate goals and is evaluating pathways for the state to achieve carbon neutrality by 2035.

Meeting these goals means a major shift in how electric power is generated and a greater reliance upon renewable sources, which, in turn, will lead to new kinds of investments, markets, and business practices.

One of the most promising pumped storage hydro solutions in California is the proposed 500-MW San Vicente Energy Storage Facility under consideration by a partnership of the San Diego County Water Authority and the City of San Diego.

A ‘No Snow’ California Could Come Sooner Than You Think

It was 55 degrees and sunny Thursday at Sugar Bowl Resort, where the opening day of the 2021 ski season — already delayed because of warm weather — was still listed as “TBD.”

“Winter hasn’t quite arrived in Tahoe yet,” officials wrote in a note about the postponement. “The team will be working nightly and ready to flip the switch when Mother Nature cooperates.”

But the mountain isn’t the only place feeling the pinch from lack of snow. A new study led by researchers at the Lawrence Berkeley National Laboratory found that dwindling snowpack across California and the western United States could shrink dramatically more — or in some cases disappear — before the end of the century.

Researchers Work to Keep Imperial Beach Above Water

/in , , /by /NBC 7 San Diegoby Joe Little

Every winter, Imperial Beach finds some of its streets and sidewalks underwater. This week, researchers from San Diego State and UC San Diego started digging groundwater wells to see how sea-level rise plays a role in that flooding. The sea-level impacts how shallow the water table is underneath the city.

“Flooding overall is a very, very big thing in Imperial Beach,” said Hassan Davani, Ph.D.

The SDSU researcher said most studies predict sea-level rise will significantly impact California as early as 2050. However, Davani said Imperial Beach can’t wait that long to protect itself.

California Water Districts to Get 0% of Requested Supplies

/in , , /by /APby Kathleen Ronayne

California water agencies that serve 27 million residents and 750,000 acres of farmland won’t get any of the water they’ve requested from the state heading into 2022 other than what’s needed for critical health and safety, state officials announced Wednesday.

It’s the earliest date the Department of Water Resources has issued a 0% water allocation, a milestone that reflects the dire conditions in California as drought continues to grip the nation’s most populous state and reservoirs sit at historically low levels. State water officials said mandatory water restrictions could be coming.

“If conditions continue to be this dry, we will see mandatory cutbacks,” Karla Nemeth, director of DWR, told reporters.

As Drought Worsens, Officials say Mandatory Water Cuts Likely Coming for Urban Californians

/in , , /by /The Sacramento Beeby Dale Kasler

With the drought showing no signs of abating, California officials announced Wednesday they plan to deliver almost no water from the State Water Project to begin next year — and suggested that mandatory cutbacks in urban usage could come if conditions stay dry.

Karla Nemeth, director of the Department of Water Resources, said the various cities and farm-irrigation districts that belong to the State Water Project — the elaborate state-run network of reservoirs and canals — are getting “essentially a zero allocation” to start 2022.
