Christmas week storms will bring showers to Bay Area skies, dump snow on the Sierra Nevada mountains

Christmas will be a soggy one this year as another round of wet weather approached the Bay Area, kicking off a week of rain, according to the National Weather Service.  “It’s a rare setup in the Pacific where it’s sending low pressure, one of the bigger drivers of rain, coming down from British Columbia and meeting up with us,” said NWS forecaster Brayden Murdock.  A cold front attached to the low-pressure system over the Pacific Ocean and off the coast of the Oregon-California border will rotate and push moisture towards Northern California, resulting in a steady band of rain that will bring showers with sporadic breaks over the region for several days. Another low-pressure system will move down Friday night into Saturday and deliver another helping of rain. … ”  Read more from the San Jose Mercury News here: Christmas week storms will bring showers to Bay Area skies, dump snow on the Sierra Nevada mountains

Rain this week could put S.F. in the top 10 wettest water years on record, officials say

The anticipated rainfall in the Bay Area this week could put San Francisco in the top 10 wettest water years on record, according to the National Weather Service.  San Francisco has seen 12.5 inches of rain since the start of the water year, which begins Oct. 1 and lasts through Sept. 30, 2022.

Will coming storms break California’s epic drought?

Water watchers were anticipating a possible “drought busting” series of storms over the Christmas holidays after a strong assist from mid-December storms.  The Dec. 14 storm brought about one to two inches of rain to a lot of the San Joaquin Valley floor, said David Spector, forecaster at the National Weather Service’s Hanford station. It also dumped about two to four feet of snow at high elevations in the Sierra Nevada mountains which will help with water supply when that snow melts and runs off in the spring, he added.  The rain helped boost some reservoir levels too. ... ”  Read more from SJV Water here: Will coming storms break California’s epic drought?

With another dry year looming, California moves to set new urban water use standards

” … In October, California Governor Gavin Newsom declared a statewide drought emergency and urged a voluntary 15% reduction in water use for California cities. So far, most areas are falling short of the target, and mandatory cutbacks are likely for next year.  In November, amid the deepening drought, the DWR and the State Water Resources Control Board (SWRCB) issued joint recommendations to the California State Legislature for new indoor residential water use standards, along with a study supporting the recommendations (hereafter the Indoor Residential Water Use Study, or IRWUS). ... ”  Read more from the Pacific Institute here: With another dry year looming, California moves to set new urban water use standards

Conservationists work with Central Valley rice farmers to preserve bird habitat

Drought-relief funding is being used to create critical, appropriate places for birds to shelter in the Central Valley, which is part of the Pacific Flyway.  More than 100 million birds of 400 different species use the flyway every year, a span that stretches from the Arctic to South America.  In the Central Valley region, human use has taken over 95% of the natural habitat that geese and ducks could use.  The seasonal habitat is key to support the birds, but the flooding of rice fields to help preserve the habitat could run afoul of drought measures, especially at a time when up to 70% of the habitat was disappearing because of the dryness this past year. … ”  Read more from Fox 40 here: Conservationists work with Central Valley rice farmers to preserve bird habitat

Coalition releases plan to protect bird habitat

A public-private partnership has released a 10-year plan to restore and protect bird habitat in the Central Valley that also provides significant benefits to local communities, including flood protection, increased access to recreation, and replenishment of groundwater.

To the water wise: On-farm recharge a solution for nut growers

On-farm recharge (OFR) and the lowered soil oxygen levels that result from the practice do not negatively affect the health and yield of pecans, according to research conducted by a California-based environmental engineering firm.  Bachand & Associates, in collaboration with a grower with Pacific Gold Agriculture, applied 40 feet of water to the grower’s 5.4-acre pecan plot in McFarland, CA, during a 46-day period in 2020 (early May to mid-June). This was the second of two consecutive summers of the pilot study.  Although oxygen levels expectedly dropped to low levels during both years, no negative impacts were reported. The research also identified best practices specific to OFR and siting that can shorten the duration of low oxygen. ... ”  Read more from Growing Produce here: To the water wise: On-farm recharge a solution for nut growers

‘Unprecedented’ water allocation for State Water Project

The Department of Water Resources (DWR) began the month with a disappointing initial water allocation for the State Water Project (SWP). Due to a fairly slow start to the 2022 water year and the current condition of water storage, expectations were for a conservative allocation. DWR has announced a zero percent allocation for SWP contractors.  “What the Department of Water Resources announced in December was unprecedented. They said that there would be zero water allocated. What was interesting in their announcement is they prioritized how they were planning on delivering water,” said Adam Borchard, Director of Government and Public Policy for the California Fresh Fruit Association. … ”  Read more from Ag Net West here: ‘Unprecedented’ water allocation for State Water Project

Sites Reservoir clears a critical funding hurdle

The atmospheric river storm that brought some rain and snow to the parched state may serve as a reminder that California is still waiting to build planned infrastructure for storing water in wet years for use in dry years.  The California Water Commission last week took a key step forward on funding four water storage projects. They now are eligible to receive funds from $2.7 billion earmarked for public benefits of new projects authorized through the Water Storage Investment Program.  The funds are a portion of the $7.1 billion authorized through Proposition 1, a water bond passed by voters in 2014.  While commission members did not formally award any funds, they voted to advance four projects as feasible for construction and eligible to receive bond money. … ”  Read more from Ag Alert here:  Sites Reservoir clears a critical funding hurdle

Radioactive contamination is creeping into drinking water around the U.S.

When Jeni Knack moved to Simi Valley, California, in 2018, she had no idea that her family’s new home was within 5 miles of a former nuclear and rocket testing laboratory, perched atop a plateau and rife with contamination. Radioactive cesium-137, strontium-90, plutonium-239 and tritium, along with a mix of other toxic chemicals and heavy metals, are known to have been released at the industrial site through various spills, leaks, the use of open-air burn pits and a partial nuclear meltdown.

Putting Israeli water technology to use worldwide

Water is the world’s most precious resource. No person or nation can survive without it. These facts are ringing ever more true as global fresh water resources are diminishing and demand continues to grow. The adoption of advanced water technologies will be vital in the world’s quest to meet this historic challenge.  Israel’s history with water is long and distinguished. As a nation that is comprised of 60 percent desert, water technology has been at the forefront of Israel’s innovation sector. … Due to similar climates, Israeli water technology has performed well in California.

Years later, restored wetlands remain a shadow of their old selves

A study of restored wetlands on the Danish island of Funen reveals that plant species richness remains extremely poor many years after wetlands restoration. It is widely assumed that restored wetlands will increase local biodiversity and come to resemble natural wetlands over time. However, more must be done to catalyze recovery according to the University of Copenhagen researcher behind the study.”  Read more at the University of Copenhagen here: Years later, restored wetlands remain a shadow of their old selves

Agriculture faces host of new state laws in California

Farmers and ranchers will find themselves subject to new laws in 2022 that will raise wages, redefine animals’ living arrangements and allow ranchers better access to livestock in evacuation zones.  Effective Jan. 1, California’s minimum wage rises to $15 per hour for employers with 26 or more employees at any time in a pay period. Those employing 25 or fewer people at all times in a pay period will see the minimum wage rise to $14 per hour in 2022 and to $15 in 2023.  Employers of 26 or more people will also owe overtime pay to agricultural employees after working eight hours in a workday or 40 hours in a workweek.

Resilience of the Yurok Tribe in the Klamath River Basin

Along the Klamath River, which runs through Oregon and Northern California, is a 44-mile stretch the Yurok Tribe calls home. They’ve claimed the title “great fishermen” of the region for more than 10,000 years. However, in 2017 the USDA declared the Yurok Nation a food desert because of its extremely limited access to food. The nearest grocery store is located 24 miles away from the reservation. Additionally, the Yurok tribe’s access to their indigenous Pacific Salmon has been depleted as a result of environmental and climate change. This state of emergency was dramatically exacerbated by the COVID-19 pandemic, which has led to increased housing, health, and economic problems for the community. In 2012, the USDA implemented a project to help the Yurok Tribe develop new methods of ensuring food security and food sovereignty. Today, tribe members are finding their own methods of adapting to changes in their environment while also continuing to embrace their traditional consumption practices. ... ”  Read more from the NYC Food Policy Center here: Resilience of the Yurok Tribe in the Klamath River Basin

Lake County Board of Supervisors makes no move to split Water Resources, Public Works

“The Board of Supervisors on Tuesday decided to take no action on a proposal from the County Administrative Office to consider once again splitting the Water Resources Department off from the Department of Public Works.  County Administrative Officer Carol Huchingson said she agendized the discussion because the county is anticipating a “considerable amount of infrastructure funding” in the next year or two thanks to the federal infrastructure bill.  She said the discussion was brought forward to enable the board to consider whether it would make sense to have the two departments separate in order to allow Public Works to focus on projects.  … ”  Read more from the Lake County News here: Board of Supervisors makes no move to split Water Resources, Public Works

Good fire project protects Caples watershed from Caldor Fire

The Caldor Fire was fueled by red-flag conditions and historically dry vegetation, and it became the second fire ever to burn over the crest of the Sierra Nevada. As the fire raged eastward toward South Lake Tahoe and Kirkwood Ski Resort, the Caples Creek watershed lay directly in its path. But unlike areas nearby, the upper Caples Creek watershed was undamaged by the fire.  Two years before the Caldor Fire, forest fuels in the Caples Creek watershed were reduced through a mix of prescribed fire and managed wildfire. The Caples Creek Watershed Ecological Restoration Project (Caples Project), inspired by the El Dorado Irrigation District, funded by the Sierra Nevada Conservancy, and completed by the Eldorado National Forest, played a key role in protecting the Caples Creek watershed and surrounding communities during the Caldor Fire. … ”  Read more from the Sierra Nevada Conservancy here: Good fire project protects Caples watershed from Caldor Fire

Residing in Southern California, we live in a semi-arid environment. Unless we want to dry up and blow away, we definitely need to capture and use the precious rain we get here, as your editorial noted.  But we also need to prioritize and encourage the use of residential greywater. Water usage in the Southland is based on a wasteful single-use model. Bath, shower and laundry water is used only once and then sent into the sewage system.  This water could be safely diverted for use on outdoor landscaping with an in-home greywater system. Using greywater has numerous benefits, including saving water, lowering bills, diverting water into aquifers and creating cooler micro-climates. … ”  Read more from the LA Times here: Letters to the Editor: How to make home greywater systems take off like rooftop solar

Desert shrubs cranked up water use efficiency to survive a megadrought

Shrubs in the desert Southwest have increased their water use efficiency at some of the highest rates ever observed to cope with a decades-long megadrought. That’s the finding of a new study from University of Utah researchers, who found that although the shrubs’ efficiency increases are unprecedented and heroic, they may not be enough to adapt to the long-term drying trend in the West. “The Southwest is in a really dry period,” says Steven Kannenberg, postdoctoral research associate in the U’s School of Biological Sciences, “and this is further evidence of how much the ‘megadrought’ has impacted plant functioning and how anomalous this period is.” ... ”  Read more from Science Daily here: Desert shrubs cranked up water use efficiency to survive a megadrought

Fitch: Challenges ahead for utilities, but not enough to weaken ratings

U.S. water and sewer utilities will see some weakening in their financial profiles over the next several months, effectively reversing a trend of steadily declining leverage in recent years as utilities limited the rate of debt growth and posted robust operating margins. Part of the reason for the change is the wide-reaching ripple effect of the global coronavirus pandemic.  As a result, Fitch Ratings expects a reduction in cash reserves and a gradual rise in sector leverage through fiscal 2023 due to robust capital expenditure growth in fiscal 2021 and over the medium term. In Fitch’s base case scenarios, leverage is expected to rise by more than 20 percent across the rated portfolio from fiscal 2020 to fiscal 2023. … ”  Read more from Water Finance & Management here: Fitch: Challenges Ahead for Utilities, But Not Enough to Weaken Ratings
