Dry Start to California’s Water Year

/in , , /by /Water News Network Quoted: San Diego County Water Authority

A dry start to California’s water year is reflected in the season’s first snow survey of the Sierra Nevada snowpack. The statewide snowpack is 52% of average for Dec. 30. On average, the Sierra snowpack supplies about 30% of California’s water needs.

“The first snowpack survey of the water year points to California’s climate variability, which is why a diverse water portfolio is needed to provide a reliable supply,” said Goldy Herbon, San Diego County Water Authority senior water resources specialist. “The Water Authority and its 24 member agencies have successfully diversified water sources, and continue to expand those sources, to ensure our supply meets the needs of the region’s 3.3 million people and its $245 billion economy.”

Why It’s Way Too Early to Worry About Rain Deficits in SoCal

Yes, it’s been pretty dry so far this winter, but there is no need to worry. The major winter storm that roared through Southern California Monday proved we can erase a month’s worth of rain deficit in one day. I recently explained how the climate where we live — the Mediterranean Climate — sees the majority of its annual rainfall in the winter months. In fact, a whopping 80% of Southern California’s annual rain and snow falls from December through March.

Climate Change Spells Trouble for the Colorado River. But There’s Still Hope

One of the best road trips I’ve ever taken was a sightseeing tour of the Colorado River, where it straddles the California-Arizona state line. I stood at the edge of Imperial Dam near the Mexican border, which diverts water to the farm fields of the Imperial Valley, then drove north to Cibola National Wildlife Refuge, home to lots of birds. I walked along the river in Laughlin, Nev., where there’s a hotel called the Colorado Belle that looks like a boat, and in Needles, Calif., where Snoopy’s brother Spike lives.

Billion-Dollar Disasters: The Costs, in Lives and Dollars, Have Never Been So High

Extreme weather will surely have its own chapter in the turbulent history of 2020. The human and economic toll of Covid-19 was already enormous this fall, when it became clear that 2020 was on track to break the previous record for big weather disasters, fueled in part by climate change. From the derecho that battered the Midwest with hurricane-force winds to unprecedented wildfires that scorched more than 700,000 acres in Colorado and gave California its worst fire season in history, weather and climate events like these represented only a few line items in the latest tally of the nation’s billion-dollar disasters.

Farmers Swap Out Irrigation Methods To Keep The Colorado River From Growing Saltier

/in , , /by /Aspen Public Radioby Jodi Peterson & KVNF

AJ Carrillo farms 18 acres outside of Hotchkiss, Colo., in the high desert of the Western Slope about an hour southeast of Grand Junction.  When he irrigates his peach orchard, water gushes from big white plastic pipes at the top of the plot and takes half a day to trickle down to the other end of his five-acre orchard. Carrillo is planning to convert his Deer Tree Farm from flood irrigation, which is commonly used in Western Colorado, to a new and much more efficient style of irrigation – microsprinklers.

Is Farming with Reclaimed Water the Solution to a Drier Future?

On a Saturday in late October, Carolyn Phinney stands hip-deep in a half acre of vegetables, at the nucleus of what will one day be 15 acres of productive farmland. “You can’t even see the pathways,” she says, surrounded by the literal fruits of her labors. The patch is a wealth of herbs, tomatoes, eggplants, peppers, kale, winter squash, and zucchini. So much zucchini — fruits the size of bowling pins hidden under leaves as big as umbrellas.

Dry Start to California’s Water Year

/in , /by

A dry start to California’s water year is reflected in the season’s first snow survey of the Sierra Nevada snowpack. The statewide snowpack is 52% of average for Dec. 30. On average, the Sierra snowpack supplies about 30% of California’s water needs.

The California Department of Water Resources manual survey at Phillips Station recorded 30.5 inches of snow depth and a snow water equivalent of 10.5 inches, which is 93% of the January 1 average at that location, according to DWR officials. The snow water equivalent,or SWE, measures the amount of water contained in the snowpack and is a key component of DWR’s water supply forecast.

While the Phillips Station measurement was positive, DWR’s electronic readings from 130 stations placed throughout California show the statewide snowpack’s SWE is 5 inches, or 52% of the December 30 average.

“The snow survey results reflect California’s dry start to the water year and provide an important reminder that our state’s variable weather conditions are made more extreme by climate change,” said DWR Director Karla Nemeth. “We still have several months left to bring us up to average, but we should prepare now for extended dry conditions. The Department, along with other state agencies and local water districts, is prepared to support communities should conditions remain dry.”

Water supply diversity meets regional demand

“The first snowpack survey of the water year points to California’s climate variability, which is why a diverse water portfolio is needed to provide a reliable supply,” said Goldy Herbon, San Diego County Water Authority senior water resources specialist. “The Water Authority and its 24 member agencies have successfully diversified water sources, and continue to expand those sources, to ensure our supply meets the needs of the region’s 3.3 million people and its $245 billion economy.”

The supply sources include water from the Claude “Bud” Lewis Carlsbad Desalination Plant, where ten workers volunteered to live on-site in 2020 to keep the water flowing during the coronavirus pandemic.

Sierra Nevada Snowpack-Snow Water Content

Climate change brings less snow

When the Sierra Nevada snowpack melts, it feeds into rivers and is stored in reservoirs across California. Reservoirs are tapped as needed during the dry months. However, state officials again said that climate change is affecting California’s snowpack, as more precipitation falls as rain and less as snow. And they urged Californians to make water conservation a “way of life.”

“Today’s survey brought a first glimpse of how the state’s snowpack is shaping up, but there is a lot of winter still ahead,” said Sean de Guzman, chief of DWR’s Snow Surveys and Water Supply Forecasting Section. “While the dry conditions during late summer and fall have led to a below average snowpack, it is still encouraging to have the amount of snow we already have with two of the three typically wettest months still to come.”

DWR conducts five snow surveys at Phillips Station each winter near the first of each month, January through April and, if necessary, May. Guzman said the next survey is scheduled for February 2.

Dismal California Snowpack is Bad Sign for Water Supplies

/in , /by /San Francisco Chronicleby Kurtis Alexander

A month into California’s peak storm season, the lack of wet weather is beginning to weigh on the state’s water supply.

The snowpack in the Sierra and southern Cascades, which provides as much as a third of the water used by California cities and farms, is about 55% of average for this time of year. It hasn’t been this low at this time since 2017, when the state was emerging from a five-year drought.

Trump Signs Spending Bill That Could Send Millions of Dollars to the Salton Sea

/in , /by /Palm Springs Desert Sunby Mark Olalde

President Donald Trump on Sunday signed a roughly $900 billion stimulus package meant to tackle both COVID-19 relief as well as federal spending. Tucked in the 5,593-page-long law, courtesy of Southern California Democrats, are provisions that hold the potential to unlock millions of dollars of new federal spending to address the Salton Sea.

The bill notably modifies the Water Resources Development Act by authorizing the U.S. Army Corps of Engineers to expedite a study on the feasibility of constructing a perimeter lake around the Salton Sea. It’s one of the large-scale plans floated to address the lake’s woes, and this move could speed up the process.

The law also includes more than $150 million for the Army Corps to carry out such studies on water issues at the Salton Sea and elsewhere.

California is helping lead the charge in reducing greenhouse gas emissions, but more needs to be done as climate change remains the state’s top environmental issue in 2021 issue, according to top environmental lobbyists in Sacramento. Other issues on their agenda include plastic pollution, recycling, wildlife protections, and greater repair and reuse of appliances and electronic products before they are discarded.
