The Southwest U.S. is mired in an ever-worsening drought, one that has left deer starving in Hawaii, turned parts of the Rio Grande into a wading pool, and set a record in Colorado for the most days of “exceptional drought.”
People around the world know San Diego for its beautiful, sunny, and mild weather. San Diego residents know our daily weather has more variety than visitors might imagine.
Climate is defined as the average weather conditions in an area over a long period, generally 30 years or more. German climate scientist Wladimir Koppen first divided the world’s climate into six regions in the early 1900s.
We welcome the new year with heavy hearts about the recent events in our nation’s Capitol and a renewed commitment to civility and respect at every level of government.
At the same time, we are maintaining our concentration on our priorities for the year, which are numerous and significant. I’m focused on advancing San Diego County’s interests as we continue to fulfill our mission of making sure that our region has safe and reliable water supplies at an affordable price, which is critical to maintaining our economic competitiveness and sustaining our wonderful quality of life.
Here’s some good news about how the Water Authority is putting San Diego County first in 2021:
A valve at the base of the Loveland Dam near Alpine was opened Monday, allowing billions of gallons of water to thunder down the valley toward Sweetwater Reservoir in Spring Valley. “It’s a spectacle that is hard to forget,” said Hector Martinez, Chairman of the Sweetwater Authority “Very powerful! I almost feel the ground shaking when the water is being released.” The gushing valve is a sight to behold, and thanks to the massive transfer, South Bay water customers might be looking at their water bills with similar amazement.
Wall Street’s reputation as one of America’s premier innovation machines can only be enhanced by a new futures contract that began trading publicly on Dec. 7. It allows investors to bet on the price of water in California.
Those who take the gamble are effectively betting that the spot price for water will rise during the life of the contract; they’ll pocket the difference. Sellers are betting that the price will fall.
Beside a river that winds through a mountain valley, the charred trunks of pine trees lie toppled on the blackened ground, covered in a thin layer of fresh snow. Weeks after flames ripped through this alpine forest, a smoky odor still lingers in the air.
The fire, called the East Troublesome, burned later into the fall than what once was normal. It cut across Rocky Mountain National Park, racing up and over the Continental Divide. It raged in the headwaters of the Colorado River, reducing thick forests to ashes and scorching the ground along the river’s banks.
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.”
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.
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.
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.”
“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.
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.
