Flooding rains and record snow in California last week marked another extreme swing of the state’s climate pendulum. The widespread downpours triggered mudslides that damaged homes and roads near some of the huge fire scars from last summer, and also brought some of the water the state will need to end a months-long hot and dry streak and douse a record-setting wildfire season that extended into January.
Fresh off a week filled with rain and snow due to an atmospheric river, water conservation may not be top of mind for everyday Californians.
NBC Bay Area Meteorologist Rob Mayeda just broke down some figures from this latest storm. In a Friday tweet he says, “Sierra Snowpack Surge: Up to 66% of average from just 40% one week ago. Biggest rains for the Central and Southern Sierra.”
While the recent precipitation may make the 2011-2017 California drought seem like a distant memory, a couple of laws passed by the legislature at that time are set to rain down policy on water agencies throughout the state.
Starting in November of 2023, California will enact a statewide indoor water use standard of 55 gallons per person per day. Local water agencies could be fined $10,000 a day by the state if they fail to meet the standard.
Although wetlands cover less than 4% of the Earth’s surface, 40% of all animal species live or reproduce in them. One-third of all organic matter on our planet is stored in places like the gigantic Pantanal wetland in western Brazil, the Sudd floodplain in southern Sudan or the Wasjugan Marsh in western Siberia.
This updates a post from December on the likelihood of California entering a second dry year. Normally, a second dry year brings drought operations for California’s overall water system operations.
Today, it is even likelier that California is entering a multi-year drought.
Precipitation conditions have improved somewhat with a nice atmospheric river this last week, but remain 51% of average for this time of year for the Sacramento Valley. (San Joaquin and Tulare basins are 61% and 47% of historical seasonal average precipitation so far.) Snowpack has improved somewhat with very recent storms, but is about as scarce as the precipitation.
California’s increasingly volatile warming climate is making droughts more intense, and complicating water management. A just-launched commodity futures market for the state’s water provides a new tool for farmers, municipalities and other interested parties to ensure against water price shocks arising from drought-fueled shortages.
Taking a Wall Street approach to an essential natural resource has prompted both fear and hype. Will California experience a new Gold Rush in water? Will speculation boost the cost of water? Perhaps both the fear and the hype are unwarranted.
If there were any doubts that the climate is changing in the Colorado River Basin, 2020 went a long way toward dispelling them, thanks to yet another year of extreme weather.
Unprecedented wildfires, deadly heat waves, withering drought—the many indicators of the climate mayhem that scientists have been warning about for years—ravaged the landscape, claiming dozens of lives and causing billions of dollars in damage.
Colorado endured an unprecedented wildfire season. And so did California, in some cases burning where the wounds were still fresh from the epic fires of 2018. Utah experienced its driest year ever, and persistent high temperatures killed more people in Arizona than ever before. Monsoon rains that typically bring relief throughout the region were a no-show for the second summer in a row and now are being called the “non-soon.”
Mayors and county supervisors in towns along the Colorado River were already upset five months ago when the state water agency endorsed an investment company’s plan to take water from farmland near the river and sell it to a growing Phoenix suburb.
Now, they’re incensed that the agency, which initially suggested holding back a large portion of the water, changed its stance and will let the company sell most of the water to the town of Queen Creek.
Since the early 1920s, the Long Valley plains east of Yosemite have inspired comparison to a rustic Western paradise — an idyllic frontier where sparkling creeks meander through lush pastures, waters teem with feisty trout and sage grouse make ostentatious displays of romance.
There is an adage in California that goes, “Whiskey is for drinking and water is for fighting over.”
But instead of fighting, the California Water Commission is looking for opportunities to hear from local agencies on water infrastructure projects.
The CWC recently wrapped up a series of public workshops intended to determine the opportunity for a state role in financing water conveyance projects that meet the challenges of a changing climate.
A battery storage demonstration project already providing a carbon-free source of electricity to California’s grid is about to be tested to see how well it can work on microgrids.
Located on a bluff at a San Diego Gas & Electric substation in Bonita, the energy storage project uses vanadium redox flow battery technology that stores electricity when the grid has excess supply and then discharges the energy when the power system needs it.
