The Bay Area is preparing for the second atmospheric river storm to soak the region this rainy season and alleviate the dire drought conditions in Northern California. There will be a slight chance of rain on Friday night into Saturday morning, with less than 0.10 of an inch forecasted in the North Bay, according to the National Weather Service.
Water rising beneath the ground, pushed up by intruding salt water as sea levels rise, now impacts thousands of toxic waste sites throughout the San Francisco Bay Area. A six-month investigation by NBC Bay Area found that the threat from rising groundwater isn’t decades in the future but, in some cases, may be imminent. In many hot spots from the North Bay to the South Bay, UC Berkeley scientists told the Investigative Unit they’ve recorded groundwater already at or near the surface.
Three successive storms will surge in from the Pacific Ocean this week, forecasters said Tuesday, bringing what may be the most rain in nine months to drought-stricken Northern California and offering a promising start to winter after two years marked by record wildfires and dry conditions.
Two of those storms look like atmospheric rivers — narrow, moisture-rich storms that play a critical role in the state’s water supply. The first, which was set to arrive late Tuesday night and continue into Wednesday morning, is likely to be a moderate storm. But another big one shaping up for Sunday night was upgraded to a category 5 on Tuesday, the highest in a five-level scale.
The Santa Clara Valley Water District, which is the main wholesale water provider in Santa Clara County, on June 9 declared a drought emergency and called on all residents to reduce water use 15% from 2019 levels to preserve supplies.
In August, the most recent month for which data is available, countywide water use dropped by 9%. That was an improvement from a 6% drop in July, but still is significantly under the goal.
Here is the percentage change in water use between August 2019 and August 2021 at the 13 cities and private water companies the Santa Clara Valley Water District serves.
Amid California’s worsening drought, Pleasanton city officials on Tuesday are expected to declare a local drought and water shortage emergency, and require residents to reduce their water usage by 15%. The Pleasanton City Council will vote at Tuesday’s meeting. In a report accompanying the council’s agenda, staff urged council members to make such declarations after board members with the Zone 7 Water Agency voted to do the same in September. The water agency, which serves the cities of Livermore, Pleasanton, Dublin, San Ramon and parts of Dougherty, said Tri-Valley customers are falling short on water reduction compared with 2020.
How dry? The region received a little more than a third of normal precipitation from Oct. 1, 2020, to Sept. 30, 2021, according to data from the National Weather Service — a common occurrence for the past several years, which bodes ill for a region already at the worst “exceptional” level on the U.S. Drought Monitor map.
Bay Area water agencies have saved nearly 10 times more water than the state average in the past year.
Collectively, 58 Bay Area water districts saved an average of more than 10% in July 2021 compared with the same time last year, according to new statistics from the State Water Resources Control Board.
California is running out of water. That’s the harsh assessment by experts who say 90% of the state is dealing with drought conditions with the threat of mandatory statewide water restrictions looming.
The most glaring indications of the drought in the Bay Area are the local reservoirs. The reservoirs during the last drought were relatively full and offered a temporary buffer to a major water shortage. That is not the case this time around.
With the state in the grips of a historic drought, reservoirs in Santa Clara County are at extremely low levels, as seen in a new video from the county’s water provider.
Santa Clara Valley Water, which provides for and manages the water needs of two million people in the county, released a new video Wednesday illustrating the dire state of the county’s reservoirs.
The Bay Area water system is a byzantine patchwork of agencies — more than 50 in all — that provides water to customers. Some are the ones you see on your water bill. Others are middlemen that provide water to local agencies at the wholesale level.
And some of that water makes a long journey. Southern California has the reputation for tapping far-flung sources for its water needs, but the Bay Area is in the same boat.
