If San Diego’s urban core were a human heart, then the 53rd Congressional District would be, geographically, its left ventricle. The political battle to represent its people is one between two liberals: former environmental justice advocate and San Diego City Council President Georgette Gómez and Sara Jacobs, the granddaughter of a Qualcomm co-founder who also chairs a childhood poverty organization called San Diego for Every Child.
It’s that time of the year in California, when water managers, climatologists and meteorologists look at the factors that determine what the winter will bring during Water Year 2020-21 (October 1, 2020 – September 30, 2021).
The National Oceanic and Atmospheric Administration recently said that La Niña conditions are present in the tropical Pacific, “with an approximately 85% chance of La Niña lasting through the winter.” Forecasters currently think this La Niña will be on the stronger side. For California, those conditions typically mean a drier winter, with increasingly dry conditions heading into 2021.
Fortunately for the San Diego region, any impacts from La Niña will be lessened because of the region’s development of a diversified water supply portfolio. Following a record number of acres burned from wildfires in 2020, La Niña would only increase fire danger.

But, whether the forecasts come to fruition, and what that means for California’s water supply, won’t be fully known until next spring. What we know now is that the water year that just ended (October 1, 2019 – September 30, 2020) varied across the state.
While Northern California was mostly dry, parts of Southern California experienced above average precipitation, according to the California Department of Water Resources. The agency said that the water year ended below average and pointed to the impact of climate change on the California’s water supply.
“California is experiencing the impacts of climate change with devastating wildfires, record temperatures, variability in precipitation, and a smaller snowpack,” said DWR Director Karla Nemeth. “We must continue to invest in our infrastructure to prepare the state to cope with more extreme weather for the state’s needs today and in the future.”
For Water Year 2020, a lack of precipitation resulted in a snowpack of just 50% of average on April 1, as measured by the California Cooperative Snow Survey Program, making it the 10th smallest snowpack in California since 1950, according to the DWR. California’s reservoirs received just a third of the water runoff from precipitation and snowmelt that they did during the same time period a year ago.
The wet season got off to a slow start, but a series of storms in late November and early December pushed 2019 precipitation to near or above average in central and southern California, according to Goldy Herbon, San Diego County Water Authority senior water resources specialist.
“The wet start didn’t last with dry conditions taking hold over most of the state in January, and then most of California experienced its driest February on record,” said Herbon.
While precipitation picked up in March 2020 for Southern California, statewide snowpack in mid-March was only 38% of average.
“The dry north/wet south precipitation pattern continued in March and April, with some locations in Southern California setting many daily precipitation records, San Diego included, as northern California precipitation levels remained below average,” said Herbon.
Despite the below average year in northern California, Herbon said statewide water supplies are in “excellent shape” thanks to above average precipitation the previous year and good reservoir storage. DWR reports that statewide reservoir storage through the end of September 2020 was projected to be 93% of average.
In the San Diego region, a wet spring boosted rainfall totals to near or above normal.

The San Diego County Water Authority will host an online public information session on Oct. 27 about economic considerations related to the proposed Regional Conveyance System. The virtual event will run from 10 a.m. to noon. To reserve a spot, email .

In June of 2019, the Water Authority’s Board of Directors approved a study of the viability of a new regional conveyance system that would deliver water from the Colorado River to San Diego County and could provide multiple benefits across the Southwest.
The Phase A report, released in August 2020, found that building a new conveyance system to transport the region’s supplies from the Quantification Settlement Agreement is cost-competitive with other long-term strategies for meeting the region’s water needs.
At its August 2020 meeting, the Water Authority’s Board decided to continue the regional discussion about the study until November 19, at which time the Board is expected to decide whether to move ahead with Phase B of the study.

Each of the potential conveyance routes would connect to the tail end of the All-American Canal where it meets the Westside Main Canal in the southwest corner of Imperial Valley.
After a brief interlude of mild temperatures Saturday, a warm-up is forecast to begin Sunday as upper-level high pressure builds into California, the National Weather Service said. High temperatures will climb by several degrees on Sunday.
A few weeks after the devastating 2017 Tubbs Fire raged through parts of northern California, Gerald and Serene Buhrz returned to their Santa Rosa home, turned on the kitchen sink faucet, and were hit with a stinging smell.
A new experiment is looking into how drought conditions, like we’re currently in, can affect water traveling downstream the Colorado River. The pilot project involved shepherding water from a high mountain reservoir to the Colorado-Utah state line. The project is a partnership between Colorado Springs Utilities, Aurora Water and Pueblo Board of Water Works.
Right now, it’s just a huge hole in the hills off Ortega Highway in San Juan Capistrano. Really huge, as it’s designed to hold 1.6 billion gallons of water.
It’s still dry as dirt, but promises to be a central component of future water supplies for the 165,000 people served by the Santa Margarita Water District. While the district currently imports 100% of its drinking water from the Colorado River and northern California, the new Trampas Canyon Reservoir is part of a plan to generate 30% of potable water supplies locally and to recycle more wastewater.
California American Water and Marina city officials are in the process of setting up talks on the company’s desalination project after exchanging letters over the past several weeks. In a Sept. 25 letter, Cal Am president Rich Svindland reached out to Marina officials, proposing talks aimed at resolving differences over the company’s paused desalination project and suggested a series of “possible options that could be mutually beneficial for the city, Cal Am, and the region as a whole.”
Protecting intact peatlands and restoring degraded ones are crucial steps if the world is to counter climate change, European researchers said Friday. In a study, they said peat bogs, wetlands that contain large amounts of carbon in the form of decaying vegetation that has built up over centuries, could help the world achieve climate goals like the limit of 2 degrees Celsius of postindustrial warming that is part of the 2015 Paris agreement.
I got one of those calls again — they come every six months — from a Silicon Valley hotshot who wants to use his brain and his wealth to fix what ails California. This investor asked the same old question: What measures might I put on the ballot to reform the state’s politics and governance?
