California is Working on Solutions to Worsening Climate Change. Will They Be Enough?

/in , , /by /Los Angeles Timesby Dorany Pineda

In the opening chapter of “The Ministry for the Future,” science-fiction author Kim Stanley Robinson details a calamitous heat wave that kills almost all the residents of a small town. In another chapter, he imagines a catastrophic flood that wipes out Los Angeles.

The late Octavia Butler described a Southern California reeling from years of drought in “Parable of the Sower,” and Paolo Bacigalupi writes about a near-future Southwest that’s also been devastated by drought.

The arrival of Tropical Storm Hilary in the region on Sunday was an ordeal or a huge inconvenience for many people — especially those who struggled with flooding in Tijuana, air travelers dealing with flight cancellations and delays, and drivers using Interstate 8 who only learned the freeway was closed in the Ocotillo area when they came upon massive lines of cars and 18-wheelers.

Vista Irrigation District Celebrates 100 Years of Service

/in , /by

The Vista Irrigation District, one of the San Diego County Water Authority’s 24 member agencies, is celebrating its 100th anniversary.

In the 1920s, citrus and avocado farming in the Vista area increased so quickly that the growing region faced the real danger of running out of water. Completing the Henshaw Dam in 1923 made it possible for the Vista community to receive a reliable water source instead of relying on well water.

The arrival of the new water source sparked discussion about forming a water district to secure additional imported water to make continued growth possible. On August 28, 1923, voters approved the formation of the Vista Irrigation District (VID) in a landslide: 104 votes to four votes in a 100% voter turnout.

337 customers then, 134,000 customers now

In its first year, VID served 337 customers. Today, VID serves water to more than 134,000 customers in a diversified community and robust economy and is celebrating its 100th anniversary on August 28, 2023.

“Vista Irrigation District is proud of its accomplishments over the last century and looks forward to providing reliable water service to the residents and businesses it serves for years to come,” said Board President Jo MacKenzie.

Water builds new potential in Vista

The Vista community celebrated the arrival of the first water from Lake Henshaw on February 27, 1926. Following the arrival of water, crops of all kinds were planted in increasing numbers. The Vista area became known as the “Avocado Capital of the World,” with six avocado packing houses in the area.

In June 1946, after several years of negotiations, Vista Irrigation District purchased the San Diego County Water Company. Included in the purchase was the 43,000-acre Warner Ranch, a former Spanish Land Grant, which includes Henshaw Dam and Lake Henshaw. The deal was driven by the economic motivation to find another, less costly source of water for VID’s customers.

Drought conditions and population growth continued to press VID to seek additional sources of water. On February 16, 1954, the Vista Irrigation District became a member of the San Diego County Water Authority. It allowed VID to bring in water imported from the Colorado River and Northern California.

One year later, in 1955, Vista’s first suburban-style housing arrived in what had been an agricultural community. The Vista area began experiencing a decline in its avocado producing and packing due primarily to the industry’s economic decline and drought, which would continue into the 1960s. Many avocado groves were split into smaller parcels and sold to housing developers. The land was more valuable for homes.

A century of success

The people’s vote in 1923 revolutionized the small rural settlement held back by a lack of water. Over the years, Vista transformed itself from its agricultural origins to a thriving community with a diversified economic base and a revitalized downtown.

Vista Irrigation District has demonstrated its ability to adapt to these ever-changing landscapes over time and looks forward to many more successful years of service to the community. Through a century of service and stewardship, the Vista Irrigation District can take credit for its solid track record over the last century to continue many more successful years of service to the community.

(Editor’s note: The Vista Irrigation District is one of the San Diego County Water Authority’s 24 member agencies that deliver water across the metropolitan San Diego region. The District is celebrating “A Century of Service and Stewardship” on Saturday, September 9, at its Vista headquarters. The public is invited to attend.)

Southern California’s ‘Water Doctor’ Pushes for Transformation to Adapt to Climate Change

When Adel Hagekhalil speaks about the future of water in Southern California, he often starts by mentioning the three conduits the region depends on to bring water from hundreds of miles away: the Los Angeles Aqueduct, the Colorado River Aqueduct and the California Aqueduct.

Multiyear El Niño and La Niña Events Likely to Increase, Researchers Say

/in , , /by /Courthouse News Service by Alanna Madden

Climate scientists are bracing for potentially lengthy El Niño and La Niña events, according to a new study revealing how the underlying mechanism for climate variability is responding to increased greenhouse gas emissions in unpredicted ways and inducing El Niño-like conditions after volcanic eruptions.

The research published in Nature Wednesday details recently discovered trends of the “Pacific Walker Circulation,” (PWC) an atmospheric phenomenon relating to east-west circulation along the equatorial Pacific.

Post-Tropical Storm Hilary Pushes into Nevada After Drenching Southern California

/in , , /by /AP Newsby Christopher Weber, Damian Dovarganes and Jordi Lebrija

Tropical Storm Hilary drenched Southern California from the coast to the desert resort city of Palm Springs and inland mountains, forcing rescuers to pull several people from swollen rivers.

By early Monday, remnants of the storm that first brought soaking rains to Mexico’s arid Baja California peninsula and the border city of Tijuana, threatened Nevada and as far north as Oregon and Idaho with flooding.

Southern Californians were battling flooded roads, mudslides and downed trees.

Opinion: Climate Change Will Undermine Quest by Fallbrook and Rainbow for Cheaper Water

/in , , /by /Water News Network / Times of San Diegoby Chris Jennewein Mentioned: San Diego County Water Authority

The long-running debate over whether the Fallbrook and Rainbow communities should leave the San Diego County Water Authority to obtain cheaper rates ignores a very large elephant in the room — climate change.

If the two rural communities cast their lot with Riverside County, their agricultural economy will depend upon the Colorado River and the State Water Project, both of which have been reeling from increasingly severe droughts.

How Climate Change Shaped California’s First Tropical Storm in Decades

/in , , /by /E&E Newsby Chelsea Harvey

Tropical Storm Hilary made history Thursday, becoming the first storm of its kind to enter California since 1997. The state rarely sees landfalling tropical cyclones or hurricanes, thanks to a confluence of cold water and unfavorable atmospheric conditions off the coast. Experts say the occurrence will likely remain relatively rare even as the climate changes. But rising ocean temperatures mean the hurricanes that do happen to make it up the coast may be stronger and more damaging.

Opinion: Climate Change Will Undermine Quest by Fallbrook and Rainbow for Cheaper Water

/in , /by /Times of San Diego by Chris Jennewein

The long-running debate over whether the Fallbrook and Rainbow communities should leave the San Diego County Water Authority to obtain cheaper rates ignores a very large elephant in the room — climate change.

If the two rural communities cast their lot with Riverside County, their agricultural economy will depend upon the Colorado River and the State Water Project, both of which have been reeling from increasingly severe droughts.

In December, just six months before the two communities’ case was heard by the Local Agency Formation Commission, the State Water Project announced that for the second year in a row, it would provide only 5% of requested water allocations.

Unexpectedly heavy winter rains then saved California, but not the Colorado River basin, where Lake Mead, the nation’s largest reservoir, remains 165 feet below its historic full level.

In May, the Western states that tap the Colorado River agreed to a reductions of up to 30% in water allocations. That’s a lot, and it’s not clear it is enough to save Lake Mead in the long run.

So Fallbrook and Rainbow are taking a risk. It’s a risk that was noted, albeit only briefly and obliquely, in the LAFCO proceedings.

“The superior reliability of SDCWA’s supply has benefitted FPUD and RMWD in the past … In switching from being wholesale customers of SDCWA to EMWD, FPUD and especially RMWD may face some challenges,” according to the official report for LAFCO.

Those “challenges” during a future drought could be a major reduction in water supply and higher prices at a time when the rest of San Diego County, thanks to the desalination plant, water recycling and the giant San Vicente Reservoir, has plenty of water.

Fallbrook and Rainbow say they don’t really benefit from this reliability, since their water systems are not directly connected. But water is a fungible resource. The two districts do have direct access to Colorado River water earmarked for San Diego County.

If the rest of San Diego County needs less Colorado water because of the investment in local supplies, then that water can be diverted to Fallbrook and Rainbow during a drought. And that’s exactly what happened during the most recent one. In any case, the Water Authority has plans for a physical connection, though it backed off amid the dispute.

Climate change impacts

There’s a whiff of national politics in all this. These are conservative communities where some may doubt climate change, and local business leaders have criticized desalination as a boondoggle. If you sincerely do not believe the climate is changing, then maybe you don’t see a risk in changing water suppliers.

In many ways this controversy is a bellwether for future wrangles over resources amid climate change. Do we stick with the old ways — in this case tapping our lakes and rivers — and hope for the best, or do we continue to invest in alternatives to protect our future?

It’s expensive to build desalination plants, recycling projects and new reservoirs, just like it’s expensive to upgrade the electrical grid and install car chargers. But a changing climate doesn’t ask for permission to impact our lives.
