The California water wars of the early twentieth century are summed up in a famous line from the 1974 film Chinatown: “Either you bring the water to L.A., or you bring L.A. to the water.” Nearly a hundred years have elapsed since the events the film dramatizes, but much of the West still approaches water the same way. If you don’t have enough of it, go find more.
As politicians across the West confront the consequences of the climate-fueled Millennium Drought, many of them are heeding the words of Chinatown and trying to bring in outside water through massive capital projects. There are at least half a dozen major water pipeline projects under consideration throughout the region, ranging from ambitious to outlandish. Arizona lawmakers want to build a pipeline from the Mississippi River more than a thousand miles away, a Colorado rancher wants to pipe water 300 miles across the Rockies, and Utah wants to pump even more water out of the already-depleted Lake Powell.

As summer begins to wind down, the dry weather that has plagued California this year continues, leading to a number of new drought-related issues.
Over the course of the past 30 days, 11 new dry well reports in Butte County have been sent to the California Department of Water Resources. That comes out to 39 in the past year and 98 total.
Additionally, Glenn County has seen 105 total dry well reports and Tehama County has reported 229, according to data from DWR.

Erin Brockovich made her name decades ago as an environmental activist who exposed corporate wrongdoing that polluted drinking water.
So she felt a bit defensive when a television reporter asked how her name landed on a list of water guzzlers during a dire California drought. At one point last year, she received a $1,700 bill for two months of water and fines.
Ms. Brockovich ultimately decided she had to get rid of her lawn, a central part of the backyard oasis she had built over more than two decades living in Agoura Hills, a suburb of large homes with immaculate yards about 40 miles northwest of downtown Los Angeles. She replaced 3,100 square feet of grass with high-tech artificial turf.

A team led by Kristen Guirguis, a climate researcher at Scripps Institution of Oceanography at UC San Diego, found evidence that the risk of hazardous weather is increasing in the Southwest.
The researchers investigated the daily relationships among four major modes of weather affecting California. How they interact governs the formation of weather events such as atmospheric rivers capable of bringing torrential rains and Santa Ana winds that can spread devastating wildfires.
“This study suggests that weather patterns are changing in a way that enhances hot, dry Santa Ana winds, while reducing precipitation frequency in the Southwest,” said Guirguis. “These changes in atmospheric circulation are raising the risk of wildfires during California winters.”

The basis of the research was an examination of the dominant atmospheric circulation patterns over the North Pacific Ocean, known as Baja-Pacific, Alaskan-Pacific, Canadian-Pacific, and Offshore-California modes. What distinguishes them from each other are the relative positions of ridges and troughs in the atmosphere.
Weather patterns and a warmer atmosphere
The research team identified 16 recurring weather patterns that are created daily as these modes interact with each other. One product of the work was a summary of California weather patterns from 1949 to 2017. The patterns associated with the formation of dry gusty Santa Ana winds that often stoke Southern California fires are becoming more frequent. Patterns associated with what might be considered “normal” rainfall are decreasing in the Southwest thus promoting drought, but patterns associated with extreme precipitation and strong atmospheric river episodes have remained steady over the study period. The researchers noted that while the patterns associated with heavy precipitation and strong atmospheric rivers have not changed in frequency, a warmer atmosphere is capable of holding more water so these storms are becoming more damaging.
Challenges for wildfire and water resource management
The results suggest an increasing probability of compounding environmental hazards during California winters, said the research team. Though winter atmospheric rivers are the antithesis of hot, dry Santa Ana wind conditions, sequences of wildfires followed by strong atmospheric rivers often compound the damage from fires when they trigger flash floods and destructive debris flows from burn scars.

“This spells challenges for wildfire and water resource management and provides observational support to our previous results projecting that California will increasingly have to depend on potentially hazardous atmospheric rivers and floodwater for water resource generation in a warming climate,” said study co-author Alexander Gershunov, a Scripps Oceanography climate scientist.
Study authors say this work is helping to inform an experimental subseasonal-to-seasonal (S2S) forecast product being developed at Scripps Oceanography’s Center for Western Weather and Water Extremes (CW3E) that predicts extreme weather in California including atmospheric river landfalls, Santa Ana winds, drought, and heat waves.
The U.S. Department of the Interior via the Bureau of Reclamation and the Southwest Climate Adaptation Science Center, the California Department of Water Resources, and the Regional Integrated Sciences and Assessments (RISA) California—Nevada Climate Applications Program and the International Research Applications Program of the National Oceanic and Atmospheric Administration funded the study. Additional funding was provided by the University of California Office of the President MRPI grant.

It’s a picture-perfect day in Southern California. The sun is beating down on this Carlsbad beach, where volleyballs hit the sand and surfers paddle out into the waves. Just steps from here, the salty water lapping the shore is being transformed.
This beach neighbors the largest desalination facility in the Western Hemisphere. The Carlsbad Desalination Plant uses a complex web of pipes, tanks and specialized filters to pull salt and impurities out of ocean water, turning it into part of the drinking supply for San Diego County.
Water managers are feeling the crunch of a supply-demand imbalance along the Colorado River. Fresh water reserves are shrinking as climate change squeezes the river that supplies 40 million people and fields of crops across seven states. Some have proposed desalination technology as a way to augment that supply, easing the strain on a river that supplies a growing population from Wyoming to Mexico. Experts say it could be part of the solution, but likely won’t make much of a dent in the region’s water crisis.
At the Carlsbad plant, former seawater poured into a cup from a freshwater spigot. Michelle Peters, technical and compliance manager for plant operator Poseidon Water, held it and took a drink.
“At 10 a.m, the morning surfers were swimming in it off the coast in the ocean here,” she said. “Now it’s high-quality drinking water, ready for consumption.”

San Diegans get more than half their water from the Colorado River. So why haven’t local leaders rung alarm bells as Lake Mead has shrunk to record-low levels?

As the current drought stretches into a third year, the San Diego County Water Authority is providing water saving tips as part of a drought survival kit to San Diegans.
Scientists confirm California and the Southwest U.S. is experiencing the worst megadrought in the last 1,200 years. It has prompted Governor Gavin Newsom to order new emergency water rules and cutbacks with the goal of preparing the state for a 10% decrease in the available water supply by 2040.
“The hots are getting a lot hotter, the dries are getting a lot drier and … the wets are getting wetter,” Newsom said in announcing the plan at a desalination plant under construction in Antioch, 45 miles inland from San Francisco, that will turn brackish water into drinking water.
Without action, extreme weather could diminish our water supply by up to 10% by 2040. So we’re acting now.

Water saving tips
Many years ago, San Diego regional water leaders had the foresight to call for conservation efforts to help build our resilience. Now we are in a more fortunate position thanks to our diversified water supply than much of the state.
San Diegans have learned how to conserve water, but there is always more we can do. San Diego County Water Authority Water Resources Specialist Efren Lopez joined CBS 8 Anchor and Reporter Carlo Cecchetto on the news program “The Four” to discuss the Governor’s report and offer additional ways San Diegans can reduce water use.
Water conservation is a way of life
“San Diego’s great at conservation. Conservation is a way of life here, but there is always something more we can do,” said Lopez. He suggests homeowners use a shutoff nozzle when hand watering using their garden hose and test soil with a moisture sensor to determine when soil is dry enough before irrigating.
In addition to water-saving measures, San Diego County residents can take advantage of the Water Authority’s rebate programs for turf replacement, irrigation devices, and WaterSmart landscape gardens. Countywide, San Diegans have removed more than one million square feet of turf through rebate programs, resulting in annual water savings of 36.5 million gallons.
“In San Diego, we’ve been diversifying our water supply for decades,” said Lopez. “So we’re prepared for this drought. It’s great to see the governor supportive of resilient supplies and a portfolio approach to our water supply so that we don’t rely on just one source.”
Lopez encouraged San Diego County residents to get additional tips for saving water at www.watersmartSD.org.

California Governor Gavin Newsom unveiled a new water strategy on Thursday that plans for a future with 10% less water and shifts the emphasis from conservation to capturing more water that otherwise flows out to sea.
Climate change has contributed to more severe drought but has also set the stage for more intense flooding when rain does fall, as was demonstrated last week in California’s Death Valley, one of the hottest, driest parts of the United States.
Following Governor Gavin Newsom’s recent executive order and a State Water Board emergency regulation, members of the California Urban Water Agencies, or CUWA, including the San Diego County Water Authority continue to advance water-saving efforts, yielding measurable results. These efforts come on the back of the driest first quarter in California’s history, which prompted the Governor to call for local water conservation steps rather than a one-size-fits-all approach.
