On June 10, the city of San Diego implemented more stringent restrictions for all water customers, following a statewide order to conserve throughout California. We are calling on San Diegans to cut back their usage, not just because it’s the prudent thing to, but also to avoid more drastic measures that could come in the near future if we don’t take these new restrictions to heart.
As the unprecedented drought continues to affect California and the San Diego region, homeowners can still balance the need to conserve water as efficiently as possible while preserving valuable landscaping, including trees. Trees can be maintained while following California’s water guidelines.
As the unprecedented drought continues to affect California and the San Diego region, homeowners can still balance the need to conserve water as efficiently as possible while preserving valuable landscaping, including trees.
Trees can be maintained while following California’s water guidelines. Trees are among the most valuable investment in San Diego County’s landscape – including your own WaterSmart landscaping. No other landscape plant offers more significant benefits to your landscape and the environment. Trees provide much-needed shade and cooling to increasingly hot neighborhoods and cities and are among the most efficient natural ways to remove harmful carbon dioxide fueling global warming.
When mature trees die due to lack of irrigation, they become a dangerous fire hazard. They are expensive to remove. Young replacement trees take many years to provide the benefits of mature trees. Taking care of your trees during drought ensures a tremendous return on this investment.
Even when not in an acute drought, trees planted in a Mediterranean climate often need some additional water. Mimic the way Mother Nature provides water for the most effective irrigation.
Healthy tree roots reach three to four feet deep at the outer edge of a tree’s branches, where rainfall would naturally run off leaves. This area at the edge of the tree canopy is called the drip line.
When it does rain, Mother Nature’s rainfall is primarily steady, slow, and spread out. Follow this method to deliver a prolonged, slow soaking. Trees prefer infrequent deep watering. During drought, slow watering every two or three weeks for more established trees is sufficient. Avoid runoff with multiple cycles to allow water to soak deeply. Irrigate early in the morning to minimize evaporation.
Keep in mind turf competes with your trees for water. Even if you want to retain some lawn, it’s smart to remove the lawn immediately around your trees and replace it with WaterSmart landscaping.

Drought is a reality in the San Diego region as average temperatures increase. As summer months become hotter, soils dry out. Trees must be deep watered to supply their roots and preserve their health.
San Diego forestry and landscaping professionals are working with the San Diego County Water Authority and its 24 member agencies to help protect our region’s trees while also conserving water. Find more resources and learn more at drought.katestrees.org.

San Diegans on Tuesday continued to avoid any immediate repercussions from the 22-year megadrought that has ravaged the Colorado River, threatening the water supply of 40 million people across the American West. The region gets more than half its water from the river through a 2003 deal with farmers in the Imperial Valley, which has so far proved a prescient, albeit costly maneuver.
For the second year in a row, Arizona and Nevada will face cuts in the amount of water they can draw from the Colorado River as the West endures more drought, federal officials announced Tuesday.
Though the cuts will not result in any immediate new restrictions — like banning lawn watering or car washing — they signal that unpopular decisions about how to reduce consumption are on the horizon, including whether to prioritize growing cities or agricultural areas. Mexico will also face cuts.
Aug. 16, 2022 – Sandra L. Kerl, general manager of the San Diego County Water Authority, issued the following statement in response to the U.S. Bureau of Reclamation’s 24-month projection for water levels in Lake Mead and Lake Powell.
“Today’s announcement by the Bureau of Reclamation is a reminder of just how important it is to increase water conservation across San Diego County and the rest of the arid West. An increasingly hot and dry climate is creating unprecedented challenges for water supplies that will impact life in the Southwest for the foreseeable future.
“The San Diego County Water Authority continues to participate in discussions about the future of the Colorado River. We also continue to highlight the value of the conserved water transfer agreement between the Water Authority and the Imperial Irrigation District, the cornerstone of the landmark Quantification Settlement Agreement, or QSA, negotiated in 2003, as well as our investments in concrete lining sections of the All-American and Coachella Canals to conserve water previously lost to seepage. Through the QSA, the Water Authority funds critical conservation efforts in the Imperial Valley that provide the San Diego County region 277,700 acre-feet of highly reliable, cost-effective conserved water supplies each year. Further, the QSA enables California to live within its historic 4.4-million-acre-foot annual Colorado River apportionment while providing a roadmap for current efforts to balance the complex economic, agriculture, environmental, most notably the Salton Sea, and water-use needs in the Colorado River Basin.
“The Water Authority has not been asked to make any voluntary reductions to Colorado River water supplied by IID under Reclamation’s call for additional basin-wide conservation. If cuts were deemed mandatory to IID through an official Secretarial declared shortage to Priority 3 water in California, the Water Authority would take a pro-rata reduction of its IID transfer supplies.
“Investments by San Diego County residents in other water sources and storage facilities will continue to shield the region from the worst effects of the drought. At the same time, the potential for mandated water-use reductions should inspire every San Diegan to decrease their water use, for instance, by taking shorter showers, reducing irrigation of decorative grass, and upgrading to efficient appliances.”

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. San Diegans have learned how to conserve water, but there is always more we can do. Water Authority Water Resources Specialist Efren Lopez joined CBS 8 Anchor/Reporter Carlo Cecchetto on the news program “The Four” to discuss Gov. Newsom’s new water portfolio strategy and offer additional ways San Diegans can reduce water use.
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.”
