The years-long drought and dwindling water supply are estimated to have left more than 531,000 acres of California farmlands unplanted without harvest this year — a 36% increase since August of last year.
The new estimates on acres farmed from the U.S. Department of Agriculture (USDA) reflect the struggles of some California farmers to procure water to irrigate their crops as major government water projects supplying their water remain thirsty as drought continues for a third year.
Sen. Catherine Cortez Masto joined state water officials Monday to demand immediate federal action on the Colorado River water crisis as Nevada faces its second year of mandatory water cuts.
Last week, federal officials announced that Nevada would lose about 8% of its water allocation, or 25,000 acre-feet of water, starting January 2023 as a stopgap solution to stabilize water levels at Lake Mead.
“The shadows sway and seem to say/ ‘Tonight we pray for water, cool water’/ And way up there He’ll hear our prayer/ And show us where there’s water, cool, clear, water.” Sons of the Pioneers, singing Bob Nolan’s “Cool Water” in 1941.
Eighty-one years later, the “show us where there’s water” prayer remains.
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.
The Colorado River is the backbone of the West’s water supply. The river provides water to hundreds of thousands of acres of farmland and 40 million people in seven U.S. states (California, Colorado, Wyoming, Utah, New Mexico, Arizona and Nevada) and northern Mexico. But overuse, a 23-year “megadrought” and aridification fueled by the climate crisis has left the river stretched far too thin.
Federal officials aren’t ready to give states along the Colorado River a new deadline for water conservation goals.
The seven states that rely on the river blew past an August 16 deadline without a plan to conserve 2 to 4 million acre-feet of water. They were given that task by officials with the Bureau of Reclamation and from within the Interior Department. The agency’s models show that amount is what is necessary to keep the river’s biggest reservoirs — lakes Mead and Powell — from reaching critical levels.
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.

The Vista Irrigation District Board of Directors recognized Jennifer Dell as its 2022 WaterSmart Landscape Contest winner for her creative, colorful use of materials and plants. The annual contest recognizes outstanding water-wise residential landscapes based on overall attractiveness, appropriate plant selection, design, appropriate maintenance, and efficient methods of irrigation.
San Diego County is not currently facing water cuts as the historic drought reaches a new low and the nation’s largest reservoir — Lake Mead — is at its lowest water level on record, according to the San Diego County Water Authority.
