For much of the last 23 years, the Colorado River has been ravaged by unrelenting dryness, its reservoirs falling to their lowest levels since they were filled. New research shows that global warming is a major culprit, shrinking the river’s flow and robbing the region of a vast amount of water.
A team of scientists at UCLA estimated that from 2000 to 2021, rising temperatures led to the loss of about 32.5 million acre-feet of water in the Colorado River Basin, more than the entire storage capacity of Lake Mead, the country’s largest reservoir.

The drought-stricken Colorado River is in critical condition. Almost two years ago, the federal government declared the first ever shortage on the river, triggering cuts to water supplies in the Southwest. Today, the river remains unsustainably low. The Colorado is the lifeblood of the region. It waters some of the country’s fastest growing cities, nourishes some of our most fertile fields, and powers $1.4 trillion dollars in annual economic activity. The river runs more than 1,400 miles, from headwaters in the Rockies to its delta in northern Mexico where it ends in a trickle.

Free water use surveys offered through the Metropolitan Water District of Southern California provide both residential and commercial customers with recommendations to improve landscape and indoor water use efficiency. The surveys are available throughout Southern California, including San Diego County.
The San Marcos Unified School District took advantage of the opportunity for water use surveys at 17 of the district’s school sites. It is among the largest single regional customer survey to date.
Austin Black, water conservation specialist for WaterWise Consulting, oversees the audit project.
“We are auditing the irrigation system of all of the schools with more than one acre of landscape area [for this project],” said Austin. “The survey tests all the different irrigation zones, looking at the type of landscape and plant material, and weather factors. We take all that data and calculate potential water savings based on our recommendations.”
Recommendations may include converting to drip irrigation, installing smart controllers, and replacing grass with a WaterWise landscape with a more efficient watering system.

Surveyors also adjust existing sprinklers for maximum efficiency and compile a list of repairs and upgrades to improve water use efficiency.
“In our effort to be good stewards of all resources used by the district, the decision to participate was an easy one,” said Ted Norman, SMUSD executive director of maintenance and operations. “We will review all our options and implement as many of the recommendations as we can. It’s a win for everyone.”
Simple improvements add up to significant savings

In one example, the audit report provided to the district for the San Marcos Elementary School estimates that implementing the recommended water-saving measures can reduce landscape water use by approximately 252,000 gallons. Project cost savings are $1,363 annually. If similar savings are achieved at 17 schools, this reflects significant net savings to taxpayers.
“We will submit the reports, and the district can make the changes as they wish,” said Black. “The goal is to create water savings for the entire district and the [water] agency as well.”
MWD can assign a consultant to work with SMUSD and other customers after the audit is completed to help prioritize changes recommended in the survey. The consultant services are free.
Residential surveys find water, cost savings for homeowners

Homeowners can also take advantage of free surveys. Residential surveys look at both indoor and outdoor home water use.
“It’s a comprehensive survey checking for leaks and ways we can make the household more efficient,” said Black.
Along with irrigation improvements, the residential audit reviews the replacement of inefficient plumbing fixtures and other simple adjustments.
Customers of any of the San Diego County Water Authority’s 24 member agencies can visit the website waterefficiencysurvey.com. Enter home address to determine if your residence is located in a qualified area.

A certified landscape irrigation auditor will schedule a survey and provide written recommendations for qualifying properties. Participants will receive a written report that includes the following:
Data collected during the survey.
Recommendations for improving the site’s irrigation efficiency including system repairs, equipment updates, and irrigation scheduling.
Information about available financial incentives to help with the cost of recommended improvements.
Surveys are scheduled on a first-come, first-served basis. Applying does not guarantee a survey will be provided. Properties may only receive one survey for the life of the program. After filling out an online application the next step is scheduling a visit from a certified landscape auditor.
San Diego County residents can also take advantage of savings with rebates on a variety of water-saving technologies such as high-efficiency clothes washers and toilets, rain barrels and irrigation nozzles.

July has been so hot thus far that scientists calculate that this month will be the hottest globally on record and likely the warmest human civilization has seen, even though there are several days left to sweat through.
The World Meteorological Organization and the European Union’s Copernicus Climate Change Service on Thursday proclaimed July’s heat is beyond record-smashing.

Another week, another catastrophic, record-setting, history-making flood, this time in Kentucky.
Preliminary assessments indicate rainfall in Graves County last week likely set a new record for most precipitation in a 24-hour period, with 11.28 inches of rain. This would make it yet another “1,000-year” flood event, which had, according to historical projections, less than a 0.1 percent chance of occurring in any given year. One of the towns that experienced flash flooding was Mayfield, a community still rebuilding from a 2021 tornado that killed 57 people.
This was just one of the 11 flash flood emergencies in as many days in the United States, according to Weather Channel meteorologist Heather Zons. These events have claimed multiple lives: 2-year-old Mattie Shiels, 9-month-old brother, Conrad, and their mother, Katie Seley drowned after getting swept away by flash flooding in Pennsylvania, during an event that killed at least four others. In New York earlier this month, 43-year-old Pamela Nugent was swept away trying to evacuate a flooded area; 63-year-old Stephen Davoll drowned in his home in Vermont.

Helix Water District received recognition from The Climate Registry as a Water-Energy Leader Gold organization after the district reduced its electric use by 15% and greenhouse gas emissions by 40%.
The Climate Registry is a nonprofit organization that helps companies, governments, and institutions reduce their emissions. Its Water-Energy Nexus Registry is sponsored by the California Environmental Protection Agency and allows utilities and cities to measure, track, and mitigate greenhouse gas emissions associated with California’s water system.
The University of San Diego Energy Policy Initiative Center, or EPIC, confirmed the district’s 2019 and 2021 total greenhouse gas emissions are 40% lower than those in 2009. EPIC’s findings were verified by a third party. The Climate Registry made the announcement this month based on this verification.

“This award is a testament to the fact you can be a good steward of the environment while also making sound financial decisions,” said Helix Board President Kathleen Coates Hedberg. “We found that energy efficiency is very similar to water conservation. You take advantage of every opportunity to save a little bit because there isn’t one thing that will get you to the finish line. But together they have an impact.”
Retrofits, upgrades, and sustainability savings add up

Helix achieved its most recent emission reductions through multiple efforts, including a comprehensive lighting retrofit program, new lighting management system, and an upgrade to the HVAC system at the district’s R.M. Levy Water Treatment Plant.
Helix also transitioned its diesel fleet to 100% renewable diesel fuel.
Previously, the district installed solar panels at its operations center, initiated load shifting at its Levy Water Treatment Plant and pump stations to off-peak periods, and obtaining grants to install electric vehicle charging stations at its facilities.
In 2021, the San Diego County Water Authority earned Climate Registered gold status from The Climate Registry for verifying and publicly reporting its greenhouse gas emissions.
