Clean Energy Alliance Approves MOU That Would Include Service to Carlsbad Desalination Plant

The Clean Energy Alliance Board of Directors approved a memorandum of understanding on July 27 that would bring the largest consumer of electricity within Carlsbad into the fold. The San Diego County Water Authority and Channelside, the company that owns the Carlsbad Desalination Plant, have an agreement that allows the water authority decision-making power on an electricity provider, according to a CEA staff report. The MOU, which is pending final approval later this year, would make the Clean Energy Alliance that provider.

California’s Winter Waves May Be Increasing Under Climate Change

A new study from UC San Diego Scripps Institution of Oceanography researcher emeritus Peter Bromirski uses nearly a century of data to show that the average heights of winter waves along the California coast have increased as climate change has heated up the planet.

Repairs Underway on Mexican Wastewater Pipe as Coronado’s Water Bacteria Levels Rise Again

The Coronado and Silver Strand shorelines are under advisory again after water bacteria levels exceeded state standards over the weekend as projects to address the Tijuana sewage crisis trudge forward on both sides of the border. In Mexico, a ruptured 42-inch wastewater pipe is expected to be repaired by November. It ruptured last summer, adding to the flow of untreated wastewater from Tijuana into coastal waters and across the U.S.-Mexico border.

Colorado River Task Force Focuses First Meeting on Hopes, Concerns about Fast-Paced Process

Members of the Colorado River Drought Task Force met for the first time Monday to lay the groundwork for five months of water supply problem-solving. The Colorado General Assembly passed legislation in May to create the interim task force, which will study and recommend ways state lawmakers can address Colorado River water scarcity in the future. As the members head into those discussions, several of them said one of their main priorities is to condense diverse and at times conflicting perspectives into a unified message for lawmakers.

Los Angeles DWP Loosens Watering Rules to Three Days a Week, Citing Wet Winter

More than a year after instituting the strictest water conservation orders Los Angeles has ever seen, the L.A. Department of Water and Power announced Monday that it was loosening watering rules for its 4 million customers. Effective immediately, all Angelenos can return to three-day-a-week watering schedules after being placed on two-day-a-week limits in June 2022, the agency said.

San Marcos Unified School District Benefits From Free Water Use Survey

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.

Colorado River Losing Vast Amounts of Water Due to Warming Climate, Study Finds

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.

July Keeps Sizzling as Phoenix Hits Another 110-Degree Day and Wildfires Spread in California

Phoenix sizzled through its 31st consecutive day of at least 110 degrees Fahrenheit (43.3 Celsius) and other parts of the country grappled Sunday with record temperatures after a week that saw significant portions of the U.S. population subject to extreme heat.

The National Weather Service said Phoenix climbed to a high of 111 F (43.8 Celsius) before the day was through.

Opinion: Arizona Has an Ambitious Goal to Save Water – If We Can Pull it Off

Five years from now, if all goes to plan, Arizona will have conserved 5 million acre-feet of water.

That’s enough to fill about 2.5 million Olympic-sized swimming pools.

Or about 70% of what the state is estimated to use in a year, from all sources.

Or a little less than double Arizona’s annual Colorado River allotment (that is, if we were getting our full allocation, which hasn’t happened in a while).

Southwest States Facing Tough Choices About Water as Colorado River Diminishes

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.
