Californians could be drinking water tapped from the Pacific Ocean off Malibu several years from now — that is, if a company’s new desalination technology proves viable. OceanWell Co. plans to anchor about two dozen 40-foot-long devices, called pods, to the seafloor several miles offshore and use them to take in saltwater and pump purified fresh water to shore in a pipeline.
California has long struggled with chronic drought and water scarcity—Newsweek spoke to two experts about whether capturing water from fog may be able to help. They were both optimistic about using fog harvesting for California, which is being explored there with several research initiatives and pilot projects, but warned that it probably “can’t produce water for all of the needs and demands of humans and society.”
A new report released on March 13, 2025, shows that changes to reservoir operations at Lake Oroville and New Bullards Bar Reservoir in California can further reduce flood risk for communities along the Tuba and Feather rivers during extreme atmospheric river storm events and potentially benefit water supply during drier river periods.
The recent rain and snow are much needed for Central California’s water supply.
The latest set of storms is already sparking talk of a “Miracle March.”

Eyewitness News was given a rare look inside the engineering marvel, which was the largest public works project in Southern California during the Great Depression, while it’s shut down for its annual maintenance. It’s the final leg of the massive Colorado River Aqueduct: the 13-mile-long San Jacinto tunnel, bringing up to 1,700 cubic feet of water per second underneath one of Southern California’s tallest mountains.
U.S. Environmental Protection Agency (EPA) Administrator Lee Zeldin announced last week that EPA will work with the United States Army Corps of Engineers to review the definition of “waters of the United States.” EPA said it will move quickly to ensure that a revised definition follows the law, reduces red-tape, cuts overall permitting costs, and lowers the cost of doing business in communities across the country while protecting the nation’s navigable waters from pollution.
Representatives of California, Arizona and Nevada are urging the Trump administration to take a different approach in confronting the problems of the water-starved Colorado River. As Trump’s appointees inherit the task of writing new rules for dealing with the river’s chronic water shortages, the three states are raising several concerns they want to see addressed.
The Trump administration announced a wave of regulatory rollbacks on Wednesday including a repeal of Biden-era emissions limits on power plants and automobiles, as well as reduced protections for waterways.
