In a startling development for California’s water system, state officials have confirmed the infestation of invasive golden mussels (Limnoperna fortunei) at two major Southern California lakes: Silverwood Lake in San Bernardino County and Pyramid Lake in Los Angeles County. The rapid spread of this highly destructive species from the Sacramento-San Joaquin Delta to the southern […]
A veteran water expert from Arizona says the Trump administration withdrew his nomination to lead the federal agency that oversees water management in the western U.S., leaving the Bureau of Reclamation without permanent leadership this year. Ted Cooke told The Associated Press late Wednesday that he was preparing for a Senate confirmation hearing early this month but […]
The Trump administration says it will defend a Biden era-rule that is expected to keep polluters on the hook to clean up toxic “forever chemicals.” The rule in question designated two types of these chemicals as “hazardous substances,” giving the Environmental Protection Agency (EPA) more authority to clean up their contamination and require polluters to pay for it.
A new report from Colorado River researchers found water levels at the nation’s two largest reservoirs are dropping fast and on track for dire consequences. The authors are calling on policymakers to move with urgency and protect Lake Powell and Lake Mead. Negotiators are locked in talks about the future of those reservoirs after 2026, […]
California was supposed to kick off a new era of dam building when voters passed a $7.5 billion water bond in 2014. But ten years later, only one dam project from the list is still alive. Sites, which would divert water from the Sacramento River into an offstream reservoir capable of storing water for 3 […]
Adding new snowpack monitoring stations at strategic locations would be better at predicting water supply in the western U.S. than basin-wide mapping — and it would be less expensive — according to a new study. “Measuring snow in the right places can benefit forecasts more than measuring it everywhere,” said lead author Mark Raleigh, an […]
