As trickling snowmelt in the Sierra Nevada slowly raises Mono Lake — famed for its bird life and outlandish shoreline mineral spires — advocates are pressuring state water officials to halt diversions from the lake’s tributaries to Los Angeles, which has used this clean mountain water source for decades.
The network of pipes and massive bathtubs that is the Colorado River Basin’s reservoir storage system is going to see some recovery this year thanks to higher-than-average snowpack. That’s a promising sign for aquatic habitats in need of a health boost.
Big crowds were out at Folsom Lake on Memorial Day, and with a record-breaking snowpack, the lake is now nearly full. But there’s also a large amount of water being released downstream
There’s now a plan underway to store more water in the lake, and that involves raising Folsom Dam.
This winter produced record snowfall in California, but a new study suggests the state should expect gradually declining snowpacks, even if punctuated with occasional epic snowfalls, in the future.
An analysis by Tamara Shulgina, Alexander Gershunov, and other climate scientists at UC San Diego’s Scripps Institution of Oceanography suggest that in the face of unabated global warming, the snowlines marking where rainfall turns to snow have been rising significantly over the past 70 years. Projections by the researchers suggest the trend will continue with snowlines rising hundreds of meters higher by the second half of this century.
At one of Los Angeles’s main water treatment plants a few miles north of the Port of Los Angeles, a small-scale facility is demonstrating what might be part of the solution to the region’s water woes. The Pure Water Southern California Demonstration Plant facility uses membrane bioreactors, reverse osmosis, and ultraviolet radiation to process about 500,000 gallons of treated wastewater a day, further purifying it into something clean enough to use in industry, replenish the region’s groundwater, and potentially put back into the city’s drinking water system.
During the El Niño of 1983, Californians counted their blessings. The warm Pacific waters sloshing eastward certainly brought heavy spring rains and record snow. But the state largely escaped the flood risks being frantically managed farther east.
Limiting the government’s authority to regulate wetlands under the Clean Water Act, the Supreme Court ended a nearly two-decade-old dispute Thursday.
The ruling from the court was unanimous, with the justices affirming summary judgment in the suit by Chantell and Michael Sackett against the Environmental Protection Agency.
This winter’s major storms laid down one of the largest snowpacks recorded in California’s Sierra Nevada, along with an unusual amount of snow at low mountain elevations.
But such prolific snowfall at lower elevations is set to become increasingly rare in coming years as climate change drives temperatures higher, according to new research.

A proposed deal for California, Arizona and Nevada to take less water from the over-tapped Colorado River depends heavily on $1.2 billion in federal funds, which will pay farmers and others who agree to give up some of their supply over the next three years.
