Another Atmospheric River Storm to Hit Soaked California, Raising Fears of More Floods

An atmospheric river storm bearing down on California will drop more rain and snow this week, sparking fresh concerns about additional flooding and snowmelt in the already soaked state.

The storm, which originated near Hawaii, is expected to intensify Monday into Wednesday. It will create “considerable flooding impacts below 5,000 feet elevation across much of the California Coast and Central Valley and over the southern Sierra Nevada foothills,” the National Weather Service said.

Persistent Drought and Overdevelopment Cause Record Low Water Levels for Tens of Millions

Despite a rainy and snowy winter out west, Lake Powell and Lake Mead, the reservoirs that provide water for 40 million Americans, are at record low levels due to the ongoing megadrought. Arizona is set to lose over 20% of its Colorado River water allotment this year alone. As Stephanie Sy reports, that’s leaving communities across the state scrambling to find alternatives.

Atmospheric River-fueled Storm Arrives in California. Here’s Which Areas Will Be in the Bull’s-Eye

California is once again bearing the brunt of inclement weather, as a low-pressure system off the coast rapidly intensifies and becomes a storm, tapping into another atmospheric river that’s flowing between Hawaii and California.

The storm that started Monday night is forecast to raise powerful winds along the coast that will spread to all corners of the Bay Area, Central Coast and Central Valley and peak just before sunrise on Tuesday. These winds will ferry heavy rainfall, thunderstorms and the risk for more flooding across most of the California coast and eventually Southern California.

More Moisture is Headed to Utah, the West. Will It Help Lake Powell?

Lake Powell is currently close to 180 feet below full pool and coming off a summer last year where several boat ramps were closed and owners were advised to retrieve their houseboats from the docks.

Releases from a couple of upstream reservoirs, including Flaming Gorge, were made last summer to help the nation’s second largest reservoir and its Glen Canyon Dam, which provides power generation to Wyoming, Utah, Colorado, New Mexico, Arizona, Nevada and Nebraska.

EPA to Limit Toxic ‘Forever Chemicals’ in Drinking Water

The Environmental Protection Agency on Tuesday proposed the first federal limits on harmful “forever chemicals” in drinking water, a long-awaited protection the agency said will save thousands of lives and prevent serious illnesses, including cancer.

The plan would limit toxic PFAS chemicals to the lowest level that tests can detect. PFAS, or per- and polyfluorinated substances, are a group of compounds that are widespread, dangerous and expensive to remove from water. They don’t degrade in the environment and are linked to a broad range of health issues, including low birthweight and kidney cancer.

Newsom Loosens Rules to Allow More Floodwater to Flow Into Underground Reservoirs

As another round of heavy storms battered California, Gov. Gavin Newsom announced Friday that he would ease state rules to allow local water agencies to more easily redirect floodwaters to replenish the state’s severely depleted groundwater supplies.

The move comes amid criticism that California has flushed trillions of gallons of water out to sea during this winter’s repeated deluges. Water agencies and experts say the state’s strict rules that limit who can take water from streams and creeks have prohibited the local agencies from capturing the excessive flows, though California desperately needs to bank water for its next drought.

Battered by Destructive Flooding, California Braces for More Rain

California is bracing for another round of rain beginning Monday as officials assess the damage from severe flooding along the Central Coast and Central Valley, which left scores stranded, and whole blocks under water.

Sierra Snowpack Hits Record Levels After Recent Storms

The snowpack in the Sierra Nevada mountains has reached record-breaking levels thanks to the deluge of snow smashing California this week.

According to data from the California Department of Water Resources (CDWR), the Southern Sierras—from San Joaquin and Mono counties to Kern county—currently have a snowpack 257 percent greater than the average for this time of year, and 247 percent larger than is average for the usual snowpack peak on April 1.

An American Water Crisis

These are desperate days for the Colorado River.

The pulsing lifeblood of the U.S. southwest is increasingly parched. To avert catastrophe, the U.S. government will, within weeks, propose historic cuts in water access. It’s a frantic move to protect a river that provides so much: drinking water for tens of millions of people, electricity and food. Lots of food.

Opinion: The West’s Weather Whiplash Should Not Influence Long-Term Water Management

There’s a water contradiction in the West with serious long-term water scarcity in low reservoirs and depleting groundwater tables, while California is in the middle of an extremely wet and snowy winter. As water levels in dangerously depleted Lake Mead and Lake Powell drop to record lows, California has experienced one of the wettest winters on record, with a statewide snowpack that’s almost 200 percent of normal for this time of year and a flooding risks from rain and snow events in March.
