You are now in California and the U.S. category.

West Likely to Be Stormier With Climate Change

The types of storms that have been bringing heavy snow and rain to the West this winter, triggering landslides and floods while easing stubborn droughts, are likely to become stronger and more frequent, according to the results of a conclusive new study.

The drenching storms have been falling from atmospheric rivers — high-altitude streams of moisture that carry much of the West’s water from the Pacific Ocean in sometimes-violent spurts that can lead to floods

California’s Water Supply at Risk From Warmer Winters

Any sign of precipitation in the forecast is a welcome sight for Californians these days. But with temperatures expected to be above normal this winter, California’s snowpack may not reach the heights it could.

Getting snow in the Sierra Nevada Mountains is crucial to the state’s water supply. But scientists say as the climate continues to warm, more precipitation will fall as rain instead of snow.

State Water Strategy: Crush the Little Guy

The water wars in California are getting uglier.
If you doubt that consider the plight of the Bryon-Bethany Irrigation District. They were slapped — along with other water districts — with a curtailment order on June 12 by the State Water Resources Control Board for water diversions based on pre-1914 appropriative water rights. The targeted districts including Byron-Bethany had the audacity to sue the state on June 26.
Two weeks later, Sacramento Superior County Court Judge Shelleycane Chang ruled the state orders constituted an invalid taking of property.

Many of California’s Larger Reservoirs Still Starved for Rain

With several Bay Area reservoirs nearly full, at capacity or overflowing, you might think we’re in good water shape.  But, when it comes to the state’s really big reservoirs, which we depend on most— think again.

Majestic Mount Shasta’s huge crown of snow gleams in the sun. Fifty miles south, Lake Shasta, California’s largest reservoir by far, is only just over half full; but better than it was in the fall.

As Drought Becomes the Norm, Where Can U.S. Turn for Lessons in Adaptation?

It’s official: the southwestern United States will likely never be the same again. A new analysis of the past 35 years of weather patterns concluded that what is now considered a normal year of rain and snow in the Southwest is one-quarter drier than it was before the 1970s.

And the climate conditions that bring the region most of its rain and snow will become even more rare in the future, according to a federally funded study posted online Thursday in the journal Geophysical Research Letters.

White House Proposes Millions for Big Water Innovations

Go ahead and turn up those Jock Jams, Obama, because your administration is doing something unprecedented before you become un-presidented: submitting a budget proposal with $267 million specifically devoted to water innovation.

OK, it’s more exciting than it sounds. The water tech section of the budget focuses on making desalination affordable, monitoring water use in real time, helping farmers grow food with less water, and forecasting floods and droughts with more precision, Fast Company reports.

The Great Wet Hope

While the Atlantic coast of America was preparing for last month’s massive snowstorm, California was enjoying a welcome, albeit temporary, reprieve from its four-year drought. The prolonged downpour—a harbinger of the imminent El Niño storms — raised pool levels in Los Angeles by almost three inches, providing your correspondent with an extra 500 gallons of water free of the city’s Tier 1 tariff.

Lawns, parks and hillsides that had been left to go brown during the drought (state-wide emergency measures have required cities to cut water usage by 25%) have turned green again. The one dismay has been seeing millions of gallons of precious rainwater pour down hillside gutters and storm drains, as it flowed unhindered into Santa Monica Bay.

Are Drought Conditions in the U.S. Southwest Here to Stay?

A new study suggests that dry conditions in the southwestern United States, including the ongoing California drought, may become standard.

The study, published in Geophysical Research Letters, analyzes weather types to demonstrate how the American Southwest has already shifted to a much drier climate system than it once had, along with showing a downward trend in overall precipitation. The research, which uses data from 1979 to 2014 collected from across the contiguous United States, could show that the dry pattern will continue into the future.

More Rain Coming; Catch It with Rain Barrels

So far, Southern California has not seen the back-to-back deluges highly anticipated with this year’s strong El Niño. Last Sunday’s storm dumped snow on the Sierra and thrashed Southern California with high winds, but Ventura County’s lower-lying communities got less than a half-inch of rain.

The county’s total rainfall to date this season is still below 60 percent of normal. But don’t lose confidence in El Niño yet. Curt Kaplan, a meteorologist in the National Weather Service’s Oxnard office, said, “We still have a very strong El Niño set up in the Pacific … and it’s still encouraging. We’ll see quite a few storms come through between now and the end of March and even April.”

Brown’s Projects Face Tests

The two immense public works projects that would be Jerry Brown legacies will soon face pivotal moments.

The years-long debates over a north-south bullet train and twin water tunnels beneath the Sacramento-San Joaquin Delta have focused on whether they are needed, as Brown contends, to enhance the state’s future.

Ultimately, however, whether they fly or die depends on securing tens of billions of dollars in financing.
