El Niño’s not done yet: Weeks of Dry Weather Ahead, But More Rain Expected after That

Water flows into Lake Oroville Tuesday from a pipe at the Nelson Bar Day Use Area. Although rainfall stopped with the coming of February, the lake continues to rise as snow in the mountains melts. The Department of Water Resources reports the lake has added almost 116,000 acre-feet in February, and the water level is up almost 17 feet, but the snowpack in the mountains above the lake is down from 122 percent of normal to 109 percent of normal in the same period.

Winter Brings Shift in Attitudes about Water

If there was one overriding theme to last year’s World Ag Expo it was water, with California farmers and ranchers clamoring to see the latest technology available to stretch the precious resource.

Soon after the gates opened Tuesday for this year’s show, a slight but noticeable change was apparent, as the booths selling irrigation equipment, filters, ground sensors and other irrigation-related products weren’t quite as busy as last year.

Judges Urge Mediation in Water Contract Fight

Calling an appeal between California environmentalists and federal agencies over expired water contracts a “bizarre position,” a Ninth Circuit panel Tuesday encouraged the parties to mediate the issue instead.

“This case is in a bizarre position – we’re dealing with 2012 contracts that have already expired, we’re told there are new ones with new environmental assessments,” Circuit Judge Barry Silverman said. “On top of all that we have Mother Nature playing tricks with the drought.”

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.
