California Heat Wave Sending Record Snow Melt Surging Into Rivers

The heat wave is melting snow in the Sierra, which is bringing freezing cold water into the valley’s lakes, streams and rivers. The effects of the snowmelt can also be deadly and proved so on Tuesday. “With this fast moving water it does not take long for someone to get in trouble,” said State Parks Ranger Scott Liske. Liske says a group of friends from Sacramento was swimming in the main channel of the North Fork when one of them drowned.

NASA Looks to Future When Snowpack Can Be Measured without a Pole

Every year for almost half a century, California snow surveyor Pat Armstrong has trekked the rugged Sierra Nevada with three simple tools: a snow core tube, a scale and a notebook. For as long as he can remember, state water officials have relied on the accuracy of those tools to deliver crucial data on the size of the Sierra snowpack and its ability to sustain a growing population. “It hasn’t changed in a hundred years,” Armstrong said of the survey.

Signs of Past California ‘Mega-Quakes’ Show Danger of the Big One on San Andreas Fault

The pass is best known for the spinning wind turbines that line it. But for geologists, the narrow desert canyon is something of a canary in the coal mine for what they expect will be a major earthquake coming from the San Andreas Fault. The pass sits at a key geological point, separating the low desert from the Inland Empire, and, beyond that, the Los Angeles Basin. Through it runs an essential aqueduct that feeds Southern California water from the Colorado River as well as vital transportation links. It’s also the path for crucial power transmission lines.

Bill Aims to Help California Save Water for a Not-So-Rainy Day

After years of drought, the state of California is bracing for water. Lots of it. Maybe even a rerun of the havoc caused by the failure of the Oroville Dam this winter. As the record snows in the Sierra Nevada mountains begin to melt, there’s concern this spring and summer that the state will have more water than it can handle. Earlier this year, heavy winter rains forced evacuations near the Oroville Dam, where repairs are now underway on the damaged flood-control spillway.

It Was 127 Degrees in Death Valley, and Miserable Just About Everywhere Else. Here’s How We Coped

In Death Valley, the heat brought even the roadrunners to a stop. They stood arched to the sky with their beaks wide open, as if in a stupor, or indignant at what the sun was up to. The landscape blurred and undulated. People moved as if they were walking through glue. When a light breeze came in the afternoon, it stung their faces so badly they had to turn away from it. Water mains burst in the baking dirt, while the “cold” tap water came out of faucets the temperature of a Jacuzzi.

BLOG: More Confusion Than Clarity In Tunnels EIR

The final version of Gov. Jerry Brown’s twin tunnels plan is better than earlier drafts but still contains “key flaws,” independent scientists say, including an environmental impact report that is so chock full of facts that it doesn’t tell a clear story. The latest draft critique marks the Independent Science Board’s fifth review of various iterations of the tunnels plan. Their criticism isn’t really about the tunnels themselves, but rather the documents that are being used to justify their construction.

 

 

Parched By Drought, Lake Mead Levels Could Lead To Water Limits Across AZ

Arizona risks losing water rights because of a lingering, nearly two-decade long drought in the Colorado River that could restrict water use ranging from farmers’ crops to how many households receive water, state water experts say. Calcium rings around Lake Mead tell the story of declining water levels, with cream markings permanently decorating the canyon walls that shows high levels that haven’t been seen since 1983. Current surface elevation is at 1,081 feet. If it drops another six feet, water to Arizona will likely be cut, according to an Arizona budget document.

Heat Wave Accelerating Runoff From Sierra

Heavy rains and snowthis past winter has left rivers flowing higher than average and reservoirs near capacity. The California Department of Water Resources says that river flows range from about 20-percent above average in the Sacramento River near Shasta, to double the average flows in the San Joaquin and Kings Rivers. David Rizzardo, the department’s chief of snow surveys and water supply forecasting said the heat wave is causing even more runoff.

What a Wet Winter Means for Wildfire Season

Every spring firefighters throughout the West approach the summer season with a proverbial prediction: If the winter was dry, all those parched trees will burn like torches; if it was a wet winter, all those new grasses will fuel quick fire starts and hot, runaway flames. After a winter that left record piles of snow in the mountains and drenched most of California’s valleys, it’s no surprise that it is grass fires that are fueling a fast start to the state’s 2017 fire season. More than 16,000 acres had burned by June 3 in 1,229 blazes, most of them in central and southern California.

Dams: ‘Relics’ Or Vital To An ‘All Of The Above’ Fix?

As the West struggles with climate change, drought and rapid population growth, talk about the region’s deepening water woes often boils down to a simple but complicated question. Build more dams and other infrastructure, or ramp up conservation? E&E News put that question to two leading players with strong competing views. Daniel Beard, the commissioner of the Bureau of Reclamation in the Clinton administration, is widely credited with shifting the agency’s mission from unrestrained irrigation and water development to environmental management.
