Warming Climate, Low Sierra Snowpack, Evaporating Runoff Extend California Drought

/in , , /by /CBS SF Bay Area

Skiers and snowboarders pray for snow so they can shred the slopes. Climatologists and hydrologists have an entirely different and more critical reason to cross their fingers for the “white gold.”

The West’s historic drought has many impacts, including water shortages, more severe wildfire seasons and unprecedented heat waves, to name a few. Intense droughts are a result of many factors, one of which scientists have recently begun to analyze with more scrutiny: snow drought.

New Federal Report Show Increasing Groundwater Levels in the Coachella Valley

/in , /by /CVWD.org

A new report by the U.S. Geological Survey shows that efforts by Coachella Valley Water District to replenish local aquifers in the Coachella Valley have been effective, leading to stable land surface elevations in most of the Coachella Valley. Areas with land subsidence identified in prior studies are now stable, uplifting, or experiencing substantial slowing of subsidence. CVWD partners with Coachella Water Authority, Desert Water Agency, Indio Water Authority, and Mission Springs Water District to manage groundwater in the Coachella Valley.

After the Blazes: Poisoned Water and ‘a Flood on Steroids’

Historic wildfires raging from California to Colorado are weakening watersheds and setting the stage for deadly mudslides and flooding and, in some places, threatening to poison critical water supplies.

If you’re reading this, chances are you don’t really have to think about where your drinking water is coming from, how your food was grown, or what effects such processes have had on the environment. Specifically, in reference to our drinking water, around half of the US population gets their drinking water from either public or private wells.

Climate Change Has Stolen More Than a Billion Tons of Water From the West’s Most Vital River

/in , , /by /Washington Postby Juliet Eilperin

The Colorado River’s average annual flow has declined by nearly 20 percent compared to the last century, and now a new study has identified one of the main culprits: Climate change is causing mountain snowpack to disappear, leading to increased evaporation.

Four recent studies have found that up to half of the drop in the Colorado’s average annual flow since 2000 has been driven by warmer temperatures. Now, two U.S. Geological Survey researchers have concluded that much of this climate-induced decline — amounting to 1.5 billion tons of missing water, equal to the annual water consumption of 10 million Americans — comes from the fact that the region’s snowpack is shrinking and melting earlier. Having less snow to reflect heat from the sun, known as the albedo effect, creates a feedback loop, they say.
