Winter snows are accumulating in the Sierra Nevada Mountains, creating the snowpacks that serve as a primary source of water for the western U.S.
A future warmer world will almost certainly feature a decline in fresh water from the Sierra Nevada mountain snowpack. Now a new study by the Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) that ...
As farmers in the American West decide what, when and where to plant, and urban water managers plan for water needs in the next year, they want to know how much water their community will get from melting snow in the mountains.
It's said on sticky summer days: "It's not the heat, it's the humidity." That holds true in the winter too, and could hold the key to the future of snowpack and water resources in the American West.
New research suggests that "flash droughts"—like the one that unexpectedly gripped the Southern Rockies and Midwest in the summer of 2012—could be predicted months in advance using soil moisture and snowpack data.
Snowpack in California's Sierra Nevada in 2015 was at the lowest level in the past 500 years, according to a new report led by University of Arizona researchers.
A new report projects that by the middle of this century there will be an average 56 percent drop in the amount of water stored in peak snowpack in the McKenzie River watershed of the Oregon Cascade Range - and that similar ...
(PhysOrg.com) -- The researchers evaluated the recent declines using snowpack reconstructions from 66 tree-ring chronologies, looking back 500 to more than 1,000 years.
There has been sharp disagreement in recent years about how much, or even whether, winter snowpack has declined in the Cascade Mountains of Washington and Oregon during the last half-century.
