Sierra Nevada snowpack not likely to recover from drought until 2019

Even with this winter’s strong El Niño, the Sierra Nevada snowpack will likely take until 2019 to return to pre-drought levels, according to new research.

Additionally, researchers suggest their new method, which provided unprecedented detail and precision, could be useful in characterizing water in the snowpack in other mountains, including ranges in western North America, the Andes or the Himalayas. These areas currently have much less on-site monitoring than in the Sierra Nevada.

The new study was published today in Geophysical Research Letters, a journal of the American Geophysical Union.
