The snowpack in Washington's mountain ranges has seen as much as a 60% decrease over 75 years and that trend will likely continue for the rest of the century. Historically, peak snowpack hits April 1. The USDA reports that for most places in Oregon, Washington and Idaho, peak snowpack is happening one to three weeks earlier in the year. In Washington, most areas’ snowpack is down between 20 to 30%, with some areas decreasing as much as 50 to 60%. Looking forward, those trends continue. A University of Washington report projects that in the 4,000 to 5,000 foot range of the Cascades, the length of the snow season could decrease by nearly half by the end of the 21st century. This means that the historical 142 days of snow on the ground in the second half of the 20th century will drop to 87 days on average in the 2080s.
