Data from a SNOTEL site in Elko County, Nevada. SNOTEL is an automated system of snowpack and related climate sensors operated by the Natural Resources Conservation Service (NRCS) of the United States Department of Agriculture in the Western United States. There are over 900 SNOTEL (or snow telemetry) sites in 11 states, including Alaska.
The large panel in the foreground is the snow pillow. A snow pillow is a device for measuring snowpack, especially for automated reporting stations such as SNOTEL.. The snow pillow measures the water equivalent of the snow pack based on hydrostatic pressure created by overlying snow. [1]
Snow depths and density vary with time and location. At the Blazed Alder Creek station, the highest of the three at 3,650 feet (1,110 m) above sea level, the mean snow-water equivalent (SWE) (the amount of water in the accumulated snow) ranged in 2009 from 0 in July–October to about 50 inches (1,300 mm) in April.

The multiyear drought that has gripped Oregon is at its lowest point since October 2019. As a whole, Oregon's snowpack is 104% of normal while precipitation is 105% of normal.
Oregon got between 40 and 70 inches of snow in the Cascade Range and is now at 99% of normal for snowpack and 97% of normal for precipitation. ... also for our long-term snowpack and water supply ...
A winter weather advisory has been issued for around a foot of snow on Oregon’s Cascade mountain passes this weekend. The advisory lasts from 5 a.m. Saturday into 11 a.m. on Sunday.
The United States National Water and Climate Center collects and disseminates water resources and climate data. [1] It is part of the Natural Resources Conservation Service of the United States Department of Agriculture (USDA). The offices are located in Portland, Oregon, near Lloyd Center. [2] Services include:
In the early 1920s snow survey science and water supply forecasting had proven more than valuable in predicting the volume of water that would flow down the streams and into valleys each year. [38] Oregon was among the many western states that had begun establishing snow courses and taking snow surveys throughout their mountain ranges based on ...
