How is the snowpack in Oregon?

Who measures snowpack?
NRCS
In 1979, NRCS and its partners began installing automated snowpack telemetry (SNOTEL) stations. Instruments at these stations automatically measure snowpack and related climatic data. The NRCS SNOTEL network now operates more than 800 remote sites in the western United States, including Alaska.

Density for the snowpack is calculated by dividing the snow water equivalent by the depth of the snow. Density can be used to measure variability across the snowcourse and is also used to quality control the samples taken.

Is the snowpack in the northwest going up or down?
While some stations have experienced increases in April snowpack, all 12 states included in this indicator experienced a decrease in snowpack on average from 1955 to 2020 (see Figure 1).
