Caveats
- This is a statewide figure: the sum of each station's 1 April reading divided by the sum of each station's median, times 100.
- Each station needs at least 10 years of record before NRCS gives it a median; years before 1981 are excluded for this reason.
- The number of contributing stations changes year to year as Idaho's SNOTEL network has grown.
- Values are rounded to the nearest whole percent.
Measures
- Snow water equivalent, percent of median (percent): 1 April snow water equivalent as a percent of the 1991-2020 median, aggregated statewide across active SNOTEL stations.
