-M = Missing data.
* = Analysis may not provide a valid measure of conditions.
N/A = Not available.

Footnotes for median and average:
(##) = If less than 30 years are available, this value specifies the number of years used for the median and average calculations.
Sites with less than 10 years available do not have medians or averages.

The snow water equivalent percent of median (or average) represents the current snow water
equivalent found at selected SNOTEL sites in or near the basin compared to the median (or average) value
for those sites on this day.

The snow water equivalent percent of median (or average) peak represents the current
snow water equivalent at selected SNOTEL sites in or near the basin compared to the median (or average)
of the maximum seasonal values observed each water year for those sites.

Contact your state water supply staff for assistance.

Medians and averages are calculated for the period 1991-2020.

Provisional data, subject to revision.
* Site -- Either: (a) the current value is missing; (b) the median or average for the day is not available or is zero; or (c) for snow water equivalent, the median or average for the day is less than 10% of the maximum median or average value for the year.

* Basin - More than half of the stations for a basin with normals report missing or invalid data.

The basin index is calculated as the sum of the valid current values divided by the sum of the corresponding medians or averages and the resulting fraction multiplied by 100.
