The Snow Water Equivalent Percent of Median represents the snow
water equivalent found at selected SNOTEL sites in or near the
basin compared to the Median value for those sites on this day.
The Accumulated Precipitation Percent of Average represents the
total precipitation (beginning October 1st) found at selected
SNOTEL sites in or near the basin compared to the Average value
for those sites on this day.
* = Data are not available or data may not provide a valid measure
of conditions for over half of the sites within the basin.
Refer to the individual state reports for a complete data
listing and basin analysis.
Units = inches for the Current and Normal Snow Water Equivalent and
Total Precipitation values
Medians and averages are calculated for the period 1981-2010.
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 for the day is less than 10% of the maximum
median value for the year.
* Basin - More than half of the sites within the basin are flagged with *,
preventing the calculation of a meaningful basin index.
The basin index is calculated as the sum of the valid current values
divided by the sum of the corresponding medians (for snow water equivalent)
or averages (for precipitation) and the resulting fraction multiplied by 100.
