Units = inches for the Current and Median (or Average) Snow Water Equivalent and Total Precipitation values If the Basin Index (%) value is flagged as potentially invalid, care should be taken to evaluate if the value is representative of conditions in the basin. The SNOW WATER EQUIVALENT Percent of Median (or Average) represents the 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 TOTAL PRECIPITATION Percent of Median (or Average) represents the total precipitation (beginning October 1st) found at selected SNOTEL sites in or near the basin compared to the Median (or Average) value for those sites on this day. 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 medians (or averages) 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.
