   And they go on to say –

   * = 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.

   Why are more than half flagged?
