   The Snow Water Equivalent Percent of Average represents the snow
   water equivalent found at selected SNOTEL sites in or near the
   basin compared to the average 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 Average Snow Water Equivalent and
        Total Precipitation values

          Reference period for average conditions is 1971-2000.
