-M = Missing data.
* = Analysis may not provide a valid measure of conditions.
N/A = No average available.

If the Basin-wide percent of average 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 represents the depth of water in the snowpack, if the
snowpack were melted, expressed in inches.

The YEAR-TO-DATE PRECIPITATION Percent of Average represents the total precipitation
(beginning on October 1st) found at selected SNOTEL sites in or near the basin
compared to the average value for those sites on this day.
