-M = Missing data.
* = Analysis may not provide a valid measure of conditions.
N/A = Not available.

Footnotes for median and average:
(##) = If less than 30 years are available, this value specifies the number of years used for the median and average calculations.
Sites with less than 10 years available do not have medians or averages.

The % Monthly Total represents the precipitation accumulated from the 1st day of the current
month through the current day found at selected SNOTEL sites in or near the basin compared
to the Median (or Average) total precipitation for the current month for those sites.

The % Annual Total represents the precipitation accumulated from the start of the water year
(Oct 1) through the current day found at selected SNOTEL sites in or near the basin compared
to the Median (or Average) total precipitation for the entire water year for those sites.

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 normals 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.
