-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.
If the Basin Index (%) percent 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 WATER YEAR-TO-DATE-PRECIPITATION represents total precipitation since October 1st, expressed in inches.
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.
