Time Series and Projection Charts

The chart products below include both time series and projections for either basins, sub-basins and/or individual SNOTEL sites. In addition to the chosen parameter, the charts include data from the historical record and statistical background data such as the maximum, normal and minimum water years, and shaded exceedance percentiles (10th, 30th, 50th, 70th and 90th). The user can select and compare any year(s).

Period of Record Snow Water Equivalent

Chart comparing the current snow water equivalent in inches to all other years from the historical record.




Period of Record Precipitation

Chart comparing the current accumulated precipitations in inches to all other years from the historical record.




Snow Water Equivalent Projections
