Data on these pages show the estimated total snow water equivalent in each basin by year (Water Year 2004 to Current [2023]) as well as by elevation. These values do not represent the actual amount of water that will end up in streams since content will be lost to sublimation, evaporation, and infiltration but are modelled currently-on-the-ground values. Data are presented in a variety of views:

Maximum, minimum, median, and average volume for each elevation with the current water year's progress.
