These bands describe share of capacity, not drought severity - some reservoirs are held near the top of a narrow band by design. How they are defined.
"% of date avg" compares today's storage with the average storage on this calendar date across each reservoir's CDEC record (mostly since 1985) - the quickest honest answer to "is this normal for this time of year?".
