Comments and qualifications on the data:
   Records are unsuitable for analysis at less than monthly resolution currently due to minor municipal withdrawal
   upstream from gage and prior to 1960, due to diurnal fluctuations at low and medium stages induced by mills and
   powerplants upstream. ME

Daily and longer averages for 58 water years are acceptable (all years except partial years).
A water year with acceptable data is indicated by an asterisk in the time line, which spans 1874 through 1988.
