Comments and qualifications on the data:
   Winter records may be ice affected. Records prior to water year 1971 are unsuitable for analysis at less than
   monthly resolution due to minor low flow regulation by upstream plant.


Monthly and longer averages for 55 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.
