Comments and qualifications on the data:
Records are not suitable for analysis at less than monthly resolution because there is a minor effect on low flow
by several distant upstream reservoirs. Starting with water year 1981, high flows have been affected by dam
upstream.
Monthly and longer averages for 42 water years are acceptable (some whole years and all partial years are excluded).
A water year with acceptable data is indicated by an asterisk in the time line, which spans 1874 through 1988.
