Prior to October 1939 (published as "at Le Claire"), discharges include flow from Wapsipinicon River. Minor flow regulation by navigation dams since about 1938 - should not significantly affect monthly discharges and should have only minor affect on daily discharges. Daily and longer averages for 115 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.
