DRAINAGE AREA - 31,200 mi² of which 3,800 mi² probably is noncontributing.
REVISIONS HISTORY - Revisions: Maximum discharge for water year 2020 was revised on May 5, 2021, based on changes to the shifting of the stage-discharge rating.
PERIOD OF RECORD - DAILY DISCHARGE--1936-37, 1941-47 (high-water periods only), April 1948 to September 1960 (spring and summer months only), October 1973 to September 1976, October 1984 to September 2001 (peak gage height and discharge only), April 2002 to current year (maximum discharge only).

PERIOD OF RECORD.--DAILY GAGE HEIGHT--April 2002 to current year.
GAGE - Water stage recorder.Datum of gage is 773.74 ft above North American Vertical Datum of 1988 (NAVD88). Prior to conversion to NAVD88, datum was  published as 772.79 ft above NGVD29.

For periods 1936, 1937, 1941-47; non-recording gage at railroad bridge 200 ft. upstream at datum 777.79 ft above NGVD29.

Miscellaneous discharge measurements were made during the water year.
