DRAINAGE AREA - 1,801 mi².
DISCHARGE: July to December 1903; August 1904 to June 1921, published as "near Rome"; October 1938 to September 1994, published as "at Rome" (station 02396000). October 1994 to current year.

COOPERATION - U. S. Army Corp of Engineers, Mobile District.
For period 10/01/2013 - 10/18/2018: Discharge record fair. Gage height record good.
For period 10/19/2018 - 08/27/2019: Discharge record poor. Gage height record poor.
For period 08/28/2019 - 12/08/2020: Discharge record fair. Gage height record fair.
For period 12/09/2020 - 02/03/2021: Discharge record fair. Gage height record good.
