SURFACE-WATER RECORDS

PERIOD OF RECORD -
DISCHARGE: March 1892 to September 1905 (prior to October 1896, gage heights only), October 1936 to current year. Monthly discharge only for January to March 1896, published in WSP 1304. Gage heights collected at same site since 1892 are contained in reports of National Weather Service.
GAGE HEIGHT: October 1998 to current year. Gage heights collected at same site since 1892 are contained in reports of National Weather Service.

GAGE - Satellite telemetry with a water-stage recorder. Datum of gage is 844.6 feet above North American Vertical Datum (NAVD) of 1988. From March 1892 to December 1905, a non-recording gage was located at site 100.00 feet upstream at datum 2.00 feet higher. From March 16, 1937 to January 17, 1939, a non-recording gage was located at site 100.00 feet upstream at present datum. A water-stage recorder at Allatoona Reservoir is used as an auxiliary gage for this station during periods of backwater caused by Allatoona Reservoir.

COOPERATION - U.S. Army Corps of Engineers, Mobile District.

REMARKS - Gage-height records are generally good. Discharge records are generally fair except for estimated discharges, which are poor. Additional details on the accuracy of the records can be obtained by contacting the USGS South Atlantic Water Science Center at gs-w-ga_nwisweb_data_inquiries@usgs.gov.

EXTREMES OUTSIDE PERIOD OF RECORD - Maximum discharge, 36,700 cfs, January 1892; gage height, 25.00 feet, January 1892.

EXTREMES FOR PERIOD OF RECORD - Maximum discharge recorded, 32,300, January 7, 1946; maximum gage height recorded, 26.70 feet, January 7, 1946; minimum daily discharge, 81 cfs, October 1, 2007.
