SURFACE-WATER RECORDS

PERIOD OF RECORD -
DISCHARGE: July 1897 to December 1912, January 1913 to September 1997 (annual maximum discharge only), September 1997 to current year. Prior to January 1, 1918, published as "near Carlton" (02191500).
GAGE HEIGHT: October 1998 to current year.

GAGE - Satellite telemetry with water-stage recorder. Datum of gage is 406.6 feet above North American Vertical Datum (NAVD) of 1988 (leveling by Global Navigation Satellite System equipment using GEOID12A). Prior to January 1, 1918, a non-recording gage was located at Seaboard Coast Line Railway bridge about 0.75 miles downstream at datum 5.67 feet lower. From January 1, 1918 to September 1936, a non-recording gage was located at bridge 100 feet upstream at same datum. From October 1936 to April 1954, a non-recording gage was located at present site and datum.

COOPERATION - Georgia Department of Natural Resources, Environmental Protection Division.

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 FOR PERIOD OF RECORD - Maximum discharge recorded, 70,000 cfs, August 25, 1908; maximum gage height recorded, 39.00 feet, at site and datum then in use, August 25, 1908; minimum daily discharge, 15 cfs, September 13, 2002.
