SURFACE-WATER RECORDS

PERIOD OF RECORD -
DISCHARGE: January 1927 to December 1931, April 1937 to current year. Monthly discharge only for April 1937, published in WSP 1304.
GAGE-HEIGHT: January 1921 to September 1923 (gage-heights only), October 1986 to current year.

GAGE - Satellite telemetry with a water-stage recorder. Datum of gage is 91.0 feet above the North American Vertical Datum (NAVD) of 1988 (leveling by Global Positioning System equipment). From January 27, 1921 to September 30, 1923, a non-recording gage was located at site 1,200 feet upstream at datum 3.00 feet higher. From January 27, 1927 to December 31, 1931 and from April 20, 1937 to June 10, 1938, a non-recording gage was located at site 1,000 feet upstream at datum 1.00 feet higher. From June 11, 1938 to November 26, 1952, a non-recording gage was located at site 1,000 feet upstream at present datum. From October 14, 1960 to October 29, 1970, an auxiliary water-stage recorder was located at a site about 3.0 miles upstream, and since November 5, 1971, an auxiliary water-stage recorder was located at a site about 2.0 miles upstream.

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

REMARKS - Gage-height records are generally fair. 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.
