USGS Water-Year Summary 2023

02387000 CONASAUGA RIVER AT TILTON, GA

LOCATION - Lat 34°40'00.9", long 84°55'40.5" referenced to North American Datum of 1983, Whitfield County, GA, Hydrologic Unit 03150101,
On left bank 250.0 feet downstream from Tilton Road Bridge, 0.6 mi downstream from confluence with Swamp Creek, 2.7 mi upstream from confluence with Howell Creek, 12.0 mi upstream from confluence with Coosawattee River, and 0.5 mi northeast of Tilton.

DRAINAGE AREA - 687 mi².

REVISIONS HISTORY - WRD GA-80-1: Drainage area.

SURFACE-WATER RECORDS

PERIOD OF RECORD -
Discharge: June 1937 to current year.
Gage height: October 1998 to current year.

GAGE - Satellite telemetry with a water-stage recorder and a continuous water-quality monitor. Datum of gage is 622.16 feet above North American Vertical Datum (NAVD) of 1988 (GNSS survey). Prior to August 24, 1940, a non-recording gage was located at site 150 feet upstream at same datum. Since October 1, 1979, an auxiliary water-stage recorder was located at Sloan Road Bridge, 3.2 miles downstream. A water-stage recorder on Oostanaula River at Resaca was used as auxiliary gage during 1961-79 water years.

COOPERATION - U.S. Army Corps of Engineers, Mobile District; Georgia Department of Natural Resources, Environmental Protection Division.

REMARKS - Gage-height records are generally good. Discharge records are generally good 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.

Flow affected by withdrawals and return flow by the City of Dalton.

EXTREMES FOR PERIOD OF RECORD - Maximum discharge, 36,800 cfs, (Gage height 29.89 feet), February 17, 1990; maximum gage height recorded, 30.20 feet, backwater from Coosawattee River, March 30, 1951; minimum daily discharge, 9.4 cfs, August 25, 2007.

WATER-QUALITY RECORDS

PERIOD OF RECORD - September 1941, October 1942 to September 1943, June 1957 to current year.
