LOCATION - Lat 32°08'26.4", long 85°02'57.8" referenced to North American Datum of 1983, Stewart County, GA, Hydrologic Unit 03130003, at bridge on GA 39 Spur, 0.4 mi downstream from Seaboard Coast Line Railroad bridge, 2.2 mi downstream from Hannahatchee Creek, 2.4 mi southwest of Omaha, and at mile 119.7.
DRAINAGE AREA - 5,910 mi². revised.
REVISIONS HISTORY - WDR GA-2013: Drainage area.
SURFACE-WATER RECORDS
PERIOD OF RECORD -
DISCHARGE: September 2009 to current year.
GAGE-HEIGHT: September 2009 to current year.
WATER VELOCITY: September 2009 to current year.
GAGE - Satellite telemetry with a water-stage recorder and an acoustic velocity meter. Velocity data represents the average water velocity at the upstream cross-section of the bridge with positive values in the downstream direction. Datum of gage is North American Vertical Datum (NAVD) of 1988.
COOPERATION - Georgia Department of Natural Resources, Environmental Protection Division.
REMARKS -
For Period: 10/01/2013 - 09/30/2015: Discharge records fair, except for discharge below 3,000 cubic feet per second and days of estimated discharge which are poor. Gage Height records good. Water Velocity records fair.
For Period: 10/01/2015 - 10/18/2017: Discharge records poor. Gage Height records fair. Water Velocity records fair.
For Period: 10/18/2017 - 02/06/2019: Discharge records good, except for discharge below 3,000 cubic feet per second and days of estimated discharge which are poor. Gage Height records good. Water Velocity records good.
For Period: 02/06/2019 - 10/16/2019: Discharge records fair, except for discharge below 3,000 cubic feet per second and days of estimated discharge which are poor. Gage Height records fair. Water Velocity records fair.
For Period: 10/16/2019 - 08/12/2021: Discharge records good, except for discharge below 3,000 cubic feet per second and days of estimated discharge which are poor. Gage Height records good. Water Velocity records good.
For Period: 08/12/2021 - 12/09/2021: Discharge records good, except for discharge below 3,000 cubic feet per second and days of estimated discharge which are poor. Gage Height records good. Water Velocity records fair.

Water velocity data represent water velocity at the downstream cross-section of the bridge with positive values in the downstream direction.

EXTREMES FOR PERIOD OF RECORD - Maximum discharge recorded, 115,000 cfs, December 25-26, 2015; maximum gage-height recorded, 196.48 feet, December 25, 2015; minimum daily discharge, -686 cfs, September 3, 2012.
