Click to hide Water-Year Summary instructions and information
  • Water-Year Summary reports summarize a year of hydrologic data in a printer-friendly format.
  • For water years 2014 onward, choose a water year and parameter and an on-demand Water-Year Summary report will be generated.
  • For water years 2006 through 2013, choose a water year and an Annual Water Data Report will be provided.
  • For water years 2005 and earlier, Annual Water Data Reports may be available in digital format.
  • Not all sites have reports available for every water year.

USGS Water-Year Summary 2021
LOCATION - Lat 31°18'25", long 84°20'20" referenced to North American Datum of 1983, Baker County, GA, Hydrologic Unit 03130008, on downstream side of pier of bridge on GA 37, 16.24 mi upstream from confluence with Ichawaynochaway Creek, 0.8 mi downstream from confluence with Cooleewahee Creek, 0.5 mi southwest of Newton, and at mile 69.5.
DRAINAGE AREA - 5,740 mi². approximately.
REVISIONS HISTORY - Water temp data from 08/03/2019 to 08/13/2019 was revised following routine audit. Data was found to be erroneous and was removed from record, and a revised qualifier was added to instantaneous values. 
DISCHARGE: April 1938 to September 1950 (monthly discharge only for October 1945 to September 1946, October 1947 to December 1948, published in WSP 1304), October 1956 to current year.
GAGE-HEIGHT: October 1989 to current year.
GAGE - Satellite telemetry with a water-stage recorder. Datum of gage is 109.8 feet above the North American Vertical Datum (NAVD) of 1988 (levels by U.S. Army Corps of Engineers). Prior to November 12, 1956, a non-recording gage was located at same site and datum.
COOPERATION - U.S. Army Corps of Engineers, Mobile District.
For period 10/01/2013-01/15/2020: Discharge records good, except for those with Estimated Discharge which are poor. Gage height records good.

Flow regulated by power plants at Flint River Reservoir since 1921, with a capacity of 7,500 acre-ft; and at Warwick Reservoir since 1930, with a capacity of about 35,000 acre-ft. Normal operation of power plants does not materially affect figures of monthly runoff. Periods of monthly discharge only are not included in statistics computations.

EXTREMES FOR PERIOD OF RECORD - Maximum discharge recorded, 100,000 cfs, July 13, 1994; maximum gage height recorded, 45.25 feet, July 13, 1994; minimum daily discharge, 577 cfs, July 7, 2012.
PERIOD OF RECORD - May 2004 to current year.
INSTRUMENTATION - Tipping-bucket raingage.
PERIOD OF RECORD - February 1968 to June 1979, May 1981 to current year.
COOPERATION - Georgia Department of Natural Resources, Environmental Protection Division.
REMARKS - Analyzing agency is represented by the five-digit code listed under USGS Water Science Center special parameter code 99920. Laboratory analyses with analyzing agency code 81341 are by the Laboratory Services Section, Environmental Protection Division, Georgia Department of Natural Resources. Field determinations of Discharge, Specific Conductance, pH, Water Temperature, Air Temperature, and Dissolved Oxygen are by the U.S. Geological Survey.
