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.

02203655 SOUTH RIVER AT FOREST PARK ROAD, AT ATLANTA, GA
LOCATION - Lat 33°40'44.1", long 84°21'29.3" referenced to North American Datum of 1983, Fulton County, GA, Hydrologic Unit 03070103, on right upstream bank of Forrest Park Road, 0.05 miles downstream of Poole Creek, 0.4 miles upstream of South River Tributary and 1.7 miles upstream of Intrenchment Creek.
DRAINAGE AREA - 22.5 mi².
SURFACE-WATER RECORDS
PERIOD OF RECORD -
DISCHARGE: November 2002 to current year.
GAGE-HEIGHT: November 2002 to current year.

Data for parameter code 63680 (turbidity) were collected using a probe with the following specifications: turbidity, water, monochrome near infra-red LED light, 780-900 nm, detection angle 90 +/-2.5 degrees, FNU (Formazin Nephelometric Units). Before October 1, 2004, turbidity data were published using parameter code 00076: turbidity, water, unfiltered, NTU (Nephelometric Turbidity Units). Water sample constituent analysis is by the U.S. Geological Survey, National Water Quality Laboratory (USGS-NWQL). Laboratory sediment analyses are by the U.S. Geological Survey, Iowa Water Science Center, Iowa Sediment Laboratory. Field determinations of discharge, gage height, microbiology, specific conductance, pH, water temperature, air temperature, turbidity, and dissolved oxygen are by the U.S. Geological Survey.
