USGS Water-Year Summary 2023
02336526 PROCTOR CREEK AT JACKSON PARKWAY, AT ATLANTA, GA
LOCATION - Lat 33°47'40.1", long 84°28'27.1" referenced to North American Datum of 1983, Fulton County, GA, Hydrologic Unit 03130002, on the upstream left bank of bridge on Jackson Parkway (GA 280).
DRAINAGE AREA - 13.4 mi².
SURFACE-WATER RECORDS
PERIOD OF RECORD -
DISCHARGE: October 1961 to September 1990(maximum only), December 2002 to current year.
GAGE-HEIGHT: October 1961 to September 1990 (maximum only), December 2002 to current year.
GAGE - Satellite telemetry with water-stage recorder and a continuous water-quality monitor. Datum of gage is 758.83 feet above NAVD88. Datum of gage is unknown prior to December 2002.
COOPERATION - City of Atlanta.
REMARKS - Gage-height records are generally good. 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.
EXTREMES FOR PERIOD OF RECORD - Maximum discharge recorded, 8,000 cfs, May 16, 2003, from rating extended above 1,100 cfs on basis of slope-area measurement of peak flow; maximum gage-height recorded, 18.03 feet, at datum then in use, March 13, 1975; minimum daily discharge, 0.70 cfs, September 24, 2012.
CLIMATOLOGICAL RECORDS
PERIOD OF RECORD - December 2002 to current year.
INSTRUMENTATION - Tipping-bucket raingage.
WATER-QUALITY RECORDS
PERIOD OF RECORD - May 1976 to May 1977, July 2003 to current year.
PERIOD OF DAILY RECORD -
SPECIFIC CONDUCTANCE: April 2003 to current year.
pH: April 2003 to current year.
WATER TEMPERATURE: April 2003 to current year.
DISSOLVED OXYGEN: April 2003 to current year.
TURBIDITY: April 2003 to current year.
INSTRUMENTATION - Satellite telemetry with a continuous water-quality monitor.
REMARKS -
For period: 10/01/2014-09/30/2015: Specific conductance, pH, and water temperature record is rated good. Dissolved oxygen record is rated fair. Turbidity record is rated poor.
For period: 10/01/2015-09/30/2016: Specific conductance, pH, water temperature, and dissolved oxygen record is rated good. Turbidity record is rated fair.
For period: 10/01/2016-09/30/2017: Specific conductance, pH, water temperature, dissolved oxygen and turbidity record is rated fair.
For period: 10/01/2017-09/30/2018: Specific conductance, pH, water temperature, dissolved oxygen and turbidity record is rated fair.
For period: 10/01/2017-09/30/2018: Specific conductance, pH, water temperature, dissolved oxygen and turbidity record is rated fair.

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). Prior to October 1, 2004, turbidity data were published using parameter code 00076: turbidity, water, unfiltered, NTU (Nephelometric Turbidity Units). Hydrologic event 9 indicates a routine sample while J designates a storm event sample. Laboratory sediment analyses are by the U.S. Geological Survey, Kentucky Sediment Laboratory. Field determinations of discharge, gage height, specific conductance, pH, water temperature, turbidity, barometric pressure, microbiology, air temperature, and dissolved oxygen are by the U.S. Geological Survey.
