SURFACE-WATER RECORDS
PERIOD OF RECORD -
DISCHARGE: August 2003 to April 2007 (discharge measurements only), April 2007 to current year. Published as South River Tributary at Springdale Road, At Atlanta, October 2004 to September 2008.
GAGE HEIGHT: April 2007 to current year. Published as South River Tributary at Springdale Road, At Atlanta, October 2004 to September 2008.
GAGE - Satellite telemetry with a water-stage recorder. Datum of gage is 847.08 feet above North American Vertical Datum (NAVD) of 1988 (leveling by Global Positioning System equipment). Prior to April 2007, non-recording gage at same site and datum.

For period 10/01/2014-09/30/2015: Continuous water temperature record is good, specific conductance, dissolved oxygen and pH records are fair, and turbidity record is poor.
For period 10/01/2015-09/30/2016: Continuous water temperature record is good, specific conductance, dissolved oxygen and pH records are fair, and turbidity record is poor.
For period 10/01/2016-09/30/2017: Continuous water temperature record is good, specific conductance, dissolved oxygen and pH records are fair, and turbidity record is poor.
For period 10/01/2017-09/30/2018: Continuous water temperature record is good, specific conductance, dissolved oxygen and pH records are fair, and turbidity record is poor.
For period 10/01/2018-09/30/2019: Continuous water temperature record is good, specific conductance, dissolved oxygen and pH records are fair, and turbidity record is poor.
For period 10/01/2019-09/30/2020: Continuous water temperature record is good, specific conductance, dissolved oxygen and pH records are fair, and turbidity record is poor.

Data for parameter code 63680 (turbidity) were collected using a probe with the following specifications: turbidity, water, monochrome near infra-red LED light, 780-900nm, 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). Field determinations of discharge, microbiology, specific conductance, pH, water temperature, turbidity, and dissolved oxygen are by the U.S. Geological Survey.
