COOPERATION - Georgia Department of Natural Resources, Environmental Protection Division.
INSTRUMENTATION - Satellite telemetry with a continuous water-quality monitor.
REMARKS -

Discrete Water-quality Records:  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.

Continuous Water-quality Records:

For period 10/01/2017 to 09/30/2018:  Specific Conductance, pH, Water Temperature, and Dissolved Oxygen are rated good. 

For period 10/01/2018 to 03/11/2019:  Specific Conductance, pH, Water Temperature, and Dissolved Oxygen are rated good.
