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.

GAGE-HEIGHT: October 1995 to January 1997 (continuous record); 1998 to May 17, 2001 (non-continuous record); May 17, 2001 to current year.
GAGE - Satellite telemetry with a water-stage recorder and a continuous water-quality monitor. Datum of gage is 923.99 feet above NAVD88. From October 1, 1995 to January 6, 1997, continuous recorder at same site. From 1998 to May 17, 2001, operated as a crest-stage gage at same location.
COOPERATION - Gwinnett County Department of Water Resources.
REMARKS - Gage-height records are generally good. Discharge records are generally good 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.

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 chemical analyses are by RTI Laboratories, Livonia, MI. Laboratory sediment analyses are by the U.S. Geological Survey, Kentucky Sediment Lab. Field determinations of discharge, air temperature, gage height, specific conductance, pH, water temperature, turbidity, barometric pressure and dissolved oxygen are by the U.S. Geological Survey.
