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.
USGS Water-Year Summary 2024
02217274 WHEELER CREEK AT BILL CHEEK ROAD, NEAR AUBURN, GA
LOCATION - Lat 34°04'56", long 83°51'16" referenced to North American Datum of 1983, Gwinnett County, GA, Hydrologic Unit 03070101, at concrete box culvert on Bill Cheek Road.
DRAINAGE AREA - 1.31 mi².
REVISIONS HISTORY -
Discharge for the period Aug. 14, 2017, to Oct. 23, 2017, was revised on May 11, 2019, based on changes to the shifting of the stage-discharge rating.
Discharge for the period Apr. 19, 2019, was revised on Nov. 2, 2019, based on additional estimates of discharge during this period.
SURFACE-WATER RECORDS
PERIOD OF RECORD -
DISCHARGE: June 2001 to current year.
GAGE-HEIGHT: June 2001 to current year.
DISCHARGE: June 2001 to current year.
GAGE-HEIGHT: June 2001 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). 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 Laboratory. Field determinations of discharge, gage height, air temperature, Specific Conductance, pH, Water Temperature, Dissolved Oxygen, Barometric Pressure, and Turbidity are by the U.S. Geological Survey.
