USGS Water-Year Summary 2023

02217643 PARKS CREEK AT LYLE FIELD ROAD NEAR JEFFERSON, GA

LOCATION - Lat 34°09'43.41", long 83°31'30.34" referenced to North American Datum of 1983, Jackson County, GA, Hydrologic Unit 03070101, at Lyle Field Road, 4.3 miles from confluence with North Oconee River and 4.3 miles northeast of Jefferson, Ga.

DRAINAGE AREA - 3.05 mi².

REVISIONS HISTORY - Gage datum was revised on January 13, 2022, based on an error in the determination of the gage datum.

SURFACE-WATER RECORDS

PERIOD OF RECORD -
DISCHARGE: September 2012 to current year.
GAGE HEIGHT: September 2012 to current year.

GAGE - Satellite telemetry with a water-stage recorder. Datum of gage is 714.55 feet above North American Vertical Datum (NAVD) of 1988 (from GNSS survey).

COOPERATION - City of Jefferson.

REMARKS - Gage-height records are generally fair. 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, 576 cfs, April 19, 2019; maximum gage height recorded, 7.69 feet, April 19, 2019; minimum daily discharge, 0.25 cfs, estimated, June 24, 2018.

CLIMATOLOGICAL RECORDS

PERIOD OF RECORD - September 2012 to October 2017.

INSTRUMENTATION - Tipping-bucket raingage.

WATER-QUALITY RECORDS

PERIOD OF RECORD - November 2012 to current year.

PERIOD OF DAILY RECORD -
SPECIFIC CONDUCTANCE: November 2012 to current year.
PH: November 2012 to current year.
WATER TEMPERATURE: November 2012 to current year.
DISSOLVED OXYGEN: November 2012 to current year.
TURBIDITY: November 2012 to current year.

INSTRUMENTATION - Satellite telemetry and a continuous water-quality monitor.

REMARKS - Water temperature records are rated good. Specific conductance records are good. pH records are fair. Dissolved Oxygen records are good. Turbidity records are poor. Data for parameter code 63680 (turbidity) were collected using a probe with the following specifications: turbidity, water, monochrome near infra-red LED light, 780-900 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).
