USGS Water-Year Summary 2023

02337410 DOG RIVER AT GA 5, NEAR FAIRPLAY, GA

LOCATION - Lat 33°39'13.7", long 84°49'15.7" referenced to North American Datum of 1983, Douglas County, GA, Hydrologic Unit 03130002,

DRAINAGE AREA - 66.5 mi².

SURFACE-WATER RECORDS

PERIOD OF RECORD -
DISCHARGE: June 2007 to current year.
GAGE HEIGHT: June 2007 to current year.

GAGE - Satellite telemetry with a water-stage recorder and continuous water-quality monitor. Datum of gage is 851.94 feet above the North American Vertical Datum (NAVD) of 1988 (leveling by Global Positioning System equipment).

COOPERATION - Douglasville-Douglas County Water and Sewer Authority.

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.

EXTREMES FOR PERIOD OF RECORD - Maximum discharge, 59,900 cfs, September 21, 2009, from rating curve extended above 9,200 cfs on basis of contracted opening measurement of peak flow; maximum gage-height, 33.83 feet, from floodmarks, September 21, 2009; minimum daily discharge, 1.0 cfs, August 23, 2007.

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). Hydrologic event 9 indicates a routine sample while J designates a storm event sample. Laboratory chemical analyses are by the U.S. Geological Survey, National Water-Quality Laboratory, Denver, CO and RTI Laboratories, Livonia, MI. Laboratory sediment analyses are by the U.S. Geological Survey, Kentucky Sediment Laboratory. Field determinations of discharge, bacteria, specific conductance, pH, water temperature, turbidity, barometric pressure and dissolved oxygen are by the U.S. Geological Survey.

EXTREMES FOR PERIOD OF DAILY RECORD -
SPECIFIC CONDUCTANCE: Maximum recorded, 165 microsiemens, January 16, 2022; minimum recorded, 14 microsiemens, February 17, 2023.
WATER TEMPERATURE: Maximum recorded, 33.4 °C, July 1, 2012; minimum recorded, -0.1 °C, January 18, 2018.
