02318500 WITHLACOOCHEE RIVER AT US 84, NEAR QUITMAN, GA

LOCATION - Lat 30°47'35.9", long 83°27'12.4" referenced to North American Datum of 1983, Brooks County, GA, Hydrologic Unit 03110203, on downstream side of the US 84 bridge, 4.0 miles upstream from Piscola Creek, 6.0 miles east of Quitman, and 9.0 miles downstream from Little River.

DRAINAGE AREA - 1,480 mi².

REVISIONS HISTORY - WSP 1304; drainage area.

SURFACE-WATER RECORDS

PERIOD OF RECORD -
DISCHARGE: October 1928 to December 1931, June 1937 to May 1948, October 1988 to May 1992, June 1993 to current year.
GAGE HEIGHT: October 1993 to current year.

GAGE - Satellite telemetry with a water-stage recorder. Datum of gage is 83.4 feet above the North American Vertical Datum (NAVD) of 1988 (leveling by Global Positioning System equipment). From October 1, 1928 to December 11, 1931, a non-recording gage was located at same site at datum 5.0 feet lower. From June 9, 1937 to May 31, 1948, a non-recording gage was located at same site and datum. From May 19, 1949 to March 1, 1954, a crest-stage gage was located at same site and datum. From September 29, 1988 to May 4, 1989, a water-stage recorder was located at a site 2,000 feet upstream at same datum.

COOPERATION - USGS National Water-Quality Assessment Program.

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 recorded, 62,000 cfs, April 4, 1948; maximum gage-height recorded, 34.67, April 5, 2009; minimum daily discharge, 5.8 cfs, August 24, 2007.

CLIMATOLOGICAL RECORDS

PERIOD OF RECORD - April 2003 to September 2005. October 2008 to current year.

INSTRUMENTATION - Tipping-bucket raingage.

WATER-QUALITY RECORDS

PERIOD OF RECORD - November 2004 to August 2005.

REMARKS - Laboratory chemical analyses are by the U.S. Geological Survey, National Water Quality Laboratory. Field determinations of discharge, specific conductance, pH, water temperature, turbidity, dissolved oxygen, and alkalinity are by the U.S. Geological Survey.
