02172040 BACK RIVER AT DUPONT INTAKE NEAR KITTREDGE, SC
LOCATION - Lat 33°03'25", long 79°57'30" referenced to North American Datum of 1927, Berkeley County, SC, Hydrologic Unit 03050201, on downstream side of bridge crossing Durham canal located on Secondary Road 9, and at mi 1.7. (revised)
SURFACE-WATER RECORDS
PERIOD OF RECORD -

Gage Height: October 1990 to current year. Records prior to October 1990 are in the files of the U.S. Geological Survey.

Discharge: September 2013 to current year.

GAGE - Data collection platform and Acoustic Velocity Meter. Datum of gage is 15.15 ft below NAVD of 1988 datum.
REMARKS -
Astronomical tides cause significant cycles of approximately 24.8 hours at this site. Tidal effects were removed from unit value discharges using the Godin filter.
For water year 2020: Records good to fair.
EXTREMES FOR PERIOD OF RECORD - Maximum discharge, unknown, Maximum gage height 21.68 ft, Oct. 4, 2015; minimum discharge, -7,270 ft³/s, February 20, 2019, minimum gage height, 11.92 ft, Mar. 14, 1993.
