USGS Water-Year Summary 2020
LOCATION - Lat 33°39'39", long 79°09'17" referenced to North American Datum of 1927, Horry County, SC, Hydrologic Unit 03040201, near the north bank of the Pee Dee River attached to an old bridge piling at Highway 701, 12.5 mi southwest of Myrtle Beach, 13.0 mi south of Conway, and 3.0 mi south of the mouth of Little Pee Dee River.
DRAINAGE AREA - 14,100 mi².
PERIOD OF RECORD - October 2001 to May 2013, July 2014 to current.
GAGE - Data collection platform and Acoustic Velocity Meter. Datum of gage is 7.92 ft below NGVD of 1929.
REMARKS - Astronomical tides cause significant cycles of approximately 24.8 hours at this site. Previously published 24-hour daily mean values may contain cycles that were a result of the 24-hour averaging and are unrelated to stream hydrology. October 2005 to current year, tidal effects were removed from unit value discharges using the Godin filter. Daily mean discharge computed from filtered values. Unit values available upon request.
For water year 2014: Records fair.
For water year 2015: Records fair.
For water year 2016: Records good.
For water year 2017: Records fair.
For water year 2018: Records fair.
For water year 2019: Records good to fair.
