USGS Water-Year Summary 2021
LOCATION - Lat 34°56'45", long 79°52'11" referenced to North American Datum of 1983, Richmond County, NC, Hydrologic Unit 03040201, on left bank at U.S. Highway 74 West bridge, 2.5 mi upstream from Falling Creek, 3.3 mi downstream from Progress Energy Blewett Falls Hydroelectric Plant, 6 mi west of Rockingham, and 192 miles upstream from mouth in Winyah Bay.
DRAINAGE AREA - 6,863 mi².
REVISIONS HISTORY - WSP 1203: 1928-37, daily discharges; 1928-50, minimum discharge. WSP 1303: 1928-37, monthly and yearly mean discharges: 1943-46, adjusted monthly runoff, unreliable. WSP 1503: 1906-12, daily discharges; 1928-32, minimum discharges, unreliable. WDR NC-80-1: Drainage area.
PERIOD OF RECORD - August 1906 to January 1912, October 1927 to current year. August 1906 to January 1912 published as "Yadkin River near Pee Dee".
GAGE - Water-stage recorder. Datum of gage is 119.52 ft above North American Vertical Datum of 1988 (from Trimble GPS). August 1906 to January 1912 nonrecording gage at site 3.3 mi upstream at different datum. September 1927 to September 30, 1931, water-stage recorder at present site at 121.68 ft. above National Geodetic Vertical Datum of 1929. Telephone and satellite telemetry at streamgage.
REMARKS - Flow regulated since 1928 by Blewett Falls Lake and five other reservoirs upstream.
For Water Year 2014: Records good except those below 1,000 ft³/s, which are fair.
For Water Year 2015: Records good except those below 1,000 ft³/s, which are fair.
For Water Year 2016: Records good.
For Water Year 2017: Records good.
For Water Year 2018: Records good.
For Water Year 2019: Records fair.
EXTREMES FOR PERIOD OF RECORD - Minimum daily discharge for period of record: 58 ft³/s, December 2, 1951, a result of abnormally low flow during shutdown of Blewett Falls hydroelectric plant to produce steady flow for current-meter measurements at this gaging station.
EXTREMES FOR PERIOD PRIOR TO REGULATION - Prior to regulation, maximum discharge: 276,000 ft³/s, August 27, 1908; gage height: 31.28 ft, at present site and datum, from records of State Highway Commission. Prior to regulation, minimum discharge: 2,210 ft³/s, September 3, 1907.
