USGS Water-Year Summary 2023

02129000 PEE DEE RIVER NEAR ROCKINGHAM, NC

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 Duke Energy Progress 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.

SURFACE-WATER RECORDS

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. 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. Satellite telemetry at streamgage.

REMARKS -

Flow regulated since 1928 by Blewett Falls Lake and five other reservoirs upstream.
Gage-height records are generally good. Discharge records are generally fair 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-nc_nwisweb_data_inquiries@usgs.gov.

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.
