USGS Water-Year Summary 2023

02102500 CAPE FEAR RIVER AT LILLINGTON, NC

LOCATION - Lat 35°24'22", long 78°48'48" referenced to North American Datum of 1983, Harnett County, NC, Hydrologic Unit 03030004, on right bank 60 ft downstream of bridge on U.S. Highway 401, 1,860 ft downstream of Southern Railway bridge, 0.5 mi north of Lillington, 1 mi downstream of Neal Creek, and at river mile 178.

DRAINAGE AREA - 3,464 mi².

REVISIONS HISTORY - WSP 1002: 1930, maximum discharge. WSP 1032: 1942, minimum discharge. WSP 1303: 1944, maximum discharge. WSP 1333: 1945, maximum discharge. WSP 1383: 1924-29, maximum and minimum discharges; 1924-29, daily discharges; 1936, daily discharges. WSP 1703: 1929, daily discharges. WDR NC-81-1: Drainage area.

SURFACE-WATER RECORDS

PERIOD OF RECORD - Discharge, December 1923 to current year. Water quality, April 2021 to current year.

GAGE - Water-stage recorder. Satellite telemetry at streamgage. The datum of the gage is 103.6 ft above NAVD88 NAD83(2011). Satellite telemetry at streamgage.
Historical: Datum previously reported at 104.62 ft above NGVD of 1929. December 6, 1923 to October 7, 1927, nonrecording gage and October 8, 1927 to December 2, 1975, water-stage recorder at site 60 ft upstream at bridge pier at same datum.

REMARKS - Some regulation at high flows, December 1972 to August 1981, caused by temporary storage in B. Everett Jordan Lake. Flow regulated since September 1981 by B. Everett Jordan Lake (station 02098197). Diurnal fluctuation and slight regulation at low flow caused by power plants upstream from station. Fluctuation and regulation by Buckhorn Reservoir, 13 mi upstream from station, ended in December 1962.
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-nc_nwisweb_data_inquiries@usgs.gov.
