USGS Water-Year Summary 2023
0211139110 YADKIN RIVER BELOW W. KERR SCOTT DAM NEAR BUCK, NC
LOCATION - Lat 36°08'10", long 81°13'24" referenced to North American Datum of 1983, Wilkes County, NC, Hydrologic Unit 03040101, Lat 36 08'10", long 81 13'24", Wilkes County, Hydrologic Unit 03040101, on right bank 500 ft downstream of W Kerr Scott Reservoir spillway in northeast corner of parking lot off of Old NC 268 (Ranger Rd), 5.5 miles upstream from Reddies River, 3.5 mi southwest of Wilkesboro.
DRAINAGE AREA - 367 mi².
REVISIONS HISTORY - Gage datum was revised on October 28, 2021, based on an error in the determination of the gage datum.
SURFACE-WATER RECORDS
PERIOD OF RECORD - November 2007 to current year.
GAGE - Water-stage recorder and crest-stage gage. Datum of gage is 961.67 ft above North American Vertical Datum of 1988. Satellite telemetry at streamgage.
REMARKS -

Considerable regulation caused by W. Kerr Scott Reservoir 500 ft. 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 - Maximum instantaneous discharge, 5820 cfs, Feb 14, 2008. Maximum instantaneous gage height, 9.28 ft, Feb 14, 2008. Minimum daily mean discharge, 73.1 cfs, May 17, 2018, during normal regulation. There were two periods during the 2018 Water Year, June and July, when there were extreme circumstances which caused regulation to fall below current rating and a Minimum Daily mean discharge could not be determined. There was one period in the 2019 water year, 10 Apr 2019, when dam was closed for maintenance causing gage height to fall below current rating and discharge was estimated based on measurements taken at this time. Gage height was 0.16 ft and estimated discharge was 1.92 cfs.
