Water-Year
Summary
instructions
and
information
- Water-Year Summary reports summarize a year of hydrologic data in a printer-friendly format.
- For water years 2014 onward, choose a water year and parameter and an on-demand Water-Year Summary report will be generated.
- For water years 2006 through 2013, choose a water year and an Annual Water Data Report will be provided.
- For water years 2005 and earlier, Annual Water Data Reports may be available in digital format.
- Not all sites have reports available for every water year.
USGS Water-Year Summary 2024
02094659 SOUTH BUFFALO CREEK NEAR POMONA, NC
LOCATION - Lat 36°02'58", long 79°51'19" referenced to North American Datum of 1983, Guilford County, NC, Hydrologic Unit 03030002, on right bank 300 ft upstream from culvert at Merritt Road, 0.7 mi south of Pomona, and 1.0 mi downstream from Southern Railway bridge.
DRAINAGE AREA - 7.33 mi².
REVISIONS HISTORY - WDR NC-03-1B: 1999-02 (annual maximum discharge). WDR NC-04-1: 2003(annual maximum gage height).
Data was revised from May 21, 2016 to August 2, 2018 due to a datum correction by levels.
Data was revised from September 9, 2020 to February 23, 2021 due to a datum correction by levels. Primary reference readings, discharge measurements, and rating shifts were all edited to correspond with the datum correction
PRECIPITATION: Data from May 24, 2016 to January 2017 were unlocked and all precipitation data from May 24, 2016 to October 25, 2017 were deleted. All calibrations after May 24, 2016 failed calibration by more than 10% during this period. Data was deleted as per OSW TM 2006.01

SURFACE-WATER RECORDS
PERIOD OF RECORD - June 1999 to current year.
GAGE - Water-stage recorder. Datum of gage is 771.84 ft above National Geodetic Vertical Datum of 1929. Satellite telemetry at streamgage.
REMARKS - 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 discharge for period of record, 3350 ft³/s, September 23, 2003, from rating curve extended above 500 ft³/s on basis of culvert computation of peak flow; Maximum gage height 15.45 ft. September 23, 2003. Minimum daily mean discharge, 0.07 ft³/s (estimated).
CLIMATOLOGICAL RECORDS
PERIOD OF RECORD - January 2000 to current year.
INSTRUMENTATION - Tipping-bucket raingage. Satellite telemetry at station.
REMARKS - Precipitation collected during freezing periods may not be accurately reflected in the daily record.
