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.

01627500 SOUTH RIVER AT HARRISTON, VA
LOCATION - Lat 38°13'07", long 78°50'13" referenced to North American Datum of 1927, Augusta County, VA, Hydrologic Unit 02070005, on left bank 200 ft downstream from bridge on State Highway 778, 0.3 mi northwest of Harriston, 0.6 mi downstream from Paine Run, and 7.2 mi upstream from confluence with North River.
DRAINAGE AREA - 212 mi².
REVISIONS HISTORY - WSP 1171: 1926(M), 1927-28, 1929-32(M), 1933, 1934(M), 1935, 1937. WSP 1302: 1937(M), 1938(M). WSP 2103: Drainage area.
SURFACE-WATER RECORDS
PERIOD OF RECORD - February 1925 to September 1951, October 1968 to current year.
GAGE - Water-stage recorder. Datum of gage is 1,129.15 (±0.1) ft above NAVD 88. Prior to Sept. 1, 1938, nonrecording gage at present site and datum.
COOPERATION - Records were provided by the Virginia Department of Environmental Quality - Water Division.
REMARKS - There are discharges from industrial and municipal wastewater treatment plants upstream from station, originating from well fields. Maximum discharge, 28,900 ft³/s, from rating curve extended above 10,000 ft³/s on basis of slope-area measurement at gage height 15.47 ft.
EXTREMES OUTSIDE PERIOD OF RECORD - Floods in 1870 and 1877 reached a stage of about 18.8 ft, from information by observer in 1925.
EXTREMES FOR PERIOD OF RECORD - Instantaneous low flow, 17 ft³/s, Nov. 14, 1941, probably result of regulation by mill then in existence upstream from station.
