Water-year peak flow and stage data at gaging stations in 

South Carolina through 1999
A-2

The following tables contain flood data for streamflow gaging stations in South Carolina. 

The tables contain a brief description of the gage location, type of gage, gage datum (if known), 

drainage area in square miles, period of record, extreme flows of record, a description of how the 

stage-discharge relation was obtained, historical data, hydrologic unit number1, and explanatory 

remarks.

The log-Pearson Type III flood-frequency data using either a weighted or station skew 

coefficient, and adjusted for historic peaks, high and low outliers, and truncated or incomplete 

record, are given for most stations with 10 or more years of record.

The tables of peak stages, peak flows, and date of peaks show only the water-year maximums. Underlined data in these tables signify the following:

1. An underlined entry in the “Water year” column indicates discontinuous record.

2. An underlined entry in the “Gage height” column indicates a change in gage datum and 

means that the gage heights above and below the line are not comparable.

3. Underlined entries in the “Date” and “Discharge” columns indicate a change in the site 

location that significantly affects the stage-discharge relation.

[Lat, latitude; long, longitude; ft, feet; mi, mile; mi2, square miles; ft3/s, cubic feet per second; ---, 

data not available; a, peak stage occurred at a different time than peak discharge; b, historic peak; 

WSP, Water-Supply Paper]

Water year is the 12-month period beginning October 1 and ending on September 30 of any given 

year, and designated by the calendar year in which the water year ends. 

______________________________________________

1

 The hydrologic unit number is determined from a set of maps developed by the U.S. Geological Survey that depict the approved 

boundaries of river-basin units of the United States and documented in U.S. Geological Survey Water-Supply Paper 2294 by 

P.R. Seaber, F.P. Kapinos, and G.L. Knapp (1987). These maps and associated codes provide a standardized base for use by waterresources organizations in locating, storing, retrieving, and exchanging hydrologic data; indexing and inventorying of hydrologic data 

and information; cataloging of water-data acquisition activities; and a variety of other applications.

LOCATION.--Lat 34o50'32'', long 82o28'51'', Pickens County, Hydrologic Unit 03050109, on right bank 700 ft upstream from bridge 

on State Road 124, 1.6 mi downstream from Saluda Lake Dam, 2.4 mi upstream from Georges Creek, 4.6 mi west of City Hall in 

Greenville, and at mile 132.0.

DRAINAGE AREA.--295 mi2.

PERIOD OF RECORD.--January 1942 to September 1978, October 1980 to current year.

GAGE.--Water-stage recorder until 1978, crest-stage partial-record station from October 1980 to January 1990, and data collection 

platform from February 1990 to current year. Elevation of gage is 797.48 ft above sea level. 

REMARKS.--Some regulation at low and medium flow by the power plant at Saluda Lake. Capacity of reservoirs insufficient to 

affect monthly figures of runoff. Some flow is diverted above station for City of Greenville water supply during water year. City of 

Greenville began diverting water from Saluda River (Table Rock Reservoir) in 1930; supplemented by North Saluda Reservoir in 

1961.

EXTREMES FOR PERIOD OF RECORD.--Maximum discharge, 11,000 ft3/s, Oct. 7, 1949, gage height, 19.38 ft.

STAGE-DISCHARGE RELATION.--Defined by current-meter measurements below 7,540 ft3/s and extended on basis of computation of peak flow over the dam at Saluda Lake.
