Water-year peak-flow and stage data at gaging stations in South Carolina on regulated streams and 

on streams draining more than one physiographic province through 1999
D-2

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

are regulated and (or) drain more than one physiographic province. 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 are given for unregulated sites that drain 

more than one physiographic province 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 and discharges show only the annual 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.

/s, cubic feet per second; ---, 

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

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.

Engineers, at site 200 ft upstream, at different datum.

REMARKS.--Discharge records for 1987-99 water years are computed by utilization of a one-dimensional unsteady flow simulation 

model (BRANCH). Flow completely regulated by Lake Marion. Water is diverted above station from Lake Marion through Diversion 

Canal into Lake Moultrie for generation of power and for navigation, then discharged into Cooper River basin and lower Santee.

EXTREMES FOR PERIOD OF RECORD.--Maximum discharge 155,000 ft3

/s, Sept. 23, 1945, gage height, 31.1 ft (from flood 

marks).

STAGE-DISCHARGE RELATION.--Defined by current-meter measurements below 14,600 ft3/s and extended by computation of 

peak flow over spillway at Lake Marion.

FLOOD-FREQUENCY DATA.--Frequency analysis not performed on Santee River near Pineville, S.C., because of regulation. The 

regulation pattern has been altered since rediversion in 1986.

Fifth Street gage), marked by local residents; discharge approximately 360,000 ft3/s, by slope conveyance study. Little information 

exists and the data are considered approximate. Data furnished by the U.S. Army Corps of Engineers.

STAGE-DISCHARGE RELATION.--Defined for period prior to levee construction (completed in 1914) by current-meter 

measurements below 127,000 ft3/s and by slope-conveyance study at 360,000 ft3/s. Defined for subsequent period by current-meter 

measurements below 300,000 ft3

/s and by computation of flow over Stevens Creek Dam to 350,000 ft3/s. Bankfull stage and 

discharge, 21 ft and 36,000 ft3

/s. At site used prior to Oct. 1, 1936, bankfull stage and discharge, 32 ft and approximately 

110,000 ft3/s.

FLOOD FREQUENCY DATA.--The flood-frequency relation for this station was computed by routing pre-regulation hydrographs 

through the existing system of reservoirs using the methodology described by Sanders and others (1990). Interested individuals

should consult this reference for further frequency information at this site.
