USGS Water-Year Summary 2024

02280500 HILLSBORO CANAL BELOW S-351, NEAR SOUTH BAY, FL

LOCATION - Lat 26°42'00", long 80°42'45" referenced to North American Datum of 1927, in SW 1/4 sec.35, T.43 S., R.36 E., Palm Beach County, FL, Hydrologic Unit 03090202, acoustic Doppler velocity meter located approximately 1,800 ft downstream from S-351 and pump station 2 at Lake Okeechobee, and 2.5 mi north of South Bay, along the south bank of Hillsboro Canal.

DRAINAGE AREA - Indeterminate.

REVISIONS HISTORY - WDR FL-92-2A, 1991; WDR FL-03-2A, 2002.

SURFACE-WATER RECORDS

PERIOD OF RECORD - March 1957 to current year.

GAGE - Satellite data collection platform with water-stage shaft encoder and acoustic Doppler velocity meter. Prior to January 1, 2002, acoustic Doppler velocity meter. Prior to April 1993 electromagnetic velocity meter and digital water-stage recorder. Satellite data collection platform with water-stage shaft encoder and acoustic velocity meter installed December 1990. Prior to October 1, 1986, water-stage recorder at pump station 2 used for gage heights at this station. Prior to August 1982, deflection meter. Datum of gage is National Geodetic Vertical Datum of 1929 (U.S. Army Corps of Engineers benchmark).

REMARKS - Flow regulated by vertical lift gates and pump station at Lake Okeechobee. Flow frequently reversed during and after periods of heavy rainfall by pumpage into the canal from agricultural lands in the Everglades, by the operation of pump station 2, or by gravity flow through gates during periods of negative head (negative figures indicate flow reversed). Discharge computed from continuous velocity record obtained from acoustic doppler velocity meter starting January 1, 2002.

EXTREMES FOR PERIOD OF RECORD - Maximum gage height, 14.09 ft Sept. 28, 1962; minimum, 6.98 ft Oct. 28, 1981.
