  • UPDATE, 11/9: As of November 8, the USGS has successfully restored all of the operational gages that stopped transmitting due to an issue with the satellite telemetry system that records and transmits data. The USGS will now focus on restoring other equipment that experienced the telemetry issues, including about 85 rapid deployment gages that are used periodically for emergency response. Read more

USGS Water-Year Summary 2018
LOCATION - Lat 28°19'30", long 81°31'15" referenced to North American Datum of 1927, in SW 1/4 sec.09, T.25 S., R.28 E., Osceola County, FL, Hydrologic Unit 03090101, on upstream side of sheet-pile weir, about 0.5 mi upstream from Reedy Creek Swamp, and 5.0 mi south of Vineland.
DRAINAGE AREA - 44.7 mi².
REVISIONS HISTORY - WDR FL-96-1A: Drainage area.
PERIOD OF RECORD - Water years 1943, 1960, 1961, 1966 (miscellaneous discharge measurements), May 1966 to current year.
GAGE - Water-stage recorder, steel sheet-pile weir with sluice gate, water quality monitor, and data-collection platform. Datum of gage is at NGVD of 1929 (Florida Department of Transportation bench mark). Prior to June 1, 1999, at site 0.5 mi upstream at same datum; prior to Oct. 1, 1968, at datum 37.96 ft higher.
COOPERATION - This gage is monitored in cooperation with the Reedy Creek Improvement District.
REMARKS - Since October 1968, flow regulated by automatic gates upstream and since December 1970, by control structure S-11. Natural flow of stream affected by canals and control structures above station which divert an undetermined amount of water into the Reedy Creek basin. From Oct. 13, 1983 to Feb. 1, 1985 structure S-11 did not regulate the stream because of a washout of the bank around the structure.
EXTREMES OUTSIDE PERIOD OF RECORD - Flood of Sept. 11, 1960, reached a stage of 42.5 ft, datum then in use, from floodmarks, discharge, 1,200 ft³/s.
PERIOD OF RECORD - Water years 1961, 1963, 1966, 1968-94, 1996 to 2007, 2009.
SPECIFIC CONDUCTANCE: July 2001 to September 2011, November 2012 to current year.
WATER TEMPERATURE:    July 2001 to September 2011, November 2012 to current year.
DISSOLVED OXYGEN:     July 2001 to September 2011, November 2012 to current year.
REMARKS - Extremes for current year and extremes for period of daily record are based on recorded values and may have been exceeded during periods of no record. July 2001 to September 2008, published as daily mean; October 2008 to September 2011, October 2012 to September 2014, published as instantaneous maximum and minimum. October 2014 to current year; water temperature, specific conductance, and dissolved oxygen published as instantaneous maximum, instantaneous minimum, and daily mean. Due to extreme low water levels and conditions of no flow, no data collected 2012 water year.

SPECIFIC CONDUCTANCE: Maximum, 375 µS/cm @ 25 °C, Sept. 17, 2016; minimum, 87 µS/cm @ 25 °C, Aug. 24, 2003; maximum daily mean, 341 µS/cm @ 25 °C, June 4, 2017; minimum daily mean, 91 µS/cm @ 25 °C, Aug. 26, 2003.

WATER TEMPERATURE: Maximum, 36.2 °C, July 27, 2010; minimum, 8.5 °C, Jan. 12, 2010; maximum daily mean, 31.5 °C, Aug. 21, 2016, July 1, 2015, minimum daily mean, 11.7 °C, Jan. 25, 2003.

DISSOLVED OXYGEN: Maximum, 16.8 mg/L, May 27, 28, 2013; minimum, 0.0 mg/L, many days; maximum daily mean, 10.4 mg/L, Mar. 8, 9, 2002; minimum daily mean, 0.0 mg/L, many days 2007, May 8, 9, 2008.
