USGS Water-Year Summary 2024

250802081035500 EAST SIDE CREEK NEAR LAKE INGRAHAM, FL

LOCATION - Lat 25°08'13.09", long 81°03'51.77" referenced to North American Datum of 1983, Monroe County, FL, Hydrologic Unit 03090203, located on left bank, 0.5 mi upstream of creek mouth, 8 mi west of Flamingo.

DRAINAGE AREA - Indeterminate.

SURFACE-WATER RECORDS

PERIOD OF RECORD - February 2009 to current year.

GAGE - Satellite data collection platform with acoustic stage transducer and acoustic Doppler velocity meter. Datum of gage is North American Vertical Datum of 1988 (NAVD 88).

REMARKS - Streamflow at this site significantly affected by astronomical tides. Daily mean discharge computed from filtered unit value discharge data. The Godin low-pass filter used to remove principal tidal frequencies from unit values. Positive flow (ebb tide) is generally to the south direction and negative discharge (flood tide) to the north. Discharge and gage height records, are available in files of the U.S. Geological Survey. Discharge and gage height 15 minute data can also be accessed online at http://sofia.usgs.gov/. Daily values are available online at http://waterdata.usgs.gov/nwis.

EXTREMES FOR PERIOD OF RECORD - DISCHARGE: Maximum positive discharge, 2,958 ft³/s (unfiltered) Sept. 29, 2022; maximum negative, 3,140 ft³/s (unfiltered) Sept. 28, 2022. GAGE HEIGHT: Maximum gage height, 4.98 ft Sept. 10, 2017; minimum, -3.40 ft Mar. 08, 2020.

WATER-QUALITY RECORDS

PERIOD OF RECORD - SALINITY: February 2009 to current year. SPECIFIC CONDUCTANCE: February 2009 to current year. WATER TEMPERATURE: February 2009 to current year. TURBIDITY: February 2009 to current year.

INSTRUMENTATION - Multi-parameter water quality monitor.

REMARKS - Salinity computed from specific conductance data. Salinity, water temperature, and turbidity records available in files of the U.S. Geological Survey. Salinity, water temperature, and turbidity 15 minute data accessible online at http://sofia.usgs.gov/. Daily values of salinity, water temperature, and turbidity available online at http://waterdata.usgs.gov/nwis.

EXTREMES FOR PERIOD OF RECORD - SALINITY: Maximum recorded, 55.0 ppt June 14, 2011, May 20, 2017; minimum recorded, 14 ppt Nov. 18, 19, 20, 2020.
SPECIFIC CONDUCTANCE: Maximum recorded, 78,700 uS/cm @ 25°C June 14, 2011, May 20, 2017; minimum recorded, 22,400 uS/cm @ 25°C Nov. 20, 2020.
WATER TEMPERATURE: Maximum recorded, 37.3°C July 12, 2016; minimum recorded, 4.8°C Jan. 11, 2010.
TURBIDITY: Maximum recorded,1,000 FNU Sept. 10, 2017 (exceeds equipment specifications or greater than qualifier), minimum recorded, 0.4 FNU Oct. 28, 2011.
