DRAINAGE AREA - 119 mi².
SURFACE-WATER RECORDS
PERIOD OF RECORD - October 2005 to September 2010 (tidal high-high and low-low gage heights only); October 2010 to current year (maximum and minimum gage heights only).
GAGE - Water-stage recorder. Datum of gage is North American Vertical Datum of 1988.
COOPERATION - This gage is monitored in cooperation with Southwest Florida Water Management District.
REMARKS - Gage height at this site is significantly affected by astronomical tides. The extremes for periods published previously as tidal high-high and low-low gage heights are equivalent to maximum and minimum gage heights.
EXTREMES FOR PERIOD OF RECORD - Maximum gage height, 6.58 ft Sept. 02, 2016; minimum, 3.54 ft below NAVD 88, Jan. 3, 2008.
WATER-QUALITY RECORDS
PERIOD OF RECORD - June 2005 to current year.
COOPERATION - This gage is monitored in cooperation with Southwest Florida Water Management District.
INSTRUMENTATION - Water-quality monitor consisting of specific conductance and temperature sensors located near the top and above the bottom. Top sensor elevation is 2.8 ft below NAVD 88. Bottom sensor elevation is 6.2 ft below NAVD 88.
EXTREMES FOR PERIOD OF RECORD - SPECIFIC CONDUCTANCE:Top sensor maximum, 41,800 microsiemens, June 30, 2009; bottom sensor maximum, 42,400 microsiemens, June 30, 2009; top sensor minimum 2,080 microsiemens, Aug. 18, 2019; bottom sensor minimum, 2,160 microsiemens, Aug. 18, 2019. TEMPERATURE:Top sensor maximum 34.1°C, June 16, 2010, July 08, 2016; bottom sensor maximum, 34.2 °C, July 08, 2016; top sensor minimum, 5.8°C, Jan. 12, 2010; bottom sensor minimum, 5.8 °C, Jan. 12, 2010.
