SURFACE-WATER RECORDS

PERIOD OF RECORD - September 2006 to September 2009 (tidal high-high and low-low gage heights only); October 2014 to current year (maximum and minimum gage heights only).

GAGE - Water-stage recorder. Datum of gage is North American Vertical Datum of 1988. Prior to October 1, 2007 at datum of NGVD 1929.

COOPERATION - This gage is monitored in cooperation with Southwest Florida Water Management District.

REMARKS - 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, 7.95 ft. (high water mark), Aug. 30, 2023; minimum gage height, 3.16 ft. below NAVD 88, Jan. 3, 2008.

WATER-QUALITY RECORDS

PERIOD OF RECORD - September 2006 to September 2009 (top, middle, and bottom temperature and specific conductance sensors); October 2014 to current year (top and bottom temperature and specific conductance sensors).

COOPERATION - This gage is monitored in cooperation with Southwest Florida Water Management District.

INSTRUMENTATION - Water-quality monitor consisting of specific conductance and temperature sensors. The top sensor is approximately 3.1 ft below NAVD '88 and the bottom sensor is approximately 6.0 ft below NAVD '88.

EXTREMES FOR PERIOD OF RECORD - SPECIFIC CONDUCTANCE: Top sensor maximum, 49,900 microsiemens, June 3, 4, 2008; bottom sensor maximum, 49,600 microsiemens, Aug. 13, 2008; top sensor minimum, 5,730 microsiemens, Aug. 07, 2021; bottom sensor minimum, 5,640 microsiemens, Aug. 19, 2019. TEMPERATURE: Top sensor maximum, 34.6°C, Aug. 13, 2023; bottom sensor maximum, 34.7°C, Aug. 13, 2023; top sensor minimum, 6.3°C, Jan. 4, 2018; bottom sensor minimum, 6.1°C, Jan. 4, 2018.
