USGS Water-Year Summary 2024

02297460 PEACE RIVER AT HARBOUR HEIGHTS, FL.

LOCATION - Lat 26°59'14", long 81°59'40" referenced to North American Datum of 1927, in sec.22, T.40 S., R.23 E., Charlotte County, FL, Hydrologic Unit 03100101, on right bank, on private dock on Voyageur Road, 0.6 mi southeast of Harbour Heights, and 10.2 mi upstream from mouth.

DRAINAGE AREA - 1,870 mi².

REVISIONS HISTORY -

Bottom Specific Conductance data for the period of July 5^th 2018 to August 27^th 2018, were revised on March 3^rd 2019, due to a calibration correction needing to be applied.

Bottom specific Conductance data for the period of November 11^th 2018 to January 30^th 2019 , were revised on March 3^rd 2019, due to a negative fouling correction being applied that needed to be removed.

SURFACE-WATER RECORDS

PERIOD OF RECORD - August 1996 to September 2003 (gage heights only); October 2003 to September 2010 (tidal high-high and low-low gage heights only); October 2010 to current year (maximum and minimum gage heights only). Records of gage heights prior to October 1996 are available in files of the Geological Survey.

GAGE - Water-stage recorder. Datum of gage is National Geodetic Vertical Datum of 1929.

COOPERATION - This gage is monitored in cooperation with the Peace River/Manasota Regional Water Supply Authority.

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, 5.64 ft, Sep. 14, 2001; minimum, 2.46 ft below NGVD 29, Jan. 15, 2000.

WATER-QUALITY RECORDS

PERIOD OF RECORD -

August 1996 to current year, incomplete. Records of specific conductance and temperature prior to October 1996 are available in files of the Geological Survey.

COOPERATION - This gage is monitored in cooperation with the Peace River/Manasota Regional Water Supply Authority.

INSTRUMENTATION - Water-quality monitor consisting of specific conductance and temperature sensors located 3.2 ft below National Geodetic Vertical Datum of 1929, and 4.3 ft below National Geodetic Vertical Datum of 1929. Prior to Jan. 27, 2010 sensors located 0.4 and 3.5 below NGVD 29. Prior to Jan. 11, 2005 sensors located 1.0 ft below the surface and 1.0 ft above the bottom.

REMARKS - Top sensor comes out of water at times during extreme low tides.

EXTREMES FOR PERIOD OF RECORD - SPECIFIC CONDUCTANCE: Top sensor maximum, 47,000 microsiemens, June 2, 2007; bottom sensor maximum, 49,000 microsiemens, June 2, 2007; top sensor minimum, 71 microsiemens, Sept. 10, 2017; bottom sensor minimum, 62 microsiemens, Oct. 3, 2022. TEMPERATURE: Top sensor maximum, 36.6°C, Aug. 7, 2023; bottom sensor maximum, 35.7°C, July 29, 1998; top sensor minimum, 7.8°C, Jan. 25, 2003; bottom sensor minimum, 4.4°C, Jan. 3, 2008.
