USGS Water-Year Summary 2023

285531082412600 CRYSTAL RIVER AT MOUTH NEAR SHELL ISLAND NEAR CRYSTAL RIVER, FL.

LOCATION - Lat 28°55'31", long 82°41'26.3" referenced to North American Datum of 1983, in SW 1/4 SW 1/4 NE 1/4 sec.009, T.18 S., R.1 6., Citrus County, FL, Hydrologic Unit 03100207, (Red Level quadrangle), on green channel marker #23 on northeast side of Shell Island.

DRAINAGE AREA - Indeterminate.

REVISIONS HISTORY - WDR-US-2010:Water level data previously published at unknown datum for period of Oct. 7, 2006 through Sep. 30, 2009. Data revised at North American Vertical Datum of 1988 in 2010 water year for period of record. Period of record maximum and minimum gage heights published in error in WDR-US-2009.

SURFACE-WATER RECORDS

PERIOD OF RECORD - October 2006 to September 2010 (tidal high-high and low-low gage heights only); October 2010 to current year (maximum and minimum gage heights only).

GAGE - Datum of gage is at 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, 8.22 ft, Aug. 30, 2023; minimum gage height, 3.48 ft below NAVD 88, Jan. 3, 2008.

WATER-QUALITY RECORDS

PERIOD OF RECORD - October 2006 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 surface, in the middle, and near the bottom of the river. Top sensor elevation is 2.3 ft below North American Vertical Datum of 1988. Middle sensor elevation is 3.2 ft below NAVD 88. Bottom sensor elevation is 4.9 ft below NAVD 88.

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

EXTREMES FOR PERIOD OF RECORD - SPECIFIC CONDUCTANCE: Top sensor maximum, 48,800 microsiemens, Oct. 3, 2007; middle sensor maximum, 50,300 microsiemens, Oct. 3, 2007; bottom sensor maximum, 50,100 microsiemens, Oct. 3, 2007; top sensor minimum, 1,781 microsiemens, Aug. 04, 2021; middle sensor minimum, 1,771 microsiemens, Aug. 04, 2021; bottom sensor minimum, 1,773 microsiemens, Aug. 04, 2021. TEMPERATURE: Top sensor maximum, 33.8 °C, Aug. 14, 2023; middle sensor maximum, 33.9 °C, Aug. 14, 2023; bottom sensor maximum, 33.8 °C, Aug. 4, 2011, Aug. 14, 2023; top sensor minimum, 5.4 °C, Jan. 11, 12, 2010; middle sensor minimum, 5.5 °C, Jan. 11, 12, 2010; bottom sensor minimum, 5.5 °C, Jan. 12, 2010.
