Click to hide Water-Year Summary instructions and information
  • Water-Year Summary reports summarize a year of hydrologic data in a printer-friendly format.
  • For water years 2014 onward, choose a water year and parameter and an on-demand Water-Year Summary report will be generated.
  • For water years 2006 through 2013, choose a water year and an Annual Water Data Report will be provided.
  • For water years 2005 and earlier, Annual Water Data Reports may be available in digital format.
  • Not all sites have reports available for every water year.

USGS Water-Year Summary 2021
02310700 HOMOSASSA RIVER AT HOMOSASSA, FL.
LOCATION - Lat 28°47'06", long 82°37'05" referenced to North American Datum of 1927, in sec.31, T.19 S., R.17 E., Citrus County, FL, Hydrologic Unit 03100207, on left bank, on private dock, 0.3 mi northwest of Homosassa, and 5.3 mi upstream from mouth.
DRAINAGE AREA - Not determined.
REVISIONS HISTORY - WDR FL-05-3A:Residual discharge 2004 water year. WDR-US-2009:Datum of gage 2008 water year. WDR-US-2013:Revised figures of residual discharge for water year 2004 - 2011.
SURFACE-WATER RECORDS
PERIOD OF RECORD - January 1964 to September 1965 (gage heights and periodic discharge measurements only); October 1965 to September 1969 (periodic discharge measurements and maximum and minimum gage heights only); October 1969 to September 1976 (maximum and minimum gage heights only); October 1976 to September 1978 (maximum and minimum elevations only); March 1984 to May 1984 (gage heights only); June 1984 to November 1985; December 1985 to February 1986 (gage heights only); July 1997 to February 1999 (gage heights only); May 2004 to current year.
GAGE - Water-stage and velocity recorder. May 2004 to current datum of gage is 1.49 ft above National Geodetic Vertical Datum of 1929. Prior to Oct. 1976 datum of gage was 10 ft below NGVD 29. Oct. 1976 to Sept. 1977 datum of gage was NGVD 29. Oct. 1978 datum of gage was 10 ft below NGVD 29. March 1984 to Feb. 1999 datum of gage was NGVD 29. Gage heights have been reduced to datum of gage. July 1997 to February 1999, at site 500 ft upstream.
COOPERATION - This gage is monitored in cooperation with Southwest Florida Water Management District.
REMARKS - Streamflow at this site is significantly affected by astronomical tides. The residual discharges are not total "freshwater" flow, but are a combination of freshwater flow and water storage caused by higher or lower Gulf of Mexico mean water levels. The residual discharge is used to estimate mean discharge values. By convention, the U.S. Geological Survey has established ebb (seaward) flows as positive flow and flood (landward) flows as negative flows.
EXTREMES FOR PERIOD OF RECORD - Maximum gage height 4.41 ft above datum of gage, Sep. 2, 2016; minimum 3.29 ft below datum of gage, Jan. 3, 2008. Datum of gage is 1.49 ft above National Geodetic Vertical Datum of 1929.
WATER-QUALITY RECORDS
PERIOD OF RECORD - May 2004 to current year.
COOPERATION - This gage is monitored in cooperation with Southwest Florida Water Management District.
INSTRUMENTATION - Near top and near bottom water-quality monitors consisting of specific conductance and temperature sensors. Sensors located 2.30 ft and 6.10 ft below gage datum.
EXTREMES FOR PERIOD OF RECORD - SPECIFIC CONDUCTANCE: Top sensor maximum, 37,087 microsiemens, May 24, 2017; bottom sensor maximum, 36,313 microsiemens, January 23, 2017; top sensor minimum, 1,970 microsiemens, Aug. 18, 2019; bottom sensor minimum, 1,050 microsiemens, Aug. 8, 2003. TEMPERATURE: Top sensor maximum, 33.9°C, Aug. 17, 2010; bottom sensor maximum, 33.6°C, June 15, 2010, July 20, 2010; top sensor minimum, 9.2°C, Jan. 12, 2010; bottom sensor minimum, 9.2°C, Jan. 12, 2010.
