USGS Water-Year Summary 2019
02310678 HOMOSASSA SPRINGS AT HOMOSASSA SPRINGS, FL.
LOCATION - Lat 28°47'58", long 82°35'20" referenced to North American Datum of 1927, Citrus County, FL, Hydrologic Unit 03100207, approximately 600 ft upstream of bridge on nature trail in Homosassa Springs, 0.8 mi west of town of Homosassa Springs, and 3.1 mi northeast of Homosassa.
SURFACE-WATER RECORDS
PERIOD OF RECORD - 1931-33, 1936, 1956, 1961, 1963-65 (miscellaneous discharge measurements); August 1965 to September 1978, June 1988 to March 1989 (discharge measurements only); October 1995 to current year.
GAGE - Water-stage recorder. Datum of gage is 2.99 ft below the North American Vertical Datum of 1988. Prior to Feb. 19, 2009, at datum 0.22 ft higher.
COOPERATION - This gage is monitored in cooperation with Southwest Florida Water Management District.
REMARKS - Streamflow at this site is significantly affected by astronomical tides. Discharge computed from relation between artesian pressure at Weeki Wachee Well near Weeki Wachee, spring-pool stage, and discharge at measuring site. Discharge was not filtered for tidal affect. See WRIR 01-4230 for computation techniques. 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, 7.86 ft, Sept. 02, 2016; minimum gage height, 0.76 ft, Jan. 03, 2008.
WATER-QUALITY RECORDS
PERIOD OF RECORD -

Temperature and specific conductance, June 2004 to current year. 

Nitrate, September 2015 to current year.

COOPERATION - This gage is monitored in cooperation with Southwest Florida Water Management District.
INSTRUMENTATION - Water-quality monitor consisting of specific conductance, temperature, and nitrate sensors. Water quality sensors mounted at an elevation of 0.1 ft. below NAVD 88. 
EXTREMES FOR PERIOD OF RECORD - SPECIFIC CONDUCTANCE:Maximum, 22,800 microsiemens, (partial day) Sept. 02, 2016; minimum, 1,160 microsiemens, Sept. 27, 2004. TEMPERATURE:Maximum, 28.5°C, June 07, 2016; minimum, 21.7°C (partial day), Jan. 17, 2009. NITRATE: Maximum, 0.83 mg/l, several days; minimum, 0.38 mg/l, October 10, 2018.
