USGS Water-Year Summary 2021
02310663 CHASSAHOWITZKA RIVER NEAR CHASSSAHOWITZKA, FL.
LOCATION - Lat 28°42'54", long 82°36'23" referenced to North American Datum of 1927, in SE 1/4 sec.28, T.20 S., R.17 E., Citrus County, FL, Hydrologic Unit 03100207, on private dock, on right edge of water, 0.3 mi upstream from confluence with Johnson Creek, and 2.0 mi west of Chassahowitzka.
DRAINAGE AREA - 76 mi².
REVISIONS HISTORY - WDR-04-3A:2003, 2004 (M and daily).
SURFACE-WATER RECORDS
PERIOD OF RECORD - May 1997 to September 1998 (gage heights only); May 2003 to September 2005 (daily values for discharge only); October 2005 to current year. May 1997 to September 1998 gage was published as 284254082362300 Chassahowitzka River above Johnson Creek nr Chassahowitzka, Fl.
GAGE - Water-stage and velocity sensors. Datum of gage is National Geodetic Vertical Datum of 1929 and 0.71 ft. below North American Vertical Datum of 1988.
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 a combination of freshwater and water storage caused by higher or lower Gulf of Mexico mean water levels. The residual discharge is used to estimate mean daily 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, 6.51 ft, Sept. 2, 2016; minimum, 2.40 ft below NGVD 29, Sept. 4, 2004.
WATER-QUALITY RECORDS
PERIOD OF RECORD - May 2003 to current year.
COOPERATION - This gage is monitored in cooperation with Southwest Florida Water Management District.
INSTRUMENTATION - Water-quality monitor consisting of a specific conductance and temperature sensors positioned approximately 3.5 ft below National Geodetic Vertical Datum of 1929.
EXTREMES FOR PERIOD OF RECORD - SPECIFIC CONDUCTANCE: Maximum, 38,000 microsiemens, June 30, 2009; minimum, 1,310 microsiemens, Aug. 17, 2019. TEMPERATURE: Maximum, 33.6°C, July 09, 2016; minimum, 8.7°C, Jan. 12, 2010.
