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 2022
LOCATION - Lat 29°12'14", long 82°46'09" referenced to North American Datum of 1927, in SW 1/4 sec.02, T.15 S., R.15 E., Levy County, FL, Hydrologic Unit 03110101, near left bank at abandoned railroad grade, 0.5 mi upstream of Otter Creek, 3.6 mi upstream of mouth, 4 mi southwest of Gulf Hammock.
DRAINAGE AREA - 480 mi².
REVISIONS HISTORY - WSP 2105: 1969. WRD FL-72-1: Drainage area. WRD FL-04-4:2003. Discharge for the period of May 6, 2003 to Oct 24, 2013, was revised on Dec. 7, 2018, based on changes to the stage area and index velocity ratings.
PERIOD OF RECORD - March 1963 to September 1978, November 1980 to September 1984 (fragmentary), October 1984 to September 1992, October 1998 to September 2002, October 2002 to September 2003 (fragmentary), October 2003 to September 2009, October 2009 to current year (filtered).
GAGE - Water-stage recorder, acoustic velocity meter, and data-collection platform. Datum of gage is 10.51 ft below National Geodetic Vertical Datum of 1929 and 11.29 ft below NAVD of 1988. Prior to Nov. 24, 1980, water-stage and deflection-meter recorders at same site at datum 10.00 ft higher.
COOPERATION - This gage is monitored in cooperation with the Suwannee River Water Management District.
REMARKS - Discharge not published some days, due to bad or missing gage-height or velocity data. Streamflow at this site is significantly affected by astronomical tides. Daily mean discharge was computed from filtered unit value discharge data. The Godin low-pass filter was used to remove principal tidal frequencies from unit values. By convention, the U.S. Geological Survey has established ebb (seaward) flows as positive flow and flood (landward) flows as negative flows. The residuals are not total freshwater flows but are a combination of freshwater flows and water storage caused by higher and lower mean sea levels and storm surges from tropical storm events. Instantaneous discharge computed from index-velocity linear regression relation and gage height rating. Daily values of discharge and gage-height are available online at http://waterdata.usgs.gov/nwis.

Records include flow of Otter Creek. Above bankfull stage, discharge measurements are made along abandoned railroad fill and include all flow from about 1.5 mi northwest to 0.8 mi northeast of gaging station. Drainage Area: Including that of Otter Creek.

SPECIFIC CONDUCTANCE: September 2018 to current year. 

WATER TEMPERATURE: September 2018 to current year.

DISSOLVED OXYGEN: September 2018 to current year.
