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
LOCATION - Lat 29°40'09", long 81°15'35" referenced to North American Datum of 1927, in sec.45, T.10 S., R.30 E., St. Johns County, FL, Hydrologic Unit 03080201, in land grant 45, on left bank, at Faver-Dykes State Park, 1.5 mi upstream from mouth, 1.8 mi east of intersection of U.S. Highway 1 and Interstate Highway 95, and 13 mi northeast of Espanola.
DRAINAGE AREA - Indeterminate.
PERIOD OF RECORD - December 2001 to September 2010, October 2010 to September 2013, March 2017 to current year (filtered).
GAGE - Water-stage recorder, acoustic velocity meter, and data-collection platform. Datum of gage is 13.65 ft above NGVD of 1929 and 14.53 ft above NAVD of 1988.
COOPERATION - This gage is monitored in cooperation with the St. Johns 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.
