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 2020
LOCATION - Lat 29°50'55", long 82°42'55" referenced to North American Datum of 1927, in SE 1/4 sec.28, T.7 S., R.16 E., Gilchrist County, FL, Hydrologic Unit 03110206, on left bank 2.1 mi upstream from bridge on State Highway 47, 5.1 mi south of Fort White, and 18 mi upstream from mouth.
DRAINAGE AREA - 1,017 mi².
REVISIONS HISTORY - WDR FL-75-1: Drainage area.
PERIOD OF RECORD - October 1927 to January 1930, June 1932 to current year.
GAGE - Water-stage recorder and data-collection platform. Datum of gage is 20.86 ft above National Geodetic Vertical Datum of 1929 (levels by Corps of Engineers)and 20.06 ft above North American Vertical Datum of 1988. Prior to June 3, 1932, nonrecording gage at several sites within 200 ft of present site at various datums. Oct. 1, 1947 to Feb. 10, 1949, auxiliary nonrecording gage and since Feb. 11, 1949, auxiliary water-stage recorder at bridge on U.S. Highway 129, 16 mi downstream from base gage at datum 3.5 ft above National Geodetic Vertical Datum of 1929.
PERIOD OF RECORD - Water-quality monitor installed August 22, 2015.  Period of record from August 22, 2017 to current year.
