  • Due to a lapse in appropriations, the majority of USGS websites may not be up to date and may not reflect current conditions. Websites displaying real-time data, such as Earthquake and Water and information needed for public health and safety will be updated with limited support. Additionally, USGS will not be able to respond to inquiries until appropriations are enacted. For more information, please see www.doi.gov/shutdown.

Water-Year Summary for Site 02327033

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 2018
LOCATION - Lat 30°11'17", long 84°24'30" referenced to North American Datum of 1927, in sec.26, T.3 S., R.2 W., Wakulla County, FL, Hydrologic Unit 03120001, on downstream side of bridge on State Highway 368, and 0.5 mi east of Arran.
DRAINAGE AREA - 70.4 mi².
PERIOD OF RECORD - October 1998 to December 2005, January 2007 to July 2010, November 2014 to October 17, 2017.
GAGE - Water-stage recorder. Datum of gage is 11.08 ft above mean sea of 1929 NGVD.

Water-quality monitor measuring temperature, specific conductivity and FDOM installed September 25, 2015.  Period of record from September 25, 2015 to October 17, 2017.  Site discontinued on October 17, 2017.

Turbidity sensor installed on monitor on October 5, 2016.  Period of record from October 5, 2016 to October 17, 2017.  Site discontinued on October 17, 2017.

INSTRUMENTATION - YSI EXO2 water-quality monitor consisting of temperature, specific conductivity, FDOM and turbidity.
REMARKS - Extremes for current year and extremes for period of daily record are based on recorded values and may have been exceeded during periods of no record. September 2015 to October 2017, water temperature, specific conductance, and FDOM are published as instantaneous maximum and minimum, and daily mean. FDOM readings from this sensor have not been adjusted for potential interferences from turbidity and other constituents.
