Water-Year Summary for Site 02320250

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
Ocala Limestone
LOCATION - Lat 30°00'21", long 82°59'51" referenced to North American Datum of 1927, in sec.34, T.5 S., R.13 E., Lafayette County, FL, Hydrologic Unit 03110205, on the southeast side of the spring pool in Troy Spring State Park, 200 feet upstream of the Suwannee River, 5.3 mi northwest of Branford, and 6.8 mi upstream from bridge on U.S. Highway 27.
DRAINAGE AREA - Indeterminate.
REVISIONS HISTORY - Total Dissolved Solid data published from July 2, 2014 to November 8, 2017 were removed from publication on April 2, 2018. 
PERIOD OF RECORD - 1942-1995 (9 miscellaneous discharge measurements), 1998, March 2002 to August 2005 (fragmentary), September 2005 to July 14, 2010, March 2014 to April 2014 (gage heights only), July 2014 to current year.
GAGE - Water-stage recorder, water-quality monitor, and data-collection platform. Datum of gage is not determined.
REMARKS - Discharges for the spring are not calculated during higher flows on the Suwannee River which overtop the spring.
SPECIFIC CONDUCTANCE:  July 2014 to current year.
WATER TEMPERATURE: July 2014 to current year.
DISSOLVED OXYGEN:  July 2014 to current year.
pH:  July 2014 to current year.
NITRATE:  July 2014 to current year.

Water-quality monitor consisting of temperature, specific conductivity, dissolved oxygen and pH.

Water-quality monitor measuring nitrate.


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. July 2014 to current year, water temperature, specific conductance and dissolved oxygen published as instantaneous maximum and minimum and daily mean; pH published as instantaneous maximum and minimum and daily median.


From August 21, 2021 to current the water-quality sensor is located several feet higher in the water column than from July 2, 2014 to August 21, 2021.  



Maximum instantaneous value: 419 µS/cm; several days in 2014.

Minimum instantaneous value: 10.5°C; Jan. 14, 2021.


Maximum instantaneous value: 9.1 mg/L; Jan. 14, 2021.

Minimum instantaneous value: 0.0 mg/L; May 29- June 4, 2016 and Sept. 16-23, 2021.


Maximum instantaneous value: 8.2 std. units; June 02, 2020

Minimum instantaneous value: 5.5 std. units; Dec. 23-27, 2018


Maximum instantaneous value: 3.04 mg/L; September 11, 2014
