USGS Water-Year Summary 2019
02320250 TROY SPRING NEAR BRANFORD, FL
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.  The rating computation has not yet been approved by USGS.
SURFACE-WATER RECORDS
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.
WATER-QUALITY RECORDS
PERIOD OF RECORD -
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.
INSTRUMENTATION -

YSI EXO2 water-quality monitor consisting of temperature, specific conductivity, dissolved oxygen and pH.

Satlantic SUNA V2 water-quality monitor measuring nitrate.

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. 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.
