LOCATION - Lat 30°21'40", long 83°08'07" referenced to North American Datum of 1927, in sec.32, T.1 S., R.12 E., Suwannee County, FL, Hydrologic Unit 03110205,

DRAINAGE AREA - Indeterminate

REVISIONS HISTORY -

Total Dissolved Solid data published from May 23, 2015 to February 14, 2018 were removed from publication on April 2, 2018.

Nitrate data was revised on January 16, 2020 after a level 2 audit to remove erroneous data during backwater conditions. Data was determined to be erroneous due to backwater and removed on June 16-18, 2018, June 20-23, 2018, December 18-22 2018, December 30 to January 21 2019 and February 9 to 15, 2019. Additional erroneous data points on August 19 and 24, 2016 were removed.
