USGS Water-Year Summary 2019
02319800 SUWANNEE RIVER AT DOWLING PARK, FL
LOCATION - Lat 30°14'41", long 83°14'59" referenced to North American Datum of 1927, in NW 1/4 sec.08, T.3 S., R.11 E., Lafayette County, FL, Hydrologic Unit 03110205, at bridge on County Road 250 at Dowling Park and 112 mi upstream from mouth.
DRAINAGE AREA - 7,190 mi². includes part of watershed in Okefenokee Swamp, which is indeterminate.
REVISIONS HISTORY - Revisions: Daily values for temperature and specific conductance records for March 2, 2017, March 21-22, 2017, April 19, 2017, July 20-22, 2017, July 26, 2017, August 8-12, 2017, August 14, 2017, and August 30, 2017 were revised on March 9, 2018.   Daily values were computed with insufficient unit values and did not meet the USGS minimum criteria for publication. 

Revisions: Gage height and discharge for the period Apr. 11, 2014, to Oct. 17, 2017, were revised on May 22, 2018, based on an error discovered during routine levels ran on Feb. 15, 2018. Mean gage heights for discharge measurements 104-134, shift curves for measurements 122-134 , and the gage height peaks for water years 2015, 2016, and 2017 were revised.
SURFACE-WATER RECORDS
PERIOD OF RECORD - March 1950 to August 1954 and November 1975 to October 1977 (annual maximum discharge and gage-height), October 1996 to current year.
GAGE - Water-stage recorder and data-collection platform. Datum of gage is National Geodetic Vertical Datum of 1929.
EXTREMES OUTSIDE PERIOD OF RECORD - Flood of Apr. 7, 1948, reached a stage of 61.46 ft, from floodmarks; discharge, 92,600 ft³/s.
WATER-QUALITY RECORDS
PERIOD OF RECORD - Water-quality monitors installed March 2, 2017.  Period of record from March 2, 2017 to current year.
INSTRUMENTATION - YSI-600R water-quality monitor consisting of temperature and specific conductivity.
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.
