USGS Water-Year Summary 2018
02319302 MADISON BLUE SPRING NEAR BLUE SPRINGS, FL
LOCATION - Lat 30°28'49", long 83°14'40" referenced to North American Datum of 1927, in SW 1/4 sec.17, T.1 N., R.11 E., Madison County, FL, Hydrologic Unit 03110203, 40 ft downstream from the spring pool, near right bank, 20 ft upstream of the Withlacoochee River and 10.2 mi east of Madison.
DRAINAGE AREA - Indeterminate.
REVISIONS HISTORY - Total Dissolved Solid data published from July 7, 2014 to November 7, 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 - 1932, 1946, 1956, 1961, 1963, 1974, 1977, 1985, 1990-91, 1993, 1995-96, 1998 (miscellaneous discharge measurements), February 2002 to current year. Prior to February 2002, published as Blue Spring near Madison.
GAGE - Water-stage recorder, acoustic velocity meter, and data-collection platform. Datum of gage is 33 ft above NGVD of 1929 and 32.28 ft above NAVD of 1988. Prior to February 2002, non-recording gage at same site at NGVD of 1929.
COOPERATION - This gage is monitored in cooperation with the Suwannee River Water Management District.
REMARKS - At stages below 9.00 ft discharge computed from elevation at Blue Springs well near Madison, FL (302847083145401). At stages above 9.00 ft a differential head rating is used, using Blue Springs well near Madison, FL (302847083145401) and the stage at the site. During periods of high water, the spring is affected by variable backwater from the Withlacoochee River, which at times, can result in negative flow back into the spring vent. Prior to Oct. 7, 2011, discharge was computed using different methods.
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 - Water-quality monitor and data-collection platform.
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 September 2014, 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.
