        SW 1/4 sec.33, T.36 S., R.25 E., DeSoto County, Hydrologic Unit 03100101, 235 ft east 
        of U. S. Highway 17,    and 3.8 mi south of Gardner. 

AQUIFER.--Avon Park formation of Eocene Age, Geologic Unit 124AVPK. 

WELL CHARACTERISTICS.--Drilled, observation well, diameter 12 in., depth 1,320 ft, cased 
        to 580 ft. 

INSTRUMENTATION.--Water-stage recorder--60-minute interval. 

DATUM.--Land-surface datum is 75.37 ft above National Geodetic Vertical Datum of 1929.
  Measuring point: Top of recorder shelter floor, 2.49 ft above land-surface datum.
  Land surface datum is 74.33 ft above North American Vertical Datum of 1988. Water level elevations computed
  using NGVD 29 in order to maintain consistency with historical records.
   
PERIOD OF RECORD.--March 1978 to September 2010; October 2010 to current year (miscellaneous water level measurements).

REVISED RECORDS.--The maximum water level elevations for April 21, 2004 to September 30, 2005 were published in error.
  These data have been corrected in the files of the U.S. Geological Survey. WDR-US-2007:Land-surface datum.

CORRECTIONS.--The figures of water level as elevation, in feet NGVD, prior to Oct. 1, 1980, are in error.
  Correct elevations for data published prior to this date may be obtained by using datum correction of -2.03 ft.
  Revised records are in files of the Geological Survey.
