Summary
instructions
and
information
- Water-Year Summary reports summarize a year of hydrologic data in a printer-friendly format.
- For water years 2014 onward, choose a water year and parameter and an on-demand Water-Year Summary report will be generated.
- For water years 2006 through 2013, choose a water year and an Annual Water Data Report will be provided.
- For water years 2005 and earlier, Annual Water Data Reports may be available in digital format.
- Not all sites have reports available for every water year.

Surficial aquifer system
Tamiami Formation
Tamiami Formation
LOCATION - Lat 26°27'37", long 81°04'36" referenced to North American Datum of 1927, in SE 1/4 SE 1/4 sec.24, T.46 S., R.32 E., Hendry County, FL, Hydrologic Unit 03090202, 20 ft north of County Road 833, 3 mi east of County Road 846, and 23 mi east of Immokalee.
GROUNDWATER RECORDS
WELL CHARACTERISTICS - Depth 59 ft. Upper casing diameter 4 in; top of first opening 58 ft, bottom of last opening 59 ft. Open hole 58 to 59 ft.
DATUM - Land-surface datum is 26.6 ft above National Geodetic Vertical Datum of 1929. Measuring point: Undefined. See REMARKS.
PERIOD OF RECORD - September 1977 to September 1979, November 1985 to September 1994 (monthly), October 1994 to September 1995 (quarterly), May 2003 to current year.
GAGE - In-Situ Level Troll 500 pressure transducer.
REMARKS - Station was surveyed during the 1988 water years and the land-surface datum and height of the measuring point were corrected. The figures of water levels as elevation, in feet NGVD, from September 1977 to September 1987 are in error. A correction of +1.30 ft is required to correct this water-level data. Well was also used for salinity monitoring from February 1978 to April 1993. Chloride and conductivity profiles, and records of water level prior to November 1985, are available in the files of the Geological Survey. See DATUM and PERIOD OF RECORD.
EXTREMES FOR PERIOD OF RECORD - Highest water level, 25.84 ft NGVD, Sept. 11, 2017; lowest, 8.53 ft NGVD, Dec. 14, 2010.
