Click to hide Water-Year 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.

USGS Water-Year Summary 2023
262735081044601 HE 860.
Surficial aquifer system
Nonartesian Sand Aquifer
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.33 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 16 ft. Upper casing diameter 4 in; top of first opening 9 ft, bottom of last opening 14 ft.
DATUM - Land-surface datum is 26.9 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 - Electronic data logger.
REMARKS - Figures of water level as elevation, in feet NGVD, published for the period September 1977 to September 1987 are in error. A correction of +1.63 ft is required to correct this water-level data. Correction is based on an elevation survey completed on September 7, 1988. The station datum used for the period September 1977 to September 1987 was also incompletely described in Water Resources Data Reports, for the 1993 to 1995 water years. This error would suggest that the measuring point elevation used from September 1977 to September 1987 was 28.03 ft, rather than the measuring point elevation of 27.70 ft which had been used. 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.
EXTREMES FOR PERIOD OF RECORD - Highest water level, 27.23 ft above NGVD29, Sept. 10, 2017; lowest, 20.78 ft above NGVD29, May 17, 18, 2009.
