Water-level conditions in southern Florida
All data presented on this site are considered to be PROVISIONAL DATA and subject to revision pending further review.
USGS STATION NUMBER.-- USGS 262158081283403
LOCATION.-- Lat 26°22'00", long 81°28'36" referenced to North American Datum of 1927, in SE 1/4 SW 1/4 sec.24, T.47 S., R.28 E., Collier County, FL, Hydrologic Unit 03090204, 30 ft north of County Road 846, 2.8 mi east of Oil Grade Road and 4.5 mi southwest of Immokalee.
AQUIFER.-- Lower Tamiami aquifer of the Pliocene Age, Geologic Unit 121 TMIM.
WELL CHARACTERISTICS.-- Depth 160 ft. Upper casing diameter 6 in.; top of first opening 150 ft, bottom of last opening 160 ft. Artesian well, open hole 150 to 160 ft.
DATUM.-- Top of flange, 25.41 ft above National Geodetic Vertical Datum of 1929, Sep. 18, 2002, to present
PERIOD OF RECORD.-- October 1984 to August 2002 (monthly), September 2002 to current year.
REMARKS.-- The figures of water levels as elevation, in feet NGVD, prior to October 1, 2001, are in error. A +6.07 ft correction has been applied to correct water-level data prior to October 2001. Corrected records are in the files of the U.S. Geological Survey. Extremes for period of record have been adjusted to present datum. See DATUM.
EXTREMES FOR PERIOD OF RECORD.-- Highest water level measured, 21.27 ft NGVD, July 24, 1991; lowest, 0.84 ft below NGVD, Mar. 31, 1989.

The change in daily water-level elevations has not been mathematically correlated to time for the period of record based on operational considerations. Instead of a long-term trend line, the data are, therefore, compared to the zero-slope (flat, linear) regression curve for the existing period of record daily water-level elevations. This approximates, but may not equal, the period of record mean. (Description of statistical methods)
