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 261735080534002
LOCATION.-- Lat 26°18'09", long 80°53'35" referenced to North American Datum of 1927, in NW 1/4 NE 1/4 NW 1/4 sec.24, T.48 S., R.34 E., Hendry County, FL, Hydrologic Unit 03090202, 35 ft south of County Road 833, 0.75 mi west of the Broward County line and 5.2 mi east of the Big Cypress Forest Office.
AQUIFER.-- Surficial aquifer of the Pleistocene Age, Geologic Unit 112 NRSD.
WELL CHARACTERISTICS.-- Drilled, observation, water-table well, diameter 4 in., depth 11 ft, cased to 7 ft, 3 ft of screen.
DATUM.-- Top of shelf, 17.13 ft above National Geodetic Vertical Datum of 1929, Sep. 1, 1977, to present
PERIOD OF RECORD.-- September 1977 to November 1977 (monthly), December 1977 to September 1983 (daily), October 1983 to September 1988 (monthly), October 1988 to current year.
REMARKS.-- The figures of water levels as elevation, in feet NGVD, published prior to September 1990 are in error. See DATUM. The well went dry in April 2003 because of construction-related dewatering in the immediate area.
EXTREMES FOR PERIOD OF RECORD.-- Highest daily maximum water level, 14.62 ft NGVD, Aug. 23, 1978; lowest, 5.89 ft NGVD, Apr. 7, 2003. Well was dry during the period of Apr. 8 to May 10, 2003. See REMARKS.

The change in daily water-level elevations correlates with time to a 95-percent degree of confidence for the past 35 years. A third-order regression has been performed against the daily water-level elevations for the past 35 years to quantify a long-term trend in the data. The estimated first-order long-term trend in water level, using the Seasonal Kendall Slope Estimator, is 0.0030 ft/year, measured over the last 25 years (12-JAN-2012).
