USGS STATION NUMBER.-- USGS 255208080274001
LOCATION.-- Lat 25°52'12.0", long 80°27'23.3" referenced to North American Datum of 1983, in NE 1/4 NW 1/4 sec.5, T.53 S., R.39 E., Miami-Dade County, FL, Hydrologic Unit 03090202, 1.0 mi southwest of junction of Pennsuco Canal and Dade/Broward Levee, 5.5 mi southwest of Pennsuco, and 7.5 mi north of U.S. Highway 41.
AQUIFER.-- Biscayne limestone aquifer of the Pleistocene Age, Geologic Unit 112 BSCNN.
WELL CHARACTERISTICS.-- Depth 15 ft. Upper casing diameter 6 in.; top of first opening 10 ft, bottom of last opening 15 ft.
DATUM.-- Top of base, 14.38 ft above National Geodetic Vertical Datum of 1929, May 1, 2002, to present
PERIOD OF RECORD.-- July 1958 to current year.
REMARKS.-- Station reconstructed on May 1, 2002 to stabilize the well. Data for the period December 13, 2001 to May 1, 2002, has been corrected to the extent possible but should be considered poor. See DATUM.
EXTREMES FOR PERIOD OF RECORD.-- Highest daily maximum water level, 8.78 ft NGVD, Oct. 14, 1960; lowest, 2.07 ft NGVD, June 2, 1962.

The change in daily water-level elevations correlates with time to a 95-percent degree of confidence for the past 35 years of record. A linear regression has been performed against the daily maximum water-level elevations for the past 35 years to quantify a long-term trend in the data. The estimated long-term trend in water level is 0.006 ft/year. (Description of statistical methods)
