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 272524080242801
LOCATION.-- Lat 27°25'25.8", long 80°24'27.1" referenced to North American Datum of 1983, in NE 1/4 NW 1/4 sec.23, T.35 S., R.39 E., St. Lucie County, FL, Hydrologic Unit 03090202, on Rock Road, 0.14 mi west of White Road, 0.53 mi west of Kings Highway, and 5.0 mi south of Fort Pierce.
AQUIFER.-- Surficial aquifer system, Geologic Unit 110 SAQS.
WELL CHARACTERISTICS.-- Depth 11.77 ft. Upper casing diameter 4 in.; top of first opening 11.77 ft, bottom of last opening 11.77 ft. Open-end well.
DATUM.-- Top of flange, 23.15 ft above National Geodetic Vertical Datum of 1929, Feb. 1, 2001, to present
PERIOD OF RECORD.-- August 1967(intermittent), January 1968 to April 1979 (daily), October 1979 to September 1995 (monthly), August 1997 to current year.
REMARKS.-- Records of water levels prior to October 1973 are available in files of the U.S. Geological Survey. The figures of water levels, as elevation in feet NGVD, prior to August 1990 are in error. A +0.41 ft correction is required to correct the water-level data. See DATUM.
EXTREMES FOR PERIOD OF RECORD.-- Highest daily maximum water level, 21.17 ft NGVD, Oct. 16, 1999; lowest water level measured, 13.94 ft NGVD (present datum), June 24, 1987.

Continuously recorded water levels for the past 30 days are compared to daily (maximum) water levels from last year, the minimum and maximum daily levels for the corresponding weeks of the year for the site period of record, and daily levels for the 2001 drought year.

Description of information presented in the current 30-day hydrograph at STL- 125 (272524080242801)
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)

Continuously recorded water levels for the past 90 days are compared to daily (maximum) water levels from last year, the minimum and maximum daily levels for the corresponding weeks of the year for the site period of record, and daily levels for the 2001 drought year.

Long-term water-level elevation trends are estimated by statistical analysis, then water-level elevations for the past year are compared to the duration information, compensated for long-term trends, for the corresponding weeks of the year.
