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 265633080203001
LOCATION.-- Lat 26°56'35.2", long 80°20'43.2" referenced to North American Datum of 1983, in NE 1/4 NW 1/4 NE 1/4 sec.4, T.41 S., R.40 E., Palm Beach County, FL, Hydrologic Unit 03090202, on south side of State Road 706, 3.45 mi west of State Road 711 and 0.4 mi east of State Road 710, 12 mi west of Jupiter.
AQUIFER.-- Surficial aquifer system, Geologic Unit 110 SAQS.
WELL CHARACTERISTICS.-- Depth 17 ft. Upper casing diameter 6 in.; top of first opening 17 ft, bottom of last opening 17 ft. Open-end well.
DATUM.-- Top of base, 27.36 ft above National Geodetic Vertical Datum of 1929, July 1, 2003, to present. From June 1977 to July 2003, top of base was 27.37 ft above NGVD. From January 1993 to September 2000, top of base was considered to be 27.43 ft above NGVD. From May 1977 to January 1993, top of base was considered to be 27.00 ft above NGVD. Prior to June 1977, measuring point was 27.11 ft above NGVD. See REMARKS.
PERIOD OF RECORD.-- October 1973 to May 1977 (daily), May 1983 to December 1987 (intermittent), May 1988 to November 1992 (semiannual), January 1993 to December 1993 (monthly), January 1994 to current year.
REMARKS.-- Figures of water levels as elevation, in feet NGVD, from May 1983 to September 2000 are in error. Corrected records for October 1994 to September 2000 are based on a revised measuring point value of 27.37 ft, and are in the files of the U.S. Geological Survey. See DATUM.
EXTREMES FOR PERIOD OF RECORD.-- Highest daily maximum water level, 25.86 ft NGVD, Oct. 17, 18, 1995; lowest, 21.24 ft NGVD, Apr. 11, 1975.

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 PB - 689 (265633080203001)
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)
