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 270124080280202
LOCATION.-- Lat 27°01'24.6", long 80°28'01.7" referenced to North American Datum of 1983, in NE 1/4 NE 1/4 SE 1/4 sec.6, T.40 S., R.39 E., Martin County, FL, Hydrologic Unit 03090202, near intersection of SW Washington Avenue and SW Osceola Street, 0.1 mi northeast of State Road 710.
AQUIFER.-- Surficial aquifer system, Geologic Unit 110 SAQS.
WELL CHARACTERISTICS.-- Depth 80 ft. Upper casing diameter 4 in.; top of first opening 25 ft, bottom of last opening 80 ft. Gravel-packed 25 to 80 ft. See REMARKS. (Corrected)
DATUM.-- Top of base, 35.7 ft above National Geodetic Vertical Datum of 1929, May 4, 2001, to present
PERIOD OF RECORD.-- September 1974 to current year.
REMARKS.-- The well has been reported to be open to the aquifer from 25 to 80 ft, but obstructed at a depth of 23 ft. Further investigation revealed that the well was finished with a gravel-packed screen throughout the open interval and so the well cannot be sounded to its full depth.
EXTREMES FOR PERIOD OF RECORD.-- Highest daily maximum water level, 34.05 ft NGVD, Sept. 26, 2004; lowest, 24.65 ft NGVD, May 22, 2001.

D
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.
Data used to produce the current 30-day hydrograph at M -1048 (270124080280202)
Description of information presented in the current 30-day hydrograph at M -1048 (270124080280202)
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 -0.014 ft/year. (Description of statistical methods)
D
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.

The estimated long-term trend in water level is -0.014 ft/year. (Description of statistical methods)
D
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.
