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 252036080324300
LOCATION.-- Lat 25°20'19", long 80°32'47" referenced to North American Datum of 1927, in sec.30, T.58 S., R.38 E., Miami-Dade County, FL, Hydrologic Unit 03090202, approximately 1.3 mi northwest of S-18-C and approximately 1.8 mi east of Aerojet Road.
DRAINAGE AREA.-- Indeterminate.
PERIOD OF RECORD.-- October 1985 to current year.
REMARKS.-- Land surface is approximately 2.4 ft above National Geodetic Vertical Datum of 1929. Gage is capable of recording water levels below land-surface datum. Unpublished data prior to 1993 water year are available in the files of the U.S. Geological Survey. Unit value data prior to 1993 water year were not available for review to determine instantaneous maximum and minimum gage height.
EXTREMES FOR PERIOD OF RECORD.-- Maximum mean daily gage height, 3.58 ft Oct. 16, 1999; minimum, indeterminate, well was dry during many years.

Continuously recorded gage heights for the past 30 days are compared to daily (mean) gage heights from last year, the FY2000 water level schedule for Lake Okeechobee, and daily levels for the 2001 drought year.

The change in daily gage height 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 gage height elevations. This approximates, but may not equal, the period of record mean. (Description of statistical methods)
D
Continuously recorded gage heights for the past 90 days are compared to daily (mean) gage heights 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.

Daily mean gage heights for the year are compared to gage heights 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.

Gage heights for the past year are compared to the duration information for the corresponding weeks of the year. The duration statistics are based on a zero-slope linear regression of the data from the past 25 years.
