All data presented on this site are considered to be PROVISIONAL DATA and subject to revision pending further review.
USGS STATION NUMBER.-- USGS 255300080370001
LOCATION.-- Lat 25°54'40", long 80°35'32" referenced to North American Datum of 1927, in T.52 S., R.35 E., Miami-Dade County, FL, Hydrologic Unit 03090202, Two gages are located on the east and west sides of the Levee 67A, 11.3 mi northeast of access gate at the Tamiami Trail. No section could be determine from existing maps.
DRAINAGE AREA.-- Indeterminate.
PERIOD OF RECORD.-- EAST GAGE: July 1991 to current year.
REMARKS.-- Rainfall data is available in files of the U.S. Geological Survey. The rainfall record was discontinued September 30, 2003. The U. S. Army Corps of Engineers maintains raingage after September 30, 2003.
EXTREMES FOR PERIOD OF RECORD.-- EXTREME STAGES FOR EAST GAGE FOR PERIOD OF RECORD: Maximum gage height, 10.48 ft Oct. 15, 1999; minimum, 7.22 ft May 22-23, 2001.

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.

Description of information presented in the current 30-day hydrograph at SITE 69 (255300080370001)
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)

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.

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.
