Site information from 2007 Data Report:

USGS STATION NUMBER.-- USGS 264101081443001

LOCATION.-- Lat 26°41'00", long 81°44'27" referenced to North American Datum of 1927, in NW 1/4 NW 1/4 sec.5, T.44 S., R.26 E., Lee County, FL, Hydrologic Unit 03090205, at J. Hudson House, 0.30 mi east of Orange River Loop Road, 0.50 mi north of Orange River Road, and 8.5 mi northeast of Fort Myers Post Office.

AQUIFER.-- Lower Hawthorn aquifer of Oligocene to Miocene Age, Geologic Unit 122 LMSN.

WELL CHARACTERISTICS.-- Depth 598 ft. Upper casing diameter 6 in.; top of first opening 188 ft, bottom of last opening 598 ft. Artesian well, open hole 188 to 598 ft.

DATUM.-- Top of 2-in. plug on pressure gage, 8.84 ft above National Geodetic Vertical Datum of 1929, April 1, 1967, to present

PERIOD OF RECORD.-- October 1967 to October 1969 (semiannual), February 1970 to August 1971 (quarterly), October 1971 to December 1974 (bimonthly), January 1975 to September 1993 (monthly), October 1993 to September 1994 (intermittent), October 1994 to August 2002 (monthly), September 2002 to current year.

REMARKS.-- Records of water levels prior to October 1975 are available in files of the U.S. Geological Survey. Records of water levels from May 1998 to September 27, 2002, are considered to be estimates because of problems identified with the pressure gage and precise measuring point used. Well was also used for salinity monitoring, May 1980 to April 1993.

EXTREMES FOR PERIOD OF RECORD.-- Highest water level measured, 48.6 ft NGVD, Oct. 24, 1995; lowest, 29.3 ft NGVD (estimated), Jan. 24 and Feb. 21, 2002. See REMARKS.

Current 30-day hydrograph at L - 652 (264101081443001)

Graph: 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 this graph is available via the [data used] link on the page.

Long-term trend information

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)
