C - 687, USGS ID 262554081283801 [NWIS]

Site information from 2007 Data Report:

USGS STATION NUMBER.-- USGS 262554081283801

LOCATION.-- Lat 26°25'54", long 81°28'39" referenced to North American Datum of 1927, in NE 1/4 SW 1/4 sec.36, T.46 S., R.28 E., Collier County, FL, Hydrologic Unit 03090204, in island of Tippins Terrace Road, 0.1 mi south of County Road 890, 3.2 mi west of the Immokalee Post Office.

AQUIFER.-- Sandstone aquifer of the Miocene Age, Geologic Unit 122 SNDS.

WELL CHARACTERISTICS.-- Depth 310 ft. Upper casing diameter 4 in.; top of first opening 290 ft, bottom of last opening 310 ft. Artesian well, open hole 290 to 310 ft.

DATUM.-- Top of casing, 26.49 ft above National Geodetic Vertical Datum of 1929, July 12, 2005, to present

PERIOD OF RECORD.-- October 1981 to September 1982 (intermittent), October 1982 to July 2002 (monthly), August 2002 to current year.

REMARKS.-- Well was rebuilt and resurveyed July 12, 2005. The figures of water level as elevation, in feet NGVD, prior to October 1985 are in error. A correction of +15.43 ft has been applied to correct water-level data. Corrected records are in the files of the U.S. Geological Survey. See DATUM. Records of water levels prior to October 1983 are available in files of the U.S. Geological Survey.

EXTREMES FOR PERIOD OF RECORD.-- Highest water level measured, 25.38 ft NGVD, Aug. 31, 1995; lowest, 4.03 ft NGVD, Apr. 24, 1989.

Current 30-day hydrograph at C - 687 (262554081283801)

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)
