WELL CHARACTERISTICS.-- Depth 420 ft. Upper casing diameter 6 in.; top of first opening 370 ft, bottom of last opening 420 ft. Artesian well, open hole 370 to 420 ft.

DATUM.-- Top of 4-in. plug, 15.20 ft above National Geodetic Vertical Datum of 1929, Aug. 17, 2001, to present

PERIOD OF RECORD.-- October 1984 to April 2001 (Monthly), May 2001 to current year. See REMARKS.

REMARKS.-- Records of water levels from Water Years 2003 through 2005 are considered to be in error. Corrected records are found in files of the U.S. Geological Survey. Unpublished records of water levels as elevation from Water Year 2006 are available in this publication. See 2006 Water Year table below.

EXTREMES FOR PERIOD OF RECORD.-- Highest water level measured, 37.6 ft NGVD, Nov. 25, 1987, Jan. 28, 1988 and Sept. 28, 1995; lowest daily maximum water level, 24.14 ft NGVD, Apr. 26, 2007.

Current 30-day hydrograph at C - 948 (261347081351701)

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)
