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

WELL CHARACTERISTICS.-- Depth 390 ft. Upper casing diameter 4 in.; top of first opening 298 ft, bottom of last opening 390 ft. Artesian well, open hole 298 to 390 ft.

DATUM.-- Top of casing, 22.65 ft above National Geodetic Vertical Datum of 1929, Mar. 26, 2007, to present; Top of base, 22.74 ft above National Geodetic Vertical Datum of 1929, Dec. 1, 1986, to Mar. 26, 2007

PERIOD OF RECORD.-- April 1986 to September 1986 (semiannual), December 1986 to current year.

REMARKS.-- The figures of water levels as elevation, in feet NGVD, prior to October 2001, are in error. A +6.07 ft correction has been applied to correct water level data from October 1985 to September 2001. Corrected records are available in the files of the U.S. Geological Survey. See DATUM. Records of water levels prior to December 1986 are available in the files of the U.S. Geological Survey. Extremes for period of record have been adjusted to present datum. See DATUM.

EXTREMES FOR PERIOD OF RECORD.-- Highest daily maximum water level, 22.05 ft NGVD, Aug. 28-31, 1995; lowest, 0.77 ft below NGVD, Apr. 26, 1990.

Current 30-day hydrograph at C -1079 (262158081283404)

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 correlates with time to a 95-percent degree of confidence for the past 35 years of record. A linear regression has been performed against the daily maximum water-level elevations for the past 35 years to quantify a long-term trend in the data. The estimated long-term trend in water level is 0.018 ft/year. (Description of statistical methods)
