REMARKS - Data from artesian wells measured with a calibrated pressure gage are considered accurate to +/-0.1 ft. 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. A 1.1 correction should be applied to data published from August 17. 2001 to September 30, 2010. Well monitored weekly for water quality from June 2007 to Aug. 2007, monthly from Sept. 2007 to July 2008. Well destroyed due to road widening project and replaced with C-948R (261342081352901) See DATUM.
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. See REMARKS.
