REMARKS - This well was also used for salinity monitoring until October 1998. Salinity monitoring was carried out by Florida Keys Aqueduct Authority from October 1998 to June 2004. The figures of water level as elevation, in feet NGVD, prior to October 1, 2003 has been revised. Corrected records prior to October 1984 are in files of the U.S. Geological Survey. The estimated error in water-level elevations from 1985 to 2003 is -0.02 ft. Because this is less than the published accurate of record no corrections have been applied. See DATUM. Records of water levels prior to October 1973 are available in files of the U.S. Geological Survey.
EXTREMES FOR PERIOD OF RECORD - Highest water level, 3.88 ft NGVD, Sept. 9, 2017; lowest daily, 1.76 ft below NGVD, May 30, 1965.
