GROUNDWATER RECORDS
WELL CHARACTERISTICS - Depth 12.5 ft. Upper casing diameter 5 in; top of first opening 12.5 ft, bottom of last opening 12.5 ft.
DATUM - Land-surface datum is 6.82 ft above National Geodetic Vertical Datum of 1929. Measuring point: Top of base, 7.89 ft above National Geodetic Vertical Datum of 1929, Oct. 1, 1986 to Apr. 10, 2002; Top of base, 9.63 ft above National Geodetic Vertical Datum of 1929, Apr. 9, 2002 to Jul. 14, 2021; Black mark on top of flange, 9.55 ft above National Geodetic Vertical Datum of 1929, Jul. 14, 2021 to present.
PERIOD OF RECORD - October 1986 to current year.
GAGE - Satellite data collection platform.
COOPERATION - Miami-Dade County, U.S. Army Corps of Engineers, Everglades National Park.
REMARKS - During a major storm that occurred on October 3-4, 2000, heavy rains caused flooding that caused the float to come out of the well. The extreme water level shown for the period of record, on October 5, 2000, was determined by a manual depth to water measurement made from the measuring point. The actual highest water level that occurred could not be determined. On April 9, 2002, the shelter was rebuilt to prevent water from rising over the base in case of an extreme rain event. The figures of water level as elevation, in feet NGVD, between the period April 1, 1988 to September 30, 1995 are in error. Corrected records are in files of the U.S. Geological Survey.
EXTREMES FOR PERIOD OF RECORD - Highest water level, 8.82 ft NGVD, Nov. 12, 2020; lowest recorded, 1.25 ft NGVD, June 12, 2011.
