254344081095101 MO - 216
Biscayne Limestone Aquifer
LOCATION - Lat 25°43'44.5", long 81°09'51.3" referenced to North American Datum of 1983, Monroe County, FL, Hydrologic Unit 03090204, located 7mi west of the 40-Mile Bend Check Station along Loop Road Big Cypress National Preserve, 11.5 mi south of Mitchell Landing campground, 11.7 mi northwest of Coconuts Camp.
REVISIONS HISTORY - Groundwater levels on Apr. 24, 2017, were revised on Feb. 12, 2018, due to the removal of a data spike.  The daily maximum elevation, NAVD 88, on Apr. 24, 2017 was revised.
