2017/2018 Well Comparisons in Alachua County

During the past two months, rainfall has been below normal in central Alachua County, but Floridan Aquifer levels remain above the 95th percentile in many parts of the county. The graph included shows how levels in two Floridan Aquifer wells in Alachua County have varied since January 2017.

Higher than normal rainfall in the summer of 2017 had an especially large effect at the well on the University of Florida (UF) campus (red line), with a rise of more than 7 feet even before Hurricane Irma. In the month that followed Irma, water level in the UF well rose another 3 feet. Water level remained high at the UF well through this summer and is still near the maximum that occurred in mid September.

The USGS well south of Newberry in western Alachua County (blue line) rose less in the summer of 2017 before Hurricane Irma, which is probably because of lower rainfall in that area compared to Gainesville in the months before Irma. The water level at this well reached its record maximum in mid-October 2018.
