In response to a global sea-level decline, the Florida Platform emerges from the sea. While the Florida Platform is exposed above sea-level, the slow but steady process of karstification by acidic rainfall forms the void spaces in the limestone, some of which would later become Florida’s springs. Fossil remains of the first land mammals that found their way into Florida during this time can be found in sinkhole deposits today.
The Wacissa Spring Group lies at the northern end of the Aucilla Wildlife Management Area in Jefferson
County and forms the headwaters of the Wacissa River. Over twenty springs form a cluster that runs
along the river. A public boat ramp allows for easy access to the core of the spring cluster. This dense
core contains Log, Thomas, Wacissa #1-4, and Acuilla springs, which together form a large bowl of fast-
flowing water. Along the run, large patches of Coontail compete with beds of Hydrilla beneath the clear
water. The combined magnitude and isolation of the Wacissa springs make the location one of the most
pristine in the state, earning the system a spot on the list of OFSs despite none of the individual springs
flowing at the first magnitude.
