The beginning of the Pleistocene epoch otherwise known as the ice age. Massive continental glaciers advance and retreat causing sea-levels to fluctuate widely. Florida is undergoing further karstification and the Floridan Aquifer System repeatedly fills and drains with saltwater from the oceans and fresh water from rain. Many of our springs are formed during this time as sinkholes and as water levels in fluctuate, some begin to discharge water becoming springs.
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.
