Edwards Spring, Suwannee River 2025-04-22

After Hillman Bridge, WUFT News Reporter Andrew Sheridan and I went to Edwards Spring.

Also known as Ellaville Spring, this is a second magnitude spring next to the Suwannee River, on private property.

It is just downstream from Suwannee River State Park, but you can’t get through from there anymore. Best to get permission from the landowner, as we did, before going there.

As TJ Johnson attested, he and other cave divers have established Edwards Spring connects under the Suwannee River to Suwannacoochee Spring on the other side of the Suwannee River, next to the Withlacoochee River.

In 2014, the Florida Geological Survey and the Suwannee River Water Management District (SRWMD) put dye into Falmouth Spring, inland from here, and the dye came out at both Ellaville Spring and Suwanacoochee Spring. SO there are connections al the way through the Falmouth Cathedral Cave System between those three springs. Continue reading →
