Rock Springs Run is an 8-mile river that forms the boundary between Wekiwa Springs State Park and Rock Springs Run State Reserve. Rock Springs Run eventually flows into the Wekiva River, which then runs 15 miles and empties into the St. Johns River. The Wekiva River Basin includes Wekiwa Springs Run, Rock Springs Run, the Wekiva River, Blackwater Creek and Seminole Creek. These waterways are the first congressionally designated National Wild and Scenic River basin in Florida. The Ethel Cemetery, located in Rock Springs Run State Reserve, is the oldest known cemetery in Lake County, built in 1880. The cemetery was located in the town of Ethel, which was a railway stop town formerly known as Moody. Citizen support organisation volunteers constructed a new entrance and fence for the cemetery, which contains four intact grave markers.
