Savannah-Chatham police spokesman Julian Miller said investigators don’t know how the woman died or how long she’d been in the water.
Police are trying to identify the body, described as a white woman between 30 and 50 years old, with shoulder-length, dirty blond hair.
The body was found near Knoxbrook Creek by two fishermen about 5 p.m. The Coast Guard was called to the scene, and the body was taken to the Houlihan Boat Ramp.
The body was found near the spot where Chatham County, Effingham County and South Carolina meet. Savannah-Chatham police are investigating the case after it was determined to be in their jurisdiction.
Miller said investigators do not believe the body to be related to a Saturday report of stranded boaters in Effingham County. The Effingham County sheriff’s office, the Georgia Department of Natural Resources and the U.S. Coast Guard were called out on that report.
Effingham County sheriff’s spokesman David Ehsanipoor said three people aboard the boat were found safe. They’d had mechanical trouble.
