The U.S. Army Corps of Engineers Jacksonville District has temporarily suspended swimming and other water activities at the W.P. Franklin South Recreation Area located near Fort Myers. The Corps was notified this afternoon by the Florida Department of Environmental Protection (DEP) that an algal bloom upstream of the beach had tested positive for microcystin, a substance produced by freshwater cyanobacteria. Tests of water in the immediate vicinity of the beach were negative. However, the Corps has decided to suspend water activities at the beach until further notice.
