» The easy days of swimming with the manatees at Three Sisters Spring in Citrus County are ending under a proposal that was unveiled Wednesday by the U.S. Fish and Wildlife Service. The public has until Sept. 4 to comment on new regulations that are designed to protect the endangered marine mammals from human harassment or injury, the Tampa Bay Times reported. Three Sisters Springs is the only confined body of water in the U.S. open to the public while wintering manatees are present. The famous springs are connected to King's Bay, a waterway that Jacques Cousteau featured in an "Undersea World" special in 1973.
