While it may seem unusual for a shark to turn up in this part of Louisiana, Lake Pontchartrain isn't strictly a lake â it's an estuary, a coastal body of brackish water connected by rivers or streams to the open ocean. Bull sharks can survive in both saltwater and freshwater, and have been known to frequent the lake. But shark attacks are extremely rare, said John Carlson, a research biologist at the National Oceanic and Atmospheric Administration's Fisheries Service in Panama City, Florida.
