On Sunday, July 11, the Trustees of Reservations had a possible shark sighting off of Norton Point. Lifeguard Lizzie Williamson told The Times that the South Beach lifeguards closed the water at 1:30 pm in an attempt to confirm the sighting. Both the on-land guards and biplanes from Katama Airfield were unable to confirm the presence of a shark, so the beach was reopened at 3 pm.
Brian Usher, a member of the park patrol, told the Times that sometimes beach-goers mistake animals such as seals or sunfish as sharks.
The lifeguards will continue to closely monitor the water for potential danger to swimmers.
