The state on Friday announced changes to the swimming restrictions at two state parks, which were put in place following the state’s first deadly shark attack.

Maine’s Bureau of Parks and Lands says water access at Popham Beach and Reid State Park is now limited to waist-deep water only.

Swimming at the beaches had been restricted to ankle-deep and knee-deep water.

The restrictions follow Monday’s deadly shark attack off Bailey Island. A 63-year-old New York City woman was fatally attacked by a great white shark while she was swimming with her daughter.

Officials also say swimming at Ferry Beach and Crescent Beach remains limited to waist-deep water only.

State park rangers and lifeguards will be on the lookout for possible shark activity, and they’ll clear the water if any concerns arise.
