The Department of Environmental Protection says Rocky Neck State Park in Niantic, Sherwood Island State Park in Westport and Silver Sands State Park in Milford are closed to swimming.

Hammonasset State Park in Madison is the only state park on the shoreline that remains open to swimming.

Four inland parks are also closed to swimming — Black Rock State Park in Watertown, Kettletown State Park in Southbury, Wadsworth Falls State Park in Middlefield, Wharton Brook State Park in Wallingford.

The swimming areas will reopen when tests show bacteria are at acceptable levels.
