A local swim area is closed because of elevated bacteria levels in the water. Kettletown State Park in Southbury is not granting access to the designated swim area because of that. The state Department of Energy and Environmental Protection tests the water weekly at state parks. DEEP says the elevated bacteria level could be from stormwater run off from the recent rainfall. The water will be retested and when the all clear is given, the beach area will be reopened. Local health departments are responsible for sampling municipal beaches and swimming areas.
