The state Department of Energy and Environmental Protection has restarted its weekly water quality sampling at parks. The swim area at the Kettletown State Park in Southbury was closed once again due to hazardous blue-green algae. Swimming has not been allowed at the park for the last few years for this reason and once again the swim area will be closed through the end of the year. DEEP will continue evaluating the water quality at Kettletown. The campground is open.
