SOUTHBURY — Kettletown State Park’s swimming area has been closed due to high blue green algae levels.
Water quality tests performed Friday by the state Department of Energy and Environmental Protection found elevated levels of blue green algae, which can create toxic blooms, in the park’s swimming area. All other state swimming areas remain open, except Wharton Brook in Wallingford, which has been closed for storm damage.
Kettletown has struggled with blue green algae in recent years, including a period last summer when high levels of the algae closed the swimming area for several weeks, one of the longest closures at a state park for the cyanobacteria. The park was also closed for 21 days because of the blue green algae in 2015.
