Three of five popular state swimming areas that were closed Wednesday over water quality concerns remain closed, but two have reopened on Thursday, according to the state Department of Energy and Environmental Protection.
The swimming areas at Chatfield Hollow and Wharton Brook have reopened.
The swimming areas at Day Pond State Park, Lake Waramaug State Park and Gay City State Park remain closed.
DEEP said the parks are being retested today and results will be available tomorrow.
The closures come as parts of the state are facing a heat advisory due to high temperatures and humidity.
The swim area at Mashamoquet Brook State Park is closed for the 2021 season for ongoing maintenance.
