Despite some spotty problems the Candlewood Lake Authority says every test for a toxin sometimes released by blue-green algae on Thursday was far below the state threshold.  The Lake Authority has been receiving reports of small blue-green algae blooms in some coves around the lake, following days of rainfall and then nice days of sunshine, which creates the right conditions for blue-green algae growth.  The testing program at the Town Beaches on Candlewood Lake runs throughout the summer.
