FirstLight worked this summer with a team of zebra mussel ecologists to conduct a dive searching for the invasive species specimen below the level of the drawdown where they could continue to survive over the winter. During that dive, they found a total of 370 adult zebra mussels across over 30 dive sites.  The Candlewood Lake Authority's environmental DNA chemical analysis, in partnership with WestConn, showed two samples with low concentrations of Zebra Mussel DNA in the water.  CLA says that could be an indication of reproduction in the lake and adult mussel growth and survival.
