CLA Removes New Fairfield Dock That Played Host To Invasive Zebra Mussels

NEW FAIRFIELD, CT—The shoreline of Candlewood Lake in New Fairfield is one dock less after the Candlewood Lake Authority (CLA) removed it due to a harmful invader—zebra mussels.

These pesky creatures may look cool, but they can damage ecosystems by harming native species, according to Professor Pierce of the University of Wisconsin who stated, “In order for a zebra mussel to live, it must attach itself to a hard object. Not only do zebra mussels attach themselves to things like rocks, logs, and the hulls of ships, they also attach themselves to native species. Many native mollusk species are at risk of becoming extinct or endangered because of zebra mussels.” In addition, they can lower water quality and clarity.

The dock that was removed on Thursday, November 12 by the CLA, had about 6-12 live zebra mussels attached to it and were solitary mussels that were not yet forming colonies.

“This is the first time in over 8 years that this dock has been removed from the lake so we are unsure how long these mussels have been in the water, and when they attached to the dock,” a representative from the CLA said.

No other zebra mussels were found on neighboring docks and the CLA will continue to monitor the situation by combing the shoreline during the deep drawdown this winter.

The CLA is asking the public to clean, drain and dry their boats, kayaks and other nautical equipment before dropping them into the lake to help stop any potential invaders.
