INVASIVE FAUCET SNAIL EXPANDS RANGE TO NORTHERN WISCONSIN STREAM

July 7, 2015

MADISON -- Invasive faucet snails have been discovered in Elton Creek in Langlade County and stream users are being encouraged to remain vigilant against the invaders.

While the small snails can out-compete native snails, the greatest concern stems from their role as a host for parasites known to kill waterfowl that eat infected snails. The Wisconsin Department of Natural Resources is now working to identify the snails' distribution in the area.

Previously found in the Great Lakes, the Mississippi River and the Wolf River system, this is the first known occurrence of the snail in a small, cold water stream in the region. While the faucet snail was likely introduced into the Great Lakes through ship ballast, its spread may be occurring by transport on watercraft, recreational gear and even waterfowl.

Bob Wakeman, DNR aquatic invasive species coordinator, said the finding serves as a reminder to check boats and gear before leaving a waterway.

"Everyone needs to inspect their gear for plants, animals, mud and debris, remove anything that they find and drain all the water from their craft," Wakeman said. "These actions are required by law when you're fishing from a boat, trout fishing, trapping or even hunting waterfowl."

Wakeman said aquatic invasive species monitoring by DNR and partner groups around the state plays an important role.

"Better knowledge of where invasive species are located combined with existing and new outreach efforts will help us stop the spread of invasive species," he said. "It is up to each water user to protect Wisconsin's waters."

For more information, search the DNR website, dnr.wi.gov, for "aquatic invasive species efforts." A list of regulated aquatic invasive species including faucet snails (exit DNR) can be found on the DNR website by searching for "regulated invasive aquatic invertebrates."
