Invasive snails spreading in Wisconsin waterways

Posted:
MADISON, Wis. (AP) -- State natural resources officials say some invasive snails with parasites deadly to waterfowl are continuing to spread in Wisconsin waterways.
   The Department of Natural Resources says the faucet snails have now been discovered in a small stream in Langlade County. The snails were found in Elton Creek near the Chequamegon-Nicolet National Forest.
   The National Wildlife Health Center says about 120,000 birds have died since 2002 in the Upper Mississippi region because of the parasites the snails carry. The creek is the first cold water stream in Wisconsin in which the snails have been identified.
   The Journal Sentinel reports the snails first arrived in the Great Lakes in the 1870s and have spread mainly in larger rivers in Wisconsin, including the Mississippi and Wolf.
