Minnesota Department of Natural Resources (DNR) biologists fear they might be seeing a disturbing trend of zebra mussels hitchhiking on boat lifts that are moved from infested waters to uninfested lakes.


The second such case was discovered this week on the northeast corner of Lake Irene in Douglas County, where a localized population of zebra mussels was discovered on a lift last weekend.

A similar case was discovered at Rose Lake in Otter Tail County September 28.
