The Minnesota DNR is carrying out a first-of-its kind, fast attack on the zebra mussels recently found in Rose Lake in between Frazee and Vergas.


The invasive species with a reputation for killing off fish populations and destroying beaches with their sharp shells were found in the lake on Sept. 28.

According to the DNR, the zebra mussels were likely brought in from a boatlift that was transported from an infested lake -- likely Lake Lizzie, they say.
