 The Minnesota DNR has confirmed zebra mussels in two more lakes in Crowin County. The newest detections are in Lower Cullen Lake and nearby Lake Hubert. A resort owner contacted the DNR after finding several zebra mussels on a boat moored at a resort on Lower Cullen Lake. DNR invasive species staff found no other zebra mussels during inspections of adjacent docks and a nearby stream. A county watercraft inspector and a lake service provider business both trained by the DNR spotted adult zebra mussels on a boat lift as it was removed from Lake Hubert. DNR invasive species staff found and removed more zebra mussels on an adjacent dock and at a three-foot depth in the water. Now zebra mussels are an invasive species that can compete with native species for food and habitat, cut the feet of swimmers, reduce the performance of boat motors, and cause expensive damage to water intake pipes. Zebra mussels have now been detected in at least 50 bodies of water in Crowin County.
