Lake Sarah (Murray County) Zebra Mussel Concern for Lyon County

AIS - Aquatic Invasive SpeciesLake Sarah in Murray County (MN) has what officials are describing as a 3-5 year old infestation of Zebra Mussels. Some believe they may have arrived on a dock that was purchased from an owner living on a lake infested with zebra mussels. Although this is speculation, this situation validates the need to Clean, Drain, & Dry ALL Boats, Docks, and Water Recreation Items.

Zebra Mussels were transported through ballasts of cargo ships through the great Lakes region, which then resulted in the transport from great lakes to nearby lakes and streams. As we see today they are still being transported by way of boats and other watercraft, docks, and waterfowl hunting equipment. These are all possible ways of transport and do not suggest that any one category is responsible.
