A boat traveling through Wyoming from Oklahoma to Montana was found to have zebra mussels on it. Wyoming Game and Fish officials found viable mussels attached to the hull of the craft during an inspection at a check station. The aquatic invasive species (AIS) are a threat to Wyoming’s lake, pond and river habitats. Once established, it’s nearly impossible to eradicate an infestation of zebra or quagga mussels, which can cause clogged pipes, damage boats and make shorelines less enjoyable. The boat was purchased near Lake Oologah in Oklahoma, which is known to be infested with zebra mussels. The owner removed the craft from the water 24 hours before transporting it.
