Over the past decade, sightings of the zebra mussel, have increased in the Chesapeake Bay watershed. Zebra mussels can out-compete native species for space, food and nutrients. They also clog water intakes and damage equipment by attaching to boat motors and hard surfaces. Zebra mussels spread by attaching to watercraft, aquatic plants, nets, fishing equipment, or through water currents as larvae. For this reason, public awareness, education and warning are crucial elements in the fight against zebra mussel invasion. This map lists zebra mussel sightings in the Chesapeake Bay Watershed through 2010.
