Quagga & Zebra Mussels in the United States

Where did they come from?

Zebra and Quagga mussels are native to Eurasia. Until the mid 1980s there were no zebra mussels in North America. Quickly that changed when they were inadvertently introduced into waters near the Great Lakes region. It is suspected that zebra mussels hitched a ride in ballast water tanks of commercial ships. Zebra Mussels (Dreissena polymorpha) were first discovered in the United States in Lake St. Clair near Detroit, Michigan in 1988. Since the ’80s, zebra mussels have spread, unchecked by natural predators, throughout much of the eastern United States They currently infest much of the Great Lakes basin, the St. Lawrence Seaway, and much of the Mississippi River drainage system. The have spread up the Arkansas River into eastern Oklahoma. Quagga mussels invaded North America later than zebra mussels and have been confirmed in fewer waters, including the Great Lakes, the St. Louis area and now in the Lower Colorado River and Southern California.
