Zebra mussels found in Sassafras River

The Maryland Department of Natural Resources recently confirmed the presence of zebra mussels in the lower Sassafras River, a tidal Eastern Shore tributary near the Susquehanna River, where the invasive species was first discovered in Maryland in 2008.

DNR biologists believe that the unusually low levels of salt in Upper Chesapeake Bay waters this summer may have played a role in allowing zebra mussels to expand their distribution to the Sassafras.

Boaters, anglers and other recreational water users who enjoy the lower Susquehanna River can help stop the spread of harmful zebra mussels to other Maryland waters by taking several simple steps.

Those include removing aquatic plants and mud from boats and trailers after their use; draining water from boat motors, bilges and live wells before departing; disposing of unused live bait on shore or in the trash, allowing equipment to dry at least two days between outings; and limiting boating between places where zebra mussels are known to be present - the Susquehanna and the Sassafras - and other water bodies in the state.
