"In 2008, zebra mussels were first reported in Maryland within the Conowingo Pool of the Susquehanna River. The following year, biologists with the Department of Natural Resources found 11 adult zebra mussels downstream of Conowingo Dam while surveying fish and native mussel communities. Since 2009, there have been regular findings of zebra mussels in the Susquehanna River immediately downstream of the dam. More recently, DNR has observed zebra mussels attached to the anchors of the navigational and hazard buoys that are placed throughout the the Upper Chesapeake Bay annually. In 2014, a near fifty fold increase in the number of mussels attached and anchors colonized was found. Several municipalities in the area have also began reporting clusters of zebra mussels attached to their water supply intakes or larva entering their intake pipes." (Maryland DNR) (Read more)
