Alasmidonta varicosa had not been previously documented by MANTA surveys (Figure 5). In 2009, we collected five dead specimens of varied condition from two sites in the Upper Potomac River (Table 1). It was not possible to investigate environmental conditions coincident with A. varicosa because of the lack of collection records. Figure 5. Locations where A. varicosa (brook floater) was collected. 16
Anodonta implicata Say 1829 was encountered at three sites in 2009 (Table 1). They were found to be common on a gravel shoal in the Susquehanna River upstream of Port Deposit. Previously, A. implicata was collected 8 times in four 8-digit watersheds (Figure 6). An earlier record from Flat Run in the Upper Monocacy watershed was determined to be a misidentification. Anodonta implicata has been collected within or in the vicinity of tidally influenced water. Due to a lack of collection records with associated data we were unable to investigate environmental conditions found at sites with A. implicata. Figure 6. Locations where A. implicata (alewife floater) was collected. 17
