Did first dive this year in Piscataqua River Portsmouth this AM. One dive by Prescott Park under memorial bridge and other Pierce Island to dive the wall there. I always find neat artifacts in river. I was amazed that I saw what I think were Zebra mussels! The kind you see diving St. Lawrence seaway. I know they were not there last year when dove river. Am I halucinating and mistaking for something else? I hope I'm wrong. There were zillions of tiny little mussels. Had no camera so not able to take pics. This can't be a good thing. Any resident oceanographers, Marine Biologists to confirm?
