Photograph of dense beds of wild celery (Vallisneria americana), eurasian watermilfoil (Myriophyllum spicatum), and hydrilla (Hydrilla verticillata) taken on 09/19/04 in the Elk River near Paddy Biddle Cove. This is one area that has dramatically expanded and contributed to the large increase in SAV in the Upper Bay Zone in 2004.
