Oyster lovers and residents near Virginia Beach, Virginia remember a time that oysters from the Lynnhaven Bay watershed were once a celebrated delicacy served to dignitaries. Excessive bacteria levels in the Lynnhaven Bay watershed, however, forced the Virginia Health Department to shut down almost all of the shellfish areas for decades-until recently. Implementing the Lynnhaven Bay, Broad Bay, and Linkhorn Bay fecal coliform TMDL for shellfish areas has helped to reduce bacteria levels. Management actions targeting sources such as boating activities, on-site sewer systems, agricultural areas, and pet waste have successfully reduced bacteria levels. As a result of these efforts, Lynnhaven Bay watershed shellfish areas are reopening and Lynnhaven oysters are returning as an edible, marketable natural resource on local restaurant menus.
