An old dam is bringing new life to the Chesapeake Bay. The Simkins Dam was removed from the Patapsco River, crushed into pieces and then scattered onto the floor of the bay to create an artificial reef. Stephanie Westby of the National Oceanic and Atmospheric Administration says the oysters will help filter the water and provide habitats for other species. The Chesapeake Bay Foundation will use a specially designed boat to scatter the oysters across the two-acre reef rising about a foot off the ocean floor. Westby says the Chesapeake Bay was once a highly productive oystering ground.
