A look at reef building
Granite rock, which is brought in by barge, is methodically placed in the Piankatank River near Gwynn’s Island in Mathews County Virginia. The rock is the basis for the newest, 25-acre oyster reef in the Chesapeake Bay Watershed. The Norfolk District, U.S. Army Corps of Engineers, is overseeing the more than $2 million sanctuary reef project in partnership with the Virginia Marine Resources Commission and the Nature Conservancy.
