Bob Keistler, project manager of the Masonboro Inlet South Jetty Repair Project, inspects an area where large rocks have been placed by contractors to reinforce the jetty. The eastern most part of the jetty has actually sunk into the ocean floor because of currents and constant pounding by waves. The new layer of rocks will increase its effectiveness and help to stabilize it. Originally built in 1980, the south jetty helps ensure safe passage for private, commercial and Coast Guard boats and vessels by reducing the amount of sand on the ocean floor carried by currents into the inlet.
