Abstract : The National Marine Fisheries Service (NMFS) and the Corps of Engineers have cooperatively developed and implemented regional demonstrations of beneficial uses of excavated material using two Baltimore District Federal maintenance dredging projects. At the Slaughter Creek, Dorchester County, Maryland, Federal project, the excavated material and the contractor-provided oyster shell clutch was used to rehabilitate an existing unproductive oyster bar. At the Twitch Cove, Smith Island, Somerset County, Maryland, Federal project, the excavated material and a wave-energy dissipating structure called a Longard tube were used to create a submersed aquatic eelgrass (Zostera sp.) bed in a moderately high-energy area. The Slaughter Creek and Twitch Cove projects were completed in July 1987. The submersed aquatic grass bed associated with the Twitch Cove project was transplanted in September 1987. The success of both projects will be monitored in fall 1987 and spring 1988.
