The U.S. Army Corps of Engineers sidecast dredge Merritt did maintenance dredging at Lockwoods Folly Inlet in North Carolina. The project was completed on September 3.
The Lockwoods Folly Inlet Project was authorized as a federal navigation project in 1890. The authorized dimensions are 8 feet deep and 150 feet wide. The inlet was last dredged in May 2016 using non-federal funds. The project has not been included in a president’s budget since 2005, and last received federal funding in 2013 through Hurricane Sandy emergency supplemental funds. The Wilmington District said there are no federal funds available for maintenance dredging activities in the area, and the work of the dredge Merritt is done outside of the federally authorized projects.
