Charleston Harbor has been a key economic driver for more than 300 years. With the deepest water in the region today, Charleston offers a maintained harbor of -45 feet (13.7 meters) of depth at mean low tide throughout the main shipping channel and -47 feet (14.3 m) in the entrance channel.
A five to six foot tidal lift provides even deeper access for several hours during the day.
In addition to having deep water now, the Port of Charleston is advancing a next-generation harbor deepening project. The U.S. Army Corps of Engineers completed the project’s reconnaissance study in the summer of 2010 and determined that there is not only a federal interest in the further deepening of Charleston Harbor, but also that it was most likely the best value for scarce public dollars.
This video will show the different types of dredging operations that go on in Charleston Harbor. The video then goes into describing the different stages of the dredging cycle to ultimately answer the question, “Where does the mud go?”
