Sand Shoal Channel, marked by lights and daybeacons, extends westward from Sand Shoal Inlet for 6 miles where it joins a marked dredged channel leading to the wharves and public bulkhead at Oyster on the mainland. In 2010, the midchannel controlling depth was 3 feet, thence 5 feet was in the basin at Oyster. Public piers and a launching ramp are on the northern side of the basin. Numerous wrecks are reported near these facilities; caution is advised.
