While the superstructure and two of the four main gun turrets were removed, the barbette of one of the turrets remains visible above the water. Since her sinking, oil still leaks from the hull, with more than 2.3 quarts (2.18 l) escaping into the harbor per day. In 2004, the US Navy and the National Park Service oversaw a comprehensive computerized mapping of the hull, being careful to honor its role as a war grave. The navy considered non-intrusive means of abating the continued leakage of oil to avoid the further environmental degradation of the harbor.
