The data on this website is provided for general information only. It is not intended for use as a navigation aid. NOAA publishes the official navigation charts to be used in US waters by mariners. Any navigational use of this data by others than the Corps of Engineers constitutes misuse of the data. At best, hydrographic surveys are accurate only at the time they are measured and only within the tolerances of the survey equipment, computers, printers, and other tools and equipment used to produce and print them. Wind, waves, currents, and other maritime effects are constantly changing the topography of the waters of the United States. Survey equipment and computer plotting software have inherent inaccuracies, and printers and displays can also create inaccuracies.
