Published by Office of Coast Survey | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: April 11, 2026 at 09:56 PM | Dataset Last Updated: December 01, 2015 at 12:00 AM
This layer shows coastal channels and waterways that are maintained and surveyed by the U.S. Army Corps of Engineers (USACE). These channels are necessary transportation systems that serve economic and national security interests. The possibility of silting is always present. Local authorities should be consulted for the controlling depth. NOS Charts frequently show controlling depths in a table, which is kept current by the US Coast Guard Local Notice to Mariners.
