Navigation Notices

Welcome to Notices To Navigation Interests (NTNI) System

The Notices to Navigation Interests (NTNI) website contains Navigation and Policy Notices issued by the U.S. Army Corps of Engineers Districts with a waterway navigation mission. These notices are disseminated according to Chapter 2 of EP 1130-2-520 (PDF) to inform mariners of information describing events that affect waterway navigation such as maintenance projects, hazards to navigation, restrictions and other pertinent information.

The Navigation Notices are removed from the page seven days past the end date on the latest amendment. This site does not contain navigation notices published by other Federal agencies, such as the US Coast Guard Local Notice to Mariners website.
