The Inland Waterways Authority of India launched a new portal named 'Least Available Depth Information System' (LADIS) on 15 February 2019.

• LADIS will ensure that real-time data on least available depths is disseminated for ship/barge and cargo owners.
• This will help in better planning for the movement of ships.
• It will be available for NW-1, NW-2, Indo-Bangladesh Protocol route, and NW-3.
