Assam is a water-rich state with extensive navigable waterways. The Brahmaputra and Barak are the longest and most important rivers in the state. They have numerous tributaries. The total length of the riverine system in the state is 4065 km, out of which 2194 km area navigable throughout the year and the rest during the monsoon only. The Government of India declared the river Brahmaputra from Dhubri to Sadiya as National Waterway No-2 on 1st September 1988. The Directorate of Inland Water Transport, Assam and CIWTC operate water transport services on a commercial basis through the river Brahmaputra and Barak.

Two Government owned organizations of Assam namely, Central Inland Waterways Corporation and Directorate of Inland Water Transport (IWT), operate the water transport services on the river Brahmaputra and Barak on a commercial basis. The Brahmaputra has several small river ports and more than thirty pairs of ferry ghats on the Brahmaputra transporting both passengers and cargo. However, owing to the scarcity of serviceable vessels under the department most of the ferry services often suffer problems in their smooth operation. Currently, the Directorate of Inland Water Transport is operating 85 (eighty-five) ferry services under 3(three) IWT Divisions on the river Barak, the Brahmaputra and its tributaries.
