Noadihang

The Noa-Dihing descends from the Patkai hills towards the upper Brahmaputra valley. The river country formed part of the route by which the Ahoms entered Assam from the east in the early thirteenth century. Crossing the Patkai through the Pangsau Pass, they advanced along the Noa-Dihing before establishing their kingdom farther west. Forested hills rise above the river, which joins the wider network of waters feeding the Brahmaputra.
