The Dakatia is the first tributary that the Meghna receives after entering Noakhali. It combines several hill streams, including Sonaichari, Pagli Boaljar, and Kakri, originating from the Tippera Hills. After traveling about 6 miles in the south, it splits at latitude 230.21" and longitude 910.31 '^{[needs update]}. The left branch follows a sinuous course in the south until it meets little Feni River, while the right branch flows southwest and northwest up to Hajiganj, where Boaljuri river meets it on the right bank. Before taking an abrupt turn to the south about 15 miles further, the river throws off a channel, known as Chandpur Nullah that falls into the Meghna. The river follows a meandering course, dropping into Meghna at Hazimara.

The Dakatia was formerly an important trade channel. It is still navigable in the lower region during the monsoon. The upper region is navigable throughout the year. The three gauging stations, at Hajiganj, Raipur, and Hazimara.
