Kolong river

The Kolong River or Kailang is an anabranch of the Brahmaputra River, which diverts out from the Brahamputra river in Hatimura region of Jakhalabandha (Nagaon district, Assam, India), and meets the same at Kolongpar near Guwahati. The tributary is about 250 kilometres (160 mi) long and flows through the districts of Nagaon, Morigaon and Kamrup. On the way, several smaller streams (Diju, Missa River and others) meet it. The river flows through the heart of the Nagaon urban area, dividing the town into Nagaon and Haiborgaon.
