Jampani river originating in Bhutan and Bhairabi river originating in Arunachal Pradesh meets here to form Dhanshiri River. Dhanshiri river is a major tributary of Brahmaputra river on its north bank. An irrigation project has been constructed on Dhanshiri river at Bhairabkunda. A guide dam has been constructed inside Bhutan for this project. The construction of the project took much more time than planned due to destructive current of the river and later on terrotist problems. The Project is situated in Udalguri district now within jurisdiction of Bodoland Territorial Autonomous District (B.T.A.D.) aimed to provide assured Irrigation to an area of 41.683 Hect. in five development blocks viz. Udalguri, Rowta, Kalaigaon, Mazbat and Bechimari under Udalguri Civil Sub-Division.
The Project has also the provision of power generation of total 20 MW capacity out of 5 No. falls of each 9.0M. drop. The revised estimated cost of the project is 401.24 crores. Physically 70% of the work has been completed and targeted to complete the balance work by 2010.
