Kopili River 

  • The River Kopili is one of the important major tributaries of the Brahmaputra on its left bank.  

  • It originates from the Saipong Reserve Forest situated in south east of Meghalaya and passes through the borders of Meghalaya, North Cachar hills and karbi anglong and enters the plains in Nagaon district of Assam and finally joins the Brahmaputra at Kopilimukh. 

  • The Kopili Hydro Electric Project is built on this river by North Eastern Electric Power Corporation (NEEPCO). 

  • The river has been severely polluted by acid mine drainage from coal mining in Meghalaya (especially rat-hole mining), affecting aquatic life and water quality.
