The Polavaram Project is an under-construction multi-purpose irrigation project on the Godavari River in the Eluru District and East Godavari District in Andhra Pradesh, India. The project has been accorded National Project status by the Central Government of India. Its reservoir back water spreads up to the Dummugudem Anicut (i.e. approx 150 kilometres (93 mi) back from Polavaram dam on main river side) and approx 115 kilometres (71 mi) on the Sabari River side. Thus, back water spreads into parts of Chhattisgarh and Odisha States. Polavaram Hydroelectric Project (HEP) and National Waterway 4 are under construction on left side of the river. It is located 40 kilometres (25 mi) upstream of Sir Arthur Cotton Barrage in Rajamahendravaram City and 25 kilometres (16 mi) from Rajahmundry Airport.
