The Sankh River flows across Jharkhand, Chhattisgarh and Odisha states in India. The river flows for 240 km before it meets the Koel River in Odisha.

Course

The river starts 1000 m above sea level in Lupungpat village in Gumla district in Jharkhand and flows 67.5 km in the state before entering Chhattisgarh. It runs a distance of about 50 km in Chhattisgarh and enters Jharkhand again to flow for another 78 km. The river finally enters Odisha and travels another 45 km before merging with the Koel. The South Koel enters Odisha and joins the Sankh River at Vedavyas near Rourkela from where it is called the Brahmani (see 22.24588°N, 84.78375°W).
