The government has decided to set up a tribunal to resolve issues relating to the sharing of the Mahanadi river water between Odisha and Chhattisgarh, a senior water resources ministry official said.

Odisha has been demanding formation of a tribunal for a long time. It has argued that Chhattisgarh has been constructing dams and weirs (small dams) upstream, affecting the flow of the Mahanadi river considered as the "lifeline" on its territory.

"It has been decided to set up a tribunal to resolve issues relating to Mahanadi between the two states under the Inter-State River Water Disputes Act, 1956," the official said requesting anonymity as he is not authorised to speak to the media.

He said a draft cabinet note in this connection has been prepared.

Odisha Chief Minister Naveen Patnaik had taken up the issue of construction of barrages upstream by Chhattisgarh at a trilateral meeting convened by Union Water Resources Minister Uma Bharti on September 17, 2016.

He had complained the construction would affect drinking water supply and irrigation facilities in his state.

The meeting, also attended by Chhattisgarh Chief Minister Raman Singh, however, had failed to achieve any solution.

Odisha, again, approached the Centre on November 19 last year, demanding a tribunal be formed to adjudicate the matter.
