The estimated cost of the project is Rs.5,000 crore (Rs.50 billion).

Yadav said the move is likely to jeopardise the proposed power plants in the state as they would not get water clearance till they constructs their own reservoirs.

'It is bound to hit proposed power plants in the state. We fail to understand the centre's attitude towards Bihar's development,' he said.

'We have decided to write a letter to the central government and would take legal recourse if Bihar is prevented from using water of the Ganga for its power plants,' Yadav said.

The minister added that Bihar would take the help of states like Assam to lodge a joint protest with the central government over the issue.
