Bhubaneswar: The Chhattisgarh Government has built around 516 check dams in the upper catchment areas of Mahanadi river to obstruct flow of water from the river to Hirakud reservoir.

Replying to a question, the Minister said that the neighboring State has built around 516 barrages to check inflow of Mahanadi river water into Hirakud dam. The inflow of water has considerably dropped during non-monsoon season due to construction of barrages by Chhattisgarh, he added.
