The Govt. of Odisha had reported that Chhattisgarh had started many projects upstream of Hirakud Dam, which would have long term effect on the flow downstream especially during the lean period. The effect of ongoing projects upstream of Hirakud on long term flows downstream in Odisha will result as retain of the major portion of the non-monsoon flow of water and will also affect ecologically sensitive Coastal and delta area of Mahanadi. As such, Govt. of Odisha has urged that the Government of Chhattisgarh should stop work of all ongoing projects for three months.
In view of the above, Ministry of Water Resource, RD & GR has convened two meetings viz. 29.7.2016 and 17.09.2016 to consider various water resources issues in Mahanadi Basin.
