Four hydro projects violate Ganga flow norms
Since the government made it mandatory for hydro power projects on the upper reaches of the river Ganga’s tributaries to release minimum quantities of water through the year, 4 of the 11 projects are flouting norms, says a report by the Central Water Commission (CWC).
The ecological flow, or e-flow notification as it is called, specifies that the upper stretches of the Ganga — from its origins in the glaciers and until Haridwar — would have to maintain: 20% of the monthly average flow of the preceding 10-days between November and March, which is the dry season; 25% of the average during the ‘lean season’ of October, April and May; and 30% of monthly average during the monsoon months of June-September.’
