== Purpose ==
The purpose of the barrage is to divert of water from the Ganges to the Hooghly River for flushing out the sediment deposition from the Kolkata harbour without the need of regular mechanical dredging. After commissioning the project, it was found that the diverted water flow from the Farakka barrage was not adequate to flush the sediment from the river satisfactorily. In addition, there are regular land/bank collapses in to the Ganga river due to the high level back waters of the Farakka barrage. Substantial high land is already converted into low level river bed causing displacement of huge population.〔(【引用サイトリンク】title= The Encroaching Ganga and Social Conflicts: The Case of West Bengal, India. )〕 The water diverted from the Farakka barrage is less than 10% of Ganga river water available at Farakka.〔(【引用サイトリンク】title= Ganga river water flow data at Farakka, India. )〕 The Indian government is contemplating to cement line/widen/deepen the Farakka feeder canal to increase the flow.
