The concern of Ganga drying up has emerged because the inflow of Ganga at the Farrake barrage in West Bengal has reduced to historically low. This has resulted in shutting up of NTPC hydro-electricity plant .
Reasons for reduction in the flow:
- Tampering with the flow of Ganga in the upper reaches on account of construction of dams
- Encroachment of flood plans
- Melting of Glaciers of tributaries of Ganga
- Deficieny in rainflall in recent years
