Hydropower projects should remove water from the river by making a partial obstruction so that upstream migration of fish and downstream flow of sediments is unaffected.
Tehri Dam must be decommissioned. Monsoon water must by stored in groundwater aquifers in the plains.
Volumetric pricing of water must be done for irrigation. The price of agricultural produce must be increased to compensate the farmer for this additional burden.
All industries must be required to make Zero Liquid Discharge. Municipalities must be required to use treated sewage for irrigation.
