The Ganga River—once hallowed as a lifeline, spiritual symbol, and cradle of civilization—is subtly disappearing. Not through over-extraction or pollution itself, but through an insidious and highly troubling process: evaporation. A new study by IIT Roorkee (August 2025) has a startling revelation—Ganga river loses over 50 percent of its water before it even enters the plains, not via diversion or dams, but to the atmosphere. More astonishing is that it’s not glacial melting that keeps the river going in lean months, but groundwater. This turns myth on its head and highlights a quiet crisis in plain sight.
Ganga River Loses Over 50 Percent of Its Water: Impacts on Cities
This evaporation-driven loss, combined with low levels of groundwater, portends a bleak future for more than 400 million people reliant on the river. When the Ganga gets thinner, the cities of Varanasi and Patna will suffer severe water scarcity. The lowered flow of the river undermines its power to flush out polluters, and hence species such as the endangered Gangetic dolphin will swim in water contaminated with more than 39 hormone-disrupting chemicals. Farmers throughout Uttar Pradesh and Bihar now have another variable they can’t count on: a river that might not show up when it’s needed most.
But this crisis has been largely unremarked upon. Unlike a flood or a dam break, this is not a disaster that calls for attention. It’s a silent vanishing—occurring through subtle shifts in satellite imagery, not television reports. No dramatic footage. No viral seconds. Just a soft, steady erasure.

A River to Save, A Responsibility to Share
But there is a way forward—and it starts with awareness and action. The study demands urgent action: aquifer recharge via rainwater harvesting and reforestation, conservation of tributary streams and wetlands that feed the river, and preservation of environmental flows, guaranteeing regulated water release from dams to keep the river alive. Most importantly, it demands a shift in thinking. The Ganga should not be viewed as merely a utility pipeline, but as a living ecosystem—deeply entwined with climate, people, and culture.
This crisis also calls for a deeper, more intimate self-reflection. For some, including the author, the Ganga is a part of childhood and sacred practice—a river that was once considered timeless. But timelessness, it now appears, must be watched over. In this era of climate alarm, worship must change into stewardship. Piety, into action.

The Ganga is not lost yet. But she is disappearing. If we just keep on ignoring her gradual vanishing, we stand the risk of not only losing a river, but an entire way of being.
Now is the time to observe, to act, and to conserve.
