Nature has once again unleashed its formidable force in Uttarakhand's Harshil. Heavy rainfall and landslides have significantly altered the flow of the Bhagirathi River. A river that once flowed freely has now transformed into a vast reservoir in Harshil. This change not only impacts the army camp but also escalates potential danger for the entire region. Let's delve into the situation and understand why it’s cause for concern.
A Significant Shift in Bhagirathi's Flow
The flow of the Bhagirathi River in Harshil has altered dramatically. Torrential rainfall and debris from mountainous regions have obstructed the river's path, leading to a reservoir approximately 3 kilometers long. This reservoir formed at the site where an army camp had washed away. Debris has acted as a natural dam in the river, causing water to accumulate and increasing regional risks.

Impact on Army Camp and Highway
The reservoir has grown so vast that several sections of the army camp have submerged. Moreover, the Dharali-Harshil highway has also been inundated, completely severing road connectivity. Military and relief teams, already struggling with landslides and floods, now face exacerbated challenges from this newly formed reservoir. The area where the army camp once stood is now overwhelmingly waterlogged.
The Natural Dam of Debris
Scientists and locals believe that debris from the mountains has obstructed Bhagirathi's flow. This debris settled amidst the river, forming an invisible barrier that works as a makeshift dam. Consequently, water backs up, creating a substantial reservoir. Despite the river's onward flow, the accumulated water may pose a threat at any moment.

Potential Hazards
This reservoir could spell new trouble for Uttarakhand. Should the debris-induced dam break or if water pressure intensifies, the risk of flooding will escalate. Villages like Dharali and Harshil, already suffering from floods and landslides, face heightened threats. Vigilance by the army and administration is crucial to avert potential disasters.
Possible Causes?
Recent persistent rains and mountain instability are believed to be primary causes of these changes. Climate change has shifted rain patterns, increasing landslides and debris falls. This heightens the risk of river course alterations and reservoir formations.

Relief and Rescue Efforts
The Indian Army has been actively involved in relief and rescue operations in Uttarakhand. Following the formation of the reservoir in Harshil, helicopter and rescue teams have been deployed by the army. Yet, submerged roads and rising water levels complicate their mission. The local administration and army are collaborating intensely to manage the situation.
