Expanding Glacial Lakes Raise Flood Risk in Himachal Pradesh
What Happened
"Scientists and disaster-management authorities have expressed concern over the rapid growth of glacial lakes in Himachal Pradesh, driven by glacier retreat and changing snowfall patterns. Studies show that the size of many glacial lakes has increased by about 44% over the past three decades, while authorities have identified 67 vulnerable lakes that require close monitoring. The government is conducting detailed studies on several high-risk lakes and working to establish early warning systems.
Key Takeaways
Larger glacial lakes increase the risk of Glacial Lake Outburst Floods (GLOFs), which can unleash sudden floods, damage infrastructure, and threaten downstream communities. Experts say continuous monitoring, satellite surveillance, and early warning systems are crucial to reducing risks in vulnerable districts such as Kinnaur and Lahaul-Spiti.
