Himachal Pradesh has identified 67 vulnerable glacial lakes above 10 hectares.
Early warning systems are planned for four high-risk sites in Kinnaur and Lahaul-Spiti.
Officials say satellite imagery and scientific analysis are being used to monitor glacial lake outburst flood risk.
The state says installing sensors in remote high-altitude areas is difficult, so it is working with the Centre for Development of Advanced Computing.
Why it mattersMapping vulnerable glacial lakes can speed alerts and reduce disaster risk for downstream communities.
