Experts Survey Uttarakhand Glacial Lakes for Disaster Risks
Expert teams are studying two high-altitude lakes in Uttarakhand.
The lakes are called Saraswati Tal and Kedartal.
Scientists will check how much water they hold and whether their size or surroundings have changed.
They will also study what could happen to areas downstream if a lake becomes dangerous.
Uttarakhand says 13 glacial lakes are sensitive, and four have already been surveyed.
The teams include scientists, disaster-response workers and mountaineering experts.
Their findings will help officials create better warning systems and evacuation plans.
The goal is to reduce harm if a glacial lake creates a disaster.
Teams are surveying Saraswati Tal in Chamoli and Kedartal in Uttarkashi.
The surveys will measure water levels, lake conditions, size changes, terrain and downstream risks.
Uttarakhand has identified 13 sensitive glacial lakes, with four already surveyed.
Bathymetric surveys will be conducted at elevations of about 5,700 and 4,750 metres.
Officials plan to improve early warnings, evacuation routes, communications and rescue preparedness.
