Glaw Lake, a pristine freshwater lake in Arunachal Pradesh's Eastern Himalayas, was designated as India's 101st Ramsar site on 3 August 2026, an announcement made by the Ministry of Environment, Forest and Climate Change. The designation also made Glaw Lake the first Ramsar site from Arunachal Pradesh, arriving just weeks after India had crossed the milestone century of Ramsar sites with the designation of its 100th site.

The lake sits at an elevation of 1,168 metres, nestled within the densely forested Kamlang Tiger Reserve and Wildlife Sanctuary, and is fed by perennial mountain streams. It is a recognised biodiversity hotspot, surrounded by lush vegetation that includes more than 150 tree species and 49 recorded orchid species within the site and its catchment area.

Beyond its ecological value, Glaw Lake holds deep cultural significance for the local Mishmi community, who regard it as sacred. The Ministry described the designation as an important step for biodiversity conservation, water and climate security, and sustainable livelihoods, and a site-specific restoration plan is being prepared to support the wetland's protection, with particular emphasis on the active participation of the Mishmi community in its sustainable management.
