National wetland atlas: high altitude lakes of India

This atlas contains maps and statistics on the High Altitude Lakes (HALs) found exclusively in the Himalayan region at an altitude above 3000 m above mean sea level. These are very special wetlands and play significant role in the hydrological cycle and water resources of Indian subcontinent, and harbors unique biodiversity. However, very little scientific information is available for the most of the Himalayan High Altitude Lakes due to the remoteness, harsh climatic condition and inaccessibility of the terrain of the region.
