History

Namdapha was originally declared a Wildlife Sanctuary in 1972, then a National Park in 1983 and became a Tiger Reserve under the Project Tiger scheme in the same year. Its name was a combination of two Singpho words, namely "nam" which means water, and "dapha" which means origin – the river originates from the Dapha Bum glaciers.
