Which Indian state celebrates the Chandubi Festival, as reported in the news recently?

The Chandubi Festival, an annual five-day event, happened recently in Assam beside the Chandubi Lake. This cultural extravaganza, which opens on the first day of the New Year, features boating among other activities along with the rich local folk culture, ethnic food, traditional handloom and clothing. Promoting ecotourism in Assam, a biodiversity hotspot, and addressing Chandubi Lake's diminishing water level are two important goals of the festival. It is not only important for maintaining the water body, but it also provides employment for a number of tribes, such as the Rabhas, Garos, Gorkhas, and tea tribes, who sell regional food, handcrafted drinks, and traditional clothing at the event.
