Dumboor Lake is located in the Amarpur sub division, about 120 km away from the capital city of Agartala. It is shaped like a tapered drum and thus has been named after the damroo (small tapered percussion instrument) of Lord Shiva. This place is no less than a paradise for nature lovers as it is spread across an area of 41 sq km and is surrounded by 48 small islands lined by beautiful hills and lush green landscape. It lies at the confluence of Rivers Raima and Sarma and is home to various species of migratory birds, visible mostly during the winters. Near the lake is a Hydel Project, from where River Gomati originates. It is called Tirthamukh and is popular for the Pous Sankranti Mela that takes place here annually on January 14.
