The lake is bounded on three sides by mountain peaks covered with thick bamboo forests. The area of the lake is 18.56 acres (75,100 m2). It is a closed lake and there is a small spring named Boga chhara, which is 153 metres (502 ft) deep. There is no outlet for draining out water from the lake. The lake is composed of the soft rocks of the Bhuban Formation. The main source of water is the rain in summer.
The water is greenish due to the abundance of algae. The lake's bed is covered with boulders, like any other hill surface in that area. The lake's water was the only source of water for drinking, washing and bathing until 2012. Later, a pipe network was setup to bring stream water for drinking and household activities.
