Boga Lake
Chattogram
Boga Lake is a natural deep freshwater lake located in the Ruma Upazila of Bandarban district in Bangladesh. Situated at an elevation of approximately 1,246 feet (380 meters) above sea level, the lake covers an area of about 18.56 acres (75,100 m²). Surrounded on three sides by mountain peaks and dense bamboo forests, the lake features a greenish water color due to abundant algae. It is a closed lake with no natural outlet, fed primarily by summer rainwater and a deep spring known as Boga Chhara. Historically, the lake's water was too acidic to support life until the mid-1990s, when plants and fish, including Tilapia, began to flourish, supporting local fishing practices by the Bawm tribe who settled nearby. The lake's bed is rocky, composed of soft Bhuban formation rocks with boulders typical of the hill terrain. Until 2012, the lake served as the primary source of water for drinking, washing, and bathing for local inhabitants, after which a piped stream water system was introduced. Boga Lake is not only a natural marvel but also steeped in local legend, enhancing its cultural significance in the region.
