The lake was created as a result of building the Kaptai Dam on the Karnaphuli River, as part of the Karnaphuli Hydro-electric project. The Kaptai Lake's average depth is {{convert|100|ft|m}} and maximum depth is {{convert|490|ft|m}}. HistoryConstruction of the reservoir for the hydro-electric plant began in 1956 by the Government of East Pakistan.[2] As a result, {{convert|54000|acre|km2}} of farmland in the Rangamati District went under water and created the lake. The hydro-electric project was funded by the United States. The project was finished in 1962. International Engineering Company and Utah International Inc. received the contract for construction of the dam. The dam is 670.8 meters long, and 54.7 meters high. The dam has a {{convert|745|ft|m}} long spillway containing 16 gates. Through the spillway {{convert|5250000|cuft/s|m3/s|abbr=on}} of water can pass. The land that went under water as a result of the dam construction, was 40% of the total arable land in the area. Along with that, {{convert|29|sqmi|km2}} of the Government-owned forest, and {{convert|234|sqmi|km2}} of other forest land went under water. About 18,000 families with a total of almost 100 thousand people were also displaced. The palace of the king of the Chakmas was also flooded and is now under water.[2] Ecological disasterThe ecological damage of the lake recently assessed shows that water pollution due to the use of fertilisers and pesticides around the lake is affecting life in the water. In 1966, the share of big fishes in the total fish production was 78%, by 1993 it had come down to 2%. Also, more than five tons of human excrements and other wastes are reported to flow into the lake every day. As 85% of the population living around the lake depends on the water for drinking, cooking, washing and bathing, health risks have increased sharply. GallerySee also
