A view of Captai Lake

Famous Kaptai Lake, the largest "man-made" lake, spreading over 680 sq. km. of crystal-clean water flanked by hills and evergreen forests lies in the Rangamati Hill District. The lake was formed when the Karnaphuli river dam (153 feet high, 1800 feet long crest) was built for the purpose of hydroelectric power project at Kaptai.
