Karnaphuli River
The Karnaphuli River is the most significant waterway in southeastern Bangladesh, originating in the Lushai Hills of Mizoram, India. It flows through the Chittagong Hill Tracts before emptying into the Bay of Bengal near the city of Chittagong. The river is of paramount strategic and economic importance as it hosts the Port of Chittagong at its mouth, which handles over 90 percent of Bangladesh's international maritime trade. In the 1960s, the country's only hydroelectric dam was constructed at Kaptai, creating the massive Kaptai Lake and providing a substantial portion of the national electricity supply. Ecologically, however, the river is under severe stress due to industrial discharge and heavy shipping traffic, leading to significant pollution levels. Recent years have seen major dredging initiatives to maintain navigability for large container vessels. The completion of the Bangabandhu Sheikh Mujibur Rahman Tunnel beneath the Karnaphuli marks another significant infrastructural milestone aimed at enhancing regional economic connectivity.
