The Samanalawewa Dam is a major hydroelectric project in Sri Lanka, located on the Walawe River in the Sabaragamuwa Province. Standing at 100 meters, it is the second-highest dam in the country, creating a massive reservoir primarily used for power generation. The power station has an installed capacity of 120 megawatts and provides a significant contribution to the national energy grid. Construction was completed in 1991 with international assistance, particularly from Japan and the United Kingdom. Geologically, the project has faced substantial challenges as the dam was built on permeable limestone terrain, leading to significant water leakages since its initial filling. Despite numerous remediation attempts, the leak continues, though the escaping water is utilized for downstream agricultural purposes. The reservoir is also known for its scenic location amidst rugged mountains, making it a destination for nature tourism. Samanalawewa remains a prime example of the complexities involved in large-scale infrastructure projects in geologically sensitive zones in Sri Lanka.
