The Mahaweli River is the longest river in Sri Lanka, stretching approximately 335 kilometers. It originates from the central highlands and flows through various landscapes, including lush forests and agricultural areas, before emptying into the Bay of Bengal. The river plays a crucial role in the country's irrigation and hydropower generation. The Mahaweli River basin is vital for the local economy, supporting farming and providing water for domestic use. Several major dams, such as the Victoria Dam and Kotmale Dam, are built along the river, contributing to energy production and flood control. The river is also home to diverse wildlife and ecosystems.
