Nanu Oya
Nanu Oya is a 27 km (17 mi) long stream in the Central Province of Sri Lanka. It originates at an elevation of over 2,000 m (6,562 ft) on Pidurutalagala, the highest mountain in Sri Lanka, flowing into the Kotmale Oya at an elevation of approximately 1,200 m (3,937 ft). The Kotmale Oya is a tributary of the Mahaweli River, the longest river in Sri Lanka, which finally discharges at Trincomalee after a combined distance of nearly 350 km (217 mi). The river was dammed in 1873 to create the popular Lake Gregory in Nuwara Eliya.[1][2] The Nanu Oya discharges into the Kotmale Oya 2.5 km (1.6 mi) upstream of the Upper Kotmale Dam.
