The Canyon Dam is a large arch-gravity dam built across the Maskeliya Oya, 4.5 km upstream of the iconic Laxapana Falls, in the Central Province of Sri Lanka. The associated power station plays a major role in the national power grid, due to its significant output.
The dam is surrounded by steel structures of the substation.
