Kaudulla Wewa
Kaudulla is a reservoir, an irrigation wonder of the 3rd century with a capacity of 64 million cubic meters, which was constructed by King Mahasen. It has two natural water reservoirs, such as Gal Oya and Aluth Oya. Kaudulla Wewa is a 9235m long embankment (bund), is one of the longest in this country, and has a height of 15m and width of 120m. Kaudulla is also identified as the “Thissawaddamana Vapi” and “Ranthisa Wewa.” King Vijayabahu and King Parakramabahu did renovation work and even built a bund across Kaudulu Oya. These details are stated in the historical records of Sri Lanka. It receives water along the Elahera-Kantale Giant Canal, which begins from Elahera Anicut on Amban Ganga, built by King Vasabha.
This vast reservoir is surrounded by the attractive Kaudulla National Park, an important bird area of the nation.
