Pimburattewa lake

Sri Lanka is renowned for its ancient irrigation systems and breathtaking natural beauty. While iconic sites like Sigiriya and Polonnaruwa draw crowds, there are countless lesser-known treasures scattered across the island, waiting to be discovered. One such gem is the Pimburaththewa Wewa Reservoir (Pimburattewa Wewa), hidden in Aralagamwila, 40 km off Polonnaruwa.

Situated 8 kilometres from Aralagamwila town, near the Maduru Oya National Park, the Pimburaththewa Wewa Reservoir has become a popular destination, largely due to its uniquely shaped, zig-zag spillway, constructed in the 1980s as part of the Mahaweli Development Project.

Spanning 2400 acres (9.7 square kilometres), the reservoir boasts a 1.2-kilometer-long embankment, with the spill located on its eastern side. During the rainy season, when the reservoir reaches capacity, excess water cascades over the spillway, creating a captivating spectacle.

This natural overflow attracts large crowds, both local and from further afield, who come to witness the impressive sight and enjoy bathing in the shallows beyond the spill.

Because of its proximity to Maduru Oya National Park, elephants frequently visit the reservoir, particularly in the evenings, seeking water. Visitors should therefore exercise caution due to the potential presence of these animals.
