Udawalawa Reservoir

About Udawalawa Reservoir

The Udawalawa Reservoir is one of the largest man-made reservoirs in southern Sri Lanka, created by damming the Walawe River. Completed in 1969, it plays a vital role in irrigation and hydroelectric power, but it is also a stunning natural attraction in its own right. The reservoir adds immense beauty to the region with its wide waterscape surrounded by hills, forests, and grasslands. It forms a core part of the Udawalawa National Park ecosystem, attracting wildlife and birds throughout the year.

Location

The Udawalawa Reservoir is located adjacent to Udawalawa National Park, just a short distance from many of the area’s lodges and resorts, including the Imperial Resort Udawalawa. It’s easily visible during safaris and accessible for peaceful strolls or short stops.

Things to See

While the reservoir itself is not a tourist site with dedicated facilities, it offers scenic beauty and is a key spot for wildlife observation, especially:

Elephants coming to the edge to drink and bathe

Water birds such as herons, storks, egrets, and kingfishers

Stunning sunrise and sunset reflections on the still water

Occasional views of crocodiles and buffaloes resting near the banks

You can enjoy views of the reservoir during a safari inside the national park or visit Udawalawa Dam, which offers panoramic views of the landscape. It’s also a popular stop for photographers and nature lovers looking for peaceful scenery.

Best Times to Visit

Early morning and late afternoon are ideal for visiting the reservoir, both for cooler weather and better chances of spotting wildlife. The dry season (May to September) typically offers clearer views and better lighting for photography.
