Sembuwatta Lake is a scenic man-made reservoir situated in Elkaduwa Estate, in the Matale District of Sri Lanka's Central Province. Located at approximately 1,084 metres above sea level, the lake is surrounded by beautiful tea plantations, pine forests and green mountain landscapes. Its cool climate and peaceful atmosphere make it an attractive destination for visitors seeking relaxation and outdoor experiences.
The lake was originally constructed around 1945 during the British colonial period as a reservoir to support the operations of the nearby tea estate and its hydroelectric power system. The area was later developed into a tourist destination, with visitor facilities introduced around 2005–2006.
The name Sembuwatta is associated with local folklore about a brass pot, known as a Sembuwa, reportedly discovered near a natural spring in the area. The lake is fed by natural spring water and is approximately 9–12 metres deep.
Today, Sembuwatta Lake is managed by Elkaduwa Plantations and offers recreational facilities and beautiful natural surroundings. Visitors can enjoy the scenery, explore walking paths, take photographs and experience the cool mountain environment. A separate natural spring-water swimming pool is also available in the area; swimming in the main lake itself is unsafe and should be avoided.
