Lunugamwehera National Park is the immediate catchment of Lunugamwehera reservoir.
The park serves as a link between the Yala Protected Area Complex on its east and Udawalawe National Park to its west and facilitates the ranging of elephants to and from areas such as Haldummulla and Koslanda in Uva and the southern region of Sri Lanka.
Lunugamvehera National Park in Sri Lanka was declared in 1995, with the intention of protecting the catchment area of the Lunugamvehera reservoir and wildlife of the area. The national park is an important habitat for water birds and elephants. The catchment area is vital to maintain the water levels of the five tanks in the down stream of Kirindi Oya and wetland characteristics of Bundala National Park. This national park also serves as a corridor for elephants to migrate between Yala National Park and Udawalawe National Park. The national park is situated 261 km (162 mi) southwest from Colombo. After being closed because of the Sri Lankan civil war, the national park is now open to the general public.
