The park was designated on 9 November 1983.Providing a sanctuary to wildlife, especially for elephants and protecting the immediate catchments of five reservoirs are the importance of the park. A community of Vedda people, the indigenous ethnic group of Sri Lanka lives within the park boundary in Henanigala.The park is situated 288 kilometres (179 mi) north-east of Colombo.
An ancient sluice on the old ruptured earthen bund of the Maduru Oya was discovered in the 1980s.The sluice made up of stone slabs and bricks, is about 30 feet (9.1 m) high, 30 feet (9.1 m) wide and 219 feet (67 m) long. The upper sluice was built in two phases, the first of which dates to before the 6th century BC. The lower sluice is believed to be older than that.
