Reservoir history
According to Mahavamsa, the tank was built by king Aggabodhi II of Anuradhapura and further developed by King Parakramabahu the Great. It was also known as Gangathala Vapi at the time. The reservoir has a catchment area of 216 km2 (83 sq mi) and a capacity of 135 million cubic metres (4.8×109 cu ft).
1986 dam failure
On April 20, 1986 (1986-04-20) at 03:00AM, the dam breached, sending a wall of water over the villages downstream. The floods killed approximately 120-180 people, destroyed over 1,600 houses and 2,000 acres of paddy, affecting over 8,000 families. One of the main causes of the breach was said to be due to extra-heavy vehicles being driven over the dam.
