This ancient irrigation construction situated at Trincomalee District. According to the chronicles the Kanthale tank is also named as “Gangathala Vapi”. It was built by King Agbo the II (608-618) and rehabilitated and further developed by King Parakramabahu (1153 - 1186) the Great.
There is rich folklore on Kantale Wewa including tales in Tamil. The Dutch who controlled the coasts of Sri Lanka lent their attention to Kanthale Wewa. There are reports from the Dutch Period which show the rehabilitation work carried out by them. The British Governor Sir William Gregory also had commissioned reconstruction work at Kanthale Wewa.
Kanthale Tank bund was breached on 26th April 1986. It was a major challenge to the Irrigation Department which it faced successfully by restoring the bund within a short period of time. It was a disaster which emphasizes the importance of the Dam Safety.
