Man made Lakes and Canals

The islands Buddhist civilization produced skills of hydraulic engineering capable of building some of the largest man made irrigation works in the world. Many still provide water to the thousands of acres of paddy fields an urban need. The skills of our engineers in this branch is clear from the historical evidence such as the invitation made to Sri lank an Engineers in the 8th century by a Kashmir kin to form a lake in his Country.

Our ancestors more than 3000 years ago has seriously considered this concept of water storing and delivery. It is evident from the gigantic reservoirs like “Parakrama Samudra”, “Kalawewa”, “Minneriya”…. etc and canal systems of Elahera, Yoda Ela…etc. Unfortunately due to he invasions since the Anuradhapura Era up to British period and epidemics caused all the development and technical skills of went in to wilderness. As a result Sri Lanka had to implement a new agriculture development program n the 19th century as a new enterprise.

Built in 5th century AD 44.25 hectares in extent Length and the size of the dam are 5.6 km and (13-19) m

Jaya Ganga (Yoda Ela)
This work of ancient Sri Lankan is considered as engineering wonder in irrigation. This stream is 54 miles long and constructed to supply water from Kalawewa to Thissa wewa in Anuradhapura. Evan Nowadays irrigation engineer’s wonder how the engineers of that era could manage to keep the slope of first 17 miles (27.2km) at 6cm per 1.6km (1 mile)

Parakrama Samudraya
Polonnaruwa boasted one of the largest and most spectacular of Sri Lanka’s ancient tanks, the ‘Parakrama Samudra’ or the Sea of Parakrama.
It was built by king Parakramabahu the 1st. One of the greatest of the Singhalese rulers. The bound of the Parakrama Samudra was nearly nine miles long and rose to an average height of 40 feet. Its 5,600 acres of water irrigate an estimated 18,200 acres of paddy land.
