Yoda Ela (Giant Canal) or Jaya Ganga, an 87 km (54 mi) long single banking water canal carrying excess water from Thisa wawa reservoir to Kala wawa reservoir in Anuradhapura. The Yodha Ela is known for achieving a rather low gradient for its time. The gradient is about 10 centimetres per kilometre or 6 inches per mile.
Yodha Ela was constructed during King Dathusena's reign in 459 AD. It is 87 km (54 mi) long. It is a trans-basin diversion canal transferring water from Kala Oya Basin to Malwathu Oya Basin, but because of the mild slope to which it had been constructed. Its mild-gradient had been found to be of the order of 0.32 m (1.0 ft) drop along 1.61 km (1.00 mi). Even with the modern day survey equipment achieve the said accuracy.
Yodha Ela functions in a way of a moving reservoir because of its single banking aspect which is different from the present day double banking irrigation canals'. It feeds water in an area of 470 km2 (180 sq mi) feeding 4,630 ha (11,400 acres) of paddy lands and 120 small tanks on its way from Kala Wewa to Tissa Wewa

The system was extensively restored and further extended during the reign of King Parākramabāhu.

An aqueduct is a watercourse constructed to carry water from a source to a distribution point far away. In modern engineering, the term aqueduct is used for any system of pipes, ditches, canals, tunnels, and other structures used for this purpose. The term aqueduct also often refers specifically to a bridge carrying an artificial watercourse. Aqueducts were used in ancient Greece, ancient Egypt, and ancient Rome. In modern times, the largest aqueducts of all have been built in the United States to supply large cities. The simplest aqueducts are small ditches cut into the earth. Much larger channels may be used in modern aqueducts. Aqueducts sometimes run for some or all of their path through tunnels constructed underground. Modern aqueducts may also use pipelines. Historically, agricultural societies have constructed aqueducts to irrigate crops and supply large cities with drinking water.
The Kandalama Reservoir is a reservoir in Kandalama, Sri Lanka. The reservoir is created by the 21 m (69 ft) high and 1,600 m (5,200 ft) wide Kandalama Dam.
