Yoda Ela (Giant Canal) or Jaya Ganga, an long single banking water canal carrying excess water to Tissa Wewa reservoir from Kala Wewa reservoir in Anuradhapura.

Construction Yodha Ela was constructed during King Dhatusena's reign in 459 Anno Domini. It is long. It is a trans-basin diversion canal transferring water from Kala Oya River basin to Malvathu River Basin. It has a gradient of the order of drop along . Even with modern day survey equipment it would be difficult to achieve such accuracy.

Yodha Ela not only feeds Tissa Wewa, but also the nearby Abhayavapi and Nuwara Wewa. A separate branch of the canal has then already brought water to the Nachchaduwa wewa. Kala Wewa and Yodha Ela (Jaya Ganga) - An irrigation wonder of Ancient Sinhalese, AmazingLanka.com, retrieved 28 January 2022

Parakramabahu I who reigned the country from 1153 to 1186, expanded the area that contributed to the water in the canal by connecting more reservoirs to the network between Kala Wawa and Thissa Wawa. He then renamed it Jaya Ganga (River of Victory).

Functions 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 Acequia'. It feeds water in an area of feeding of Paddy field and 120 small tanks on its way from Kala Wewa to Tissa Wewa
