Summary Statistics	Mahaweli Development Centre Giradurukotte ( System C )

System C is located on the Right bank of the Mahaweli Ganga, from the Minipe diversion structure to the confluence of the Maduru Oya. It embraces the upper portion of the irrigable area of the right bank in the central reaches of the Mahaweli and a smaller part of the left bank area of the Maduru Oya. A trans-basin canal from the Minipe anicut supplies the area with required irrigation water. The topography of the land is rather undulating and it is cut by Badulu, Loggal, Hepplola and Ulhitiya Oya, which are the four major tributaries of the Mahaweli on the right bank below Minipe. The total area under the system comprises 76,900 acres (in1967 sources) including 3,300 irrigated areas.

The system is surrounding Mahiyangana, the ancient city of religious significance are Mapakada Wewa, Dambara Wewa and Sorobora Wewa, the three irrigation schemes which at present supply water to 3,300 acres of land. This system ensures two crops per year. (in 1968 report)

System C was subdivided into 6 Zones. Zone 2 on the left bank was served by a 10 km long main canal providing irrigation water. Zone 1 is above the command of the Ulhitiya reservoir and the lands developed are under the command of the Mapakada, Dambarawa and Horabora reservoirs. Since the catchments areas of these small tanks are cut-off by the trans basin canal, water supplies are issued from the transbasin canal. The main canal serving Zone 2 and its tertiary canal system were constructed by medium and small scale contractors.

The rest of the 4 Zones of the right bank are served by the 17 km long main canal. (Funded by the Japanese Government) Over 90% of the development costs of system C were financed by many donor agencies. The Trans basin Canal and System C was commissioned in April 1983.
