As part of Mahaweli Development programme, the river and its tributaries are dammed at several locations to allow irrigation in the dry zone, with almost 1,000 km 2 (386 sq mi) of land irrigated. [5] The production of hydroelectricity from six dams in the Mahaweli system supplies more than 40% of Sri Lanka's electricity needs.

There are two words meaning "river" in the Sinhala language, namely Ganga (ගඟ) and Oya (ඔය), of which the usage of both terms is arbitrary. At 335 km (208 mi), the Mahaweli River is the longest river on the island, its drainage basin covering more than one-fifth of the island. It is estimated that there are 103 rivers in Sri Lanka.
The main purposes of carrying out the program were the generation of hydroelectric power, controlling flood, making irrigation facilities for dry zone cultivation, settlement of landless and unemployed families by constructing and developing the physical and social infrastructure required for human habitation by using the waters of the Mahaweli River.
Victoria Dam (Sinhala: වික්ටෝරියා වේල්ල Viktoriya Vella) is an arch dam located 130 mi (209 km) upstream of the Mahaweli River's mouth and 4 mi (6 km) from Teldeniya in Sri Lanka. It is named in honour of Queen Victoria of the United Kingdom. Its main purposes are irrigation and hydroelectric power production.
The park's elevation range from 20–60 metres (66–197 ft) with sparse rock outcrop. [3] The Mahaweli River flows from south to north through the centre of the park. The rich alluvial soil flood plains situated beside the river are featured by a number of shallow swampy depressions called "villus".
Hydroelectricity accounts for nearly half of the installed power capacity of Sri Lanka. The following page lists most dams in Sri Lanka.Most of these dams are governed by the Mahaweli Authority, while the Ceylon Electricity Board operates dams used for hydroelectric power generation.
