The following table lists most rivers of Sri Lanka. Since Sri Lanka is a trilingual country, some rivers may have a Sinhala name (i.e. Kalu Ganga), while other have an English name (i.e. Kelani River). There are two words meaning "river" in the Sinhala language, namely Ganga (ගඟ) and Oya (ඔය). 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. [1]
