Walawe River Basin

June 14, 2026 claymatics.web@gmail.com Hambantota

Overview

The Walawe River drains the central highlands via the Uda Walawe reservoir and flows south through the dry zone lowlands of the Hambantota District to meet the Indian Ocean near Ambalantota. The lower Walawe River basin — the floodplain and river margin environment downstream of the reservoir — is one of the finest stretches of riverine wildlife habitat in the Southern Province. Mugger crocodiles are common along the sandy banks and pools of the lower river, elephants regularly cross the river in the vicinity of Udawalawe and use the floodplain areas, and the tall trees along the riverine forest margins provide nesting sites for large waterbirds including painted storks, open-billed storks, and various heron species. The river basin is accessible from the roads along its banks and from boats launched from several points along the lower reaches.
