Southwestern Sri Lanka Rivers And Streams
Southwestern Sri Lanka rivers and streams is a freshwater ecoregion in Sri Lanka.

The ecoregion spreads over 15,500 km2 in the wet zone of the southwestern part of Sri Lanka. More than a quarter of the freshwater fishes that have been discovered in Southwestern Sri Lanka rivers and streams are endemic.
