Leko
Leko belongs to the Batang Hari Leko river country of southern Sumatra. The river is one of the tributaries that join the Musi as it flows east towards Palembang and the Bangka Strait. Forest and river channels cover the surrounding lowlands, and smaller streams feed the main course. Like the neighbouring Rawas and Lakitan, the Leko links inland lands to the great Musi basin, whose waterways gather the drainage of much of southern Sumatra.
