Ogan River is a river in South Sumatra, Indonesia.[1]
The Ogan River is a tributary of Musi River in Southern Sumatra. Flowing entirely in the South Sumatra province, it rises in Barisan Mountains (Bukit Barisan) and meanders slowly eastwards to join Musi River at Kertapati, Palembang.[2] The Ogan ranks as the third longest river in South Sumatra (behind Musi and Komering). The river either borders or cuts through the regency of South OKU, OKU, OKI, and Ogan Ilir.
Ogan and Pegagan tribe lived along the Ogan and its tributaries. Most were peasant or merchant. The river served first as vital transportation artery and communications link. Formed from thick layers of this river's silt deposits, the Ogan River Valley is one of the most fertile agricultural regions of the province.
