The Ogan River is a river in South Sumatra, Indonesia. [1] It is a tributary of the 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 the Musi at Kertapati, Palembang. [2] The Ogan ranks as the third longest river in South Sumatra (behind Musi and Komering). The river either borders or flows through the regencies of South OKU, OKU, OKI, and Ogan Ilir.

Contents

The Ogan and Pegagan tribes 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.

Geography

The river flows in the southern area of Sumatra with predominantly tropical rainforest climate (designated as Af in the Köppen–Geiger climate classification). [3] The annual average temperature in the area is 24 °C. The warmest month is October, when the average temperature is around 26 °C, and the coldest is January, at 22 °C. [4] The average annual rainfall is 2902 mm. The wettest month is November, with an average of 435 mm rainfall, and the driest is August, with 83 mm rainfall. [5]

The Musi River is a river in Southern Sumatra, Indonesia. It flows from south-west to north-east, from the Barisan Mountains range that form the backbone of Sumatra, in Kepahiang Regency, Bengkulu Province, to the Bangka Strait that forms an extension of the South China Sea. The Musi is about 750 kilometers long, and drains most of South Sumatra province. After flowing through Palembang, the provincial capital, it joins with several other rivers, including the Banyuasin River, to form a delta near the town of Sungsang. The river, dredged to a depth of about 6.5 meters, is navigable by large ships as far as Palembang, which is the site of major port facilities used primarily for the export of petroleum, rubber and palm oil.
