Top 6 in Top 9 Longest Rivers in Bulgaria
The Osam is a river that flows across northern Bulgaria. Its drainage basin is sandwiched between the Vit River's west bank and the Yantra system's east bank. In its upper course, the river has two main tributaries: the Black Osam originates at the foot of Levski Peak in the Balkan Mountains, at an elevation of 1,821 m (5,974 ft), and the White Osam originates on the northern slopes of the Kozya Stena peak.
The black and white Osam unite in Troyan. It flows north towards Lovech, then north-east until Letnitsa and Levski, then north-west until it meets the Danube 5 kilometers west of Nikopol. The river was once known as Assamus.
