Jonglei

Geography

Jonglei, which covers an area of 122,581 square kilometres (47,329 sq mi), forms the bulk of the eastern part of South Sudan covering most of the eastern centre. Located in the Greater Upper Nile region, it is bordered by Upper Nile State to the north, Unity State to the northwest and west, Lakes State to the southwest, Central Equatoria to the southwest, Eastern Equatoria to the south, and Ethiopia to the east.

The principal town, Bor, lies in the southwestern corner of the state. Other towns include Akobo, Ayod, Fangak, Padak, Pibor, Pochalla and Waat. The principal rivers are the White Nile, which flows in the western part of the state, and the Pibor River, which flows in the central-east. The Pibor and its tributaries drain a watershed 10,000 km² (3,900 sq mi) in size. The rivers mean annual discharge at its mouth is 98 m³/s (3,460 ft³/s). In the southern part of the state is the Kenamuke Swamp (Kobowen), a wetland which is part of the Boma National Park. In June 2007, Animal Geographic Magazine estimated that over 1.3 million animals lived in Boma National Park. It is "home to one of the largest migrations in the world with an estimated 800,000 white-eared kob antelope, 250,000 Mongalla gazelle and some 160,000 tiang moving across Jonglei State", according to the Wildlife Conservation Society.
