text: Geography The enclave had an area of about , a population of about 250,000 and had its capital at the town of Lado which is near to the modern-day city of Juba. Under the 1894 Anglo-Congolese Treaty, the enclave's territory was dictated as "bounded by a line starting from a point situated on the west shore of Lake Albert, immediately to the south of Mahagi, to the nearest point of the frontier defined in paragraph (a) of the preceding Article. Thence it shall follow the watershed between the Congo and the Nile up to the 25th meridian east of Greenwich, and that meridian up to its intersection by the 10th parallel north, whence it shall run along that parallel directly to a point to be determined to the north of Fashoda. Thence it shall follow the thalweg of the Nile southward to Lake Albert, and the western shore of Lake Albert to the point above indicated south of Mahagi."
  A landlocked territory, it was bordered on the north by the Anglo-Egyptian Sudan province of Bahr-el-Ghazal and on the east by the Nile. The shifting sandbanks of the Nile led to islands on the border of the enclave and the Sudan regularly created or destroyed and made navigability difficult.
  Described variously as "a small muddy triangle along the Nile, ... a chain of desolate mudforts" and "shaped like a leg of mutton".
