The others, which terminate streams, are the Bahr el-Ateiba, which receives the waters of Damascus; the Mat, into which the Kuwaik flows below Kinnesrin; and the Ak Deniz, or Bahrat Antakia, the ancient Lake of Antioch, which collects the waters of the Kara Su and Afrin, the southward from the watershed which shuts off Commagene.
At the western end of the barrage begins the Ibrahimia canal, the feeder of the Bahr Yusuf, the largest irrigation canal of Egypt.
The modern Arabic name is Bahr Tubariya, which is often rendered "Lake of Tiberias."
In Upper Egypt the most important canals are the Ibrahimia and the Bahr Yusuf (the River of Joseph).
It now supplies the Bahr Yusuf, which runs parallel with and west of the Ibrahirnia, until it diverges to supply the Fayuma distance of some 350 m.
