It receives the Waters of the canalized channels which were once the Tanitic, Mendesian and Pelusiac branches.
That part of the lake east of where the canal was excavated is now marshy plain and the Tanitic and Pelusiac mouths of the Nile are dry.
Farther east are other canals, of which the most remarkable occupy in part the beds of the Tanitic and Pelusiac branches.
That following the old Tanitic channel is called the canal of Al-Moizz, the first Fatimite caliph who ruled in Egypt, having been dug by his orders, and the latter bears the name of the canal of Abu-l-Muneggi, a Jew who executed this work, under the caliph Al-Amir, in order to water the province called the Sharkia.
It is built on a branch of the Fresh Water or Ismailia canal, and on the Al-Mo`izz canal (the ancient Tanitic channel of the Nile), and is 47 m.
