The South Sudanese region of Bahr el Ghazal takes its name from the river.

The Bahr el Ghazal is the main western tributary of the Nile.

It is 716 km (445 mi) long, flowing through the Sudd wetlands to Lake No, where it joins the White Nile.

[1] The Bahr al Ghazal's drainage basin is the largest of any of the Nile's subbasins, measuring 520,000 km2 (200,800 mi2) in size, but it contributes a relatively small amount of water, about 2 m3/s (70 ft3/s) annually, due to tremendous volumes of water being lost in the Sudd wetlands.

[3] The river's drainage basin, including its tributaries, is 851,459 square kilometres (328,750 sq mi) and reaches west to the border of the Central African Republic and northwest to the Darfur region.
