The source of the Nile is sometimes considered to be Lake Victoria, but the lake has feeder rivers of considerable size.

The two feeder rivers meet near Rusumo Falls on the Rwanda-Tanzania border.

The route they followed up the feeder river gradually turned northwest.

Kudali, Urmodi, Venna and Tarali are small feeder rivers (tributaries) of Krishna.

The feeder river, Walupt Creek, is sourced directly from Walupt Lake which provides a consistent flow throughout the year.

Dam construction on the lake's feeder rivers has produced major changes to the ecological balance of the lake and wetlands.

When they enter lakes, their sensitivity to the slightest movement in the water enables them to swim straight through into the feeder rivers.

Run-off from a salmon hatchery at the eastern end of the loch attracts large fish, including, unusually, charr, into its main feeder river, the Abhainn Mhòr.

Its feeder rivers are the upper King, Nelson, Princess, and Eldon Rivers.

It is unknown which of these two feeder rivers is the longer and hence the ultimate source of the Nile.
