Nara Canal

paleochannel of the Indus which received water from the Ghaggar-Hakra until the Hakra dried-up, early 2nd millennium BCE.

[2] The Nara is the longest canal in Pakistan, running for about 226 mi (364 km).

[3] Within the Khairpur District, the canal and its associated wetlands were made into the Nara Game Reserve in 1972.

Before the construction of the Nara canal, the Indus River used to overflow in Bahawalpur and Sind Province above Rohri and the spillovers used to enter the Nara River.

The Nara Canal drains in to Shakoor Lake before overflowing into Kori Creek of the Great Rann of Kutch.

Nara Canal originates from Sukkur Barrage , Eastern bank of Indus River and runs through the Thar Desert . See also this satellite image.
