The Jewel of Sindh: The Great Manchar Lake of Dadu

Lake Manchar is the largest freshwater lake in Pakistan and one of Asia's largest. It is located west of the Indus River, in Dadu District, Sindh. The area of the lake fluctuates with the seasons from as little as 350 km² to as much as 520 km². The lake collects water from numerous small streams in the Kirthar Mountains and empties into the Indus River.

It is located in Dadu.

Being a natural
storage it was free from the defects and drawbacks of an artificial
storage. Manchar Lake has been substantially supporting various economic
activities. It provided a livelihood for a large number of fishermen,
irrigation water for various crops and aquatic plants including lotus.
The lake could have also contributed a lot in boosting up tourism
industry if its beautification was properly maintained. However due to
various reasons the primitive beauty and usefulness of the lake have
been degraded.


The lake was created in the 1930s when the Sukkur Barrage was constructed on the river Indus. The lake is fed by two canals, the Aral and the Danister from the river Indus. Until recently the lake supported thousands of fisherfolk it is in near to village kot lashari bobak railway satation.who depended on the freshwater fish they caught in the lake. However, the lake is now undergoing environmental degradation resulting in the water becoming saline killing off the fish and forcing the fisherfolk to look elsewhere for employment.

Environmental Degradation:

The degradation has been occurring for a long time but only recently have the effects been felt. The diversion of water from the Indus and a diminished storm runoff from the Kirthar mountains have contributed to the reduction in fresh water supplies. At the same time, saline drainage water from agricultural fields in surrounding areas has started to flow into Lake Manchar. However between 16 august to 22 august 2009, 700 cusecs of water was introduced in the lake via Indus River.

The lake was a stop-off on the Indus flyway for Siberian migratory birds, but recently the numbers have fallen from 25,000 birds counted in 1988 to just 2800 bird counted in 2002, because the lake no longer provides the birds' main food, the lake fish. In the place of the birds, the lake now hosts a saline water reed.

The lake also provided large volumes of water for irrigation but this has also been reduced and has resulted in a great reduction in the area irrigated by the lake.


Nowadays, Lake Manchar is populated by the houseboat people of Mohana.
