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, near village Kot Lashari Bobak railway station,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 and killing off the fish and forcing the fisherfolk to look elsewhere for employment.
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 2,800 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.
