Originally Haleji Lake was a very small lake. During World War II the then British Government of Sind decided to increase the capacity of this lake by having a feeder canal from River Sindh. This lake supplies water to Karachi. During War time thousands of American and British Troops were stationed in Karachi. The lake work was taken on War Footing and was completed within 24 months.
Haleji Lake is 85kms form Karachi.
