Some of the lakes, such as Namal lake (480 ha), Uchhali lake (943 ha), Jahlar lake (100 ha), Kallar Kahar (100 ha), Kharal lake (235 ha) and Khabikki lake (283 ha) are brackish and are too saline to support aquaculture. Other man made lakes include Mangla dam, Terbela dam and Chashma Barrage. Aquaculture (or fish farming) is new in Pakistan. However, there is immense potential for development of the sector.
