Rawal Dam was built across the Korang Nallah, 9 miles from Rawalpindi, between 1960 and 1962. It is a concrete dam 700 feet long, 100 feet above the river bed. It has a storage capacity of 47,500 acre feet and covers 3.5 square miles. Along the right side is an outlet for 112 cusecs of water supply, 32 cusecs (16.5 million gallons per day) for urban water supply and the rest for irrigation.
In recent years, the supply of water for irrigation has been curtailed due to an increased demand for urban drinking water.
People of Rawalpindi mainly depend on water supply from Rawal Dam. This Dam is situated in Islamabad and is one of the beautiful dams of Pakitan. Administratively, it comes under control of Rawalpindi government. It is also a source of fresh water fish.
In second half of June, the people enjoying the strolling along the bank of Dam noticed many dead fish .It was reported to relevant authorities. These dead fish have been sent to the government laboratory for chemical and biological examination.
The common question of debate among people of Rawalpindi now a days is, "Is water from Rawal Dam safe and suitable for drinking purposes?"
