Tucked in the southern periphery of the Salt Range and hemmed in by its higher cliffs, is a cluster of natural lakes — Ucchali, Khabbeki and Jhallar in district Khushab. These lakes are said to be 400 years old, maybe more. The lakes are a prime sanctuary for the migratory birds and were declared a protected sanctuary for the native and migratory avifauna on the appeal of World Wildlife Fund. Nestled at about 800 meters above the sea, lakes have some marsh vegetation and are mostly surrounded by cultivated land, which is picturesquely intersected by hillocks. The lakes are fed by the spring, seepage from adjacent areas, and run off from the neighbouring hills of the historic Salt Range. The lakes are one of the most important wintering areas for the rare white-headed ducks (Oxyura leucocephala) in Pakistan that comes here from Central Asia. Locals believe that there is a volcano hidden beneath the surface of the Ucchali Lake due to which the colour of the water keeps changing. The appearance of a vert broad and brightly coloured rainbow in 1982 for consecutive 15 days is also attributed to this analogy. in 1982, a strange phenomenon was observed in the villages Ucchali and Dhadhar. The lakes’ water is also said to cure gout and skin diseases. People have been taking the water from the lakes as far as Lahore and Karachi. People think that a pure white winged creature called Great egret, from Grus family, found in the area is a symbol of longevity.
