Gahar Lake is located in the highlands of Iran, in the southeast of Dorud,[1] in Lorestan province protected zone at an elevation of 2,400 meters.
[2][3] The lake is known as the jewel of Oshtarankooh and due to the lack of roads and lower use of cars and automobiles, it is basically free from being damaged and polluted by humans.
The reason for the increase in the volume of water leaving the lake is the presence of springs in its lower part.
Vegetation The vegetation of this region includes trees and plants such as oak, willow, almond, terebinth (wild pistachio), European pear, plane trees, elm, quercus infectoria, walnut, fig, European ash, apple, hawthorn, prunus dulcis, Gahar’s ziziphus spina-christi, pomegranate, gaz, and vinifera (wild grapes).
The first and oldest documentary image of the lake was taken in 1891, belonging to a French tourist named Jean-Jacques Dumergané.
