Daryuk or Deyuk Lagoon is the name of one of the Kelardasht reservoirs, which is attractive to many tourists and nature lovers due to its unusual appearance.
This lake is located on a roaring river and the existence of very beautiful mountains along the lake, which are green and very depressing from mid-April to September, has created a unique view.
Before entering Khuzestan province, Karun river is known as Bazoft. Shortly before the Karun 4 dam, the Khersan river crosses the Bazoft river to form the massive Karun river.
To control the seasonal floods of the Kor River and store its water, a dam called Mulla Sadra has been built on it. This dam is located about 175 km north of Shiraz and near the city of Sedeh.
