About 10 kilometers south of Poldakhtar city and in the green village of Valiasr, there is a set of small and large lagoons, which is the habitat of many animal species.
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.
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.
Shahre-chai Dam is one of these lakes which has become one of the important tourist destinations of the province due to its beauty and proximity to big cities such as Urmia.
