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.
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.
