Miqan Wetland is a wetland located in Markazi province, Iran. In years with good rainfall, the wetland has significant water level and in the years with less rain, the surface of the wetland generally dries and becomes a desert. The height of the wetland is 1,700 meters (5,600 ft) above sea level and the water inside of it varies in different seasons. Miqan is supplied from different water sources such as rainfall, water of three rivers known as Qarah Kahriz (Koohrood) River, Farahan River, Shahrab River, and Arak's wastewater treatment sewage. The area of the wetland is about 25,000 hectares (97 sq mi), which includes a lake with three islands in the middle and the surrounding plains. Archaeologically, the wetland's formation dates back to the Paleocene, which was due to the movement of the surrounding tectonic plates of the earth.
