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.

The area of the wetland is about 25,000 hectares (97 sq mi),[2] 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.

[3] The Miqan Wetland has special ecological features, including the fact that it hosts a large number of migratory birds each year, among which some rare and protected species can be seen.

In addition to birds, mammal species, artemia (brine shrimps), and saltwater algae are other living things in the wetland and its surroundings.

The nearest mountain to the wetland is located 10 kilometres (6.2 mi) southeast of it, which is called "Kooh Takht Zard" with the height of 2,269 meters (7,444 ft).

In the recent years, the entry of sewage effluent in the city of Arak at the rate of 700 litres per second (25 cu ft/s) has been another source of water supply in the wetland, which has affected the region's ecosystem.

[12] Miqan Wetland is a vulnerable environment because of its size, ecological features, and the extent of its impact on the climate of the region and the city of Arak.

Due to the evaporation and transpiration of these plants, their stability decreases in the summer season and the species go down to obtain water for their roots and cover the hill in the form of an umbrella.

[15] Every year, 25 to 30 thousand migratory birds of various species, including gray terns, travel to Miqan Wetland to spend the winter.

[20] In addition to the mentioned species, some wild animals such as wolves, foxes, snakes and all kinds of lizards also live in the areas around the wetland.

This issue will cause the soil of the lagoon to loosen, which in the long process can endanger the lives of the residents of Arak city.
