Lake Hamun biosphere reserve and its Lagoon in Iran are together recognized by UNESCO. It is the third-largest body of water after the Caspian Sea and Lake Urmia in Iran and the seventh-largest lake in the world. Lake Hamun (also spelled Hamoun or Hamoon) is made up of three smaller lakes called Hamun-e Puzak, Hamun-e Saberi and Hamun-e Hirmand. When these lakes rise, they form a single lake called Hamun. This lake is located in Sistan and Baluchestan Province. Hirmand River is the main source of water emptying into it.

The name of Lake Hamun is cited in Avesta, the primary collection of religious scriptures of Zoroastrianism. Old Iranian books written in the Pahlavi and Persian languages have mentioned the name of Hamun several times. Some believe that thee settlements around Lake Hamun used to be the center of Zoroastrianism in the past. In ancient times, this lake was a sacred place for Iranians.

Geographical Location of Lake Hamun

This lake used to cover an area of 5,660 km2. Half of this lake is located in Kerman Province and the other half is in Sistan and Baluchistan Province. Jiroft, Faryab, and Rudbar plains are in Kerman province near Lake Hamun. Iranshahr, Bampour, Sardgan, Dalgan, Sartakhti and Espakeh plains are also near Hamun in Sistan and Baluchestan Province.

There is tropical vegetation growing up along the lake. The mountainous region forms 34,000 kilometers of the land around Hamun. Plains and foothills cover an area of 32,000 kilometers. Swamp has covered approximately 3,000 kilometers of Lake Hamun.

In the mountainous highlands of Lake Hamun, the precipitation reaches 600 mm sometimes. Hamun biosphere reserve and its surrounding area are classified as desert areas due to their elevation from sea level. The highest area of this reserve is Mount Shah, which is 4,400 meters above sea level. The lowest point around Hamun is the Jazmurian depression, which is 350 meters above sea level.

Hamun covers an area of 3,820 km2 of Iran and the rest is located in Afghanistan. Hamun is one of the natural monuments recognized as the UNESCO Biosphere Reserve. Hamun Lagoon is located in one of the warmest and driest climates in the world. Hamun Lagoon is linked to Helmand River at the Afghan-Iranian border. The region is the second in terms of the sandstorms in Asia.

Chah Nimeh is a water reservoir consisting of three basins or three natural depression along Helmand River. The creation of the basins dates back to the Quaternary geologic period. The Chah Nimehs in Sistan area is an important factor for the survival and residence of the people in this area.

The maximum depth of this Lake Hamun is about 11 meters. Mount Khajeh, with a height of approximately 609 meters above sea level, is the only natural phenomena of Sistan Plain. This mountain looks like a small island between Hamun and Hirmand during the high water. The lowest points of the area are located in the southern and northern parts of Hamun with a height of 467 m above sea level.

The amount of water entering upstream of the Helmand River is very high, but before it reaches Iran, it is severely depleted due to the high consumption of Afghans.

Life around Hamoon Biosphere Reserve

The importance of this region is mainly due to its habitat for wildlife, the possibility of fish farming, the availability of different bird species and the provision of livestock feed from reed beds and the use of reeds for caning. Lake Hamun is a permanent habitat for some creatures, while for some others is a temporary habitat for transiting and feeding. Halil River and Bumpur River flow into Lake Hamun.

Located in the center of the desert region, Hamun Protected Area is the only habitat for migratory birds. The freshwater lakes, swampy lands, and the water distribution due to river flood have made the region host hundreds of thousands of migratory birds.
