Rainfall increases Lake Urmia level

February 25, 2020 - 18:1

TEHRAN – Recent rainfall has increased the level of Lake Urmia to 1,271 meters, a step closer to its ecological level of 1,274 meters.

Shared between West Azarbaijan and East Azarbaijan provinces in northwestern Iran, Lake Urmia was once the largest salt-water lake in the Middle East. 

However, decades of long-standing drought spells and elevated hot summer temperatures that speed up evaporation as well as increased water demands in the agriculture sector shrank the lake drastically. In 1999 the volume of water which was at 30 billion cubic meters drastically decreased to half a billion cubic meters in 2013. Moreover, the lake’s surface area of 5,000 square kilometers in 1997 shrunk to one-tenth of that to 500 square kilometers in 2013.

The lake is expected to reach its ecological level within 10 years by completing the restoration plans which started four years ago.

Farhad Sarkhosh, head of the Lake Urmia Restoration Program’s office in West Azarbaijan province, said that the Lake’s level is now 58 cm higher than it was last year. 

According to the latest monitoring, the lake's water volume is estimated at more than 3.6 billion cubic meters.

He added that the lake surface area has reached 2,883 square kilometers, adding that the figure is increased by 538 square kilometers compared to the same period last year.

Although the ecological level of the lake is defined as 1,274 meters, the lake will also have favorable conditions at 1,272 meters and more than 90 percent of sand and dust storm hotspots will be eliminated.

Alireza Shari’at, head of monitoring and supervision department of the Lake Urmia restoration program said in September 2018, that in order to maintain the Lake Urmia ecological balance of 14 billion cubic meters over the next 10 years, an annual amount of 3.3 billion cubic meters of water is required.

The sharp rise in precipitations rates over the past crop year since now has raised hopes for total restoration of the once glorious Lake Urmia.

This is a while, deputy environment chief Masoud Tajrishi told Khabaronline in July 2019 that rainfall is not the only the reason behind Lake Urmia coming back to life. Thus, restoration measures turned out to be effective, unlike the previous years of high rainfall poured over the lake but did not raise the lake level.

The effort put into properly dredging and clearing of weed and vegetation in river beds as a way came efficient in the lake conservation, he added.
