Several fresh-water rivers flowing upstream Iran have been shrinking, leaving agriculture, ecology, lives and many livelihoods at stake.
Hamoun, inthe countrys southeast, is the most serious example which has run dry in the wake of a massive dam built with American funding in Afghanistan.
As a result, the majestic wetlands have become parched, affecting more than 2 million residents in Irans Sistan-Baluchestan province where many villages and towns have entirely been banished.
In the south, Arvand River formed by the conflux of the Tigris and Euphrates downstream Iraq is menacingly becoming depleted.
The Tigris has its source in Taurus mountains in Turkey, which has been chocking the flow through excessive damming, diversion and exploitation. The Euphrates, also originating in Turkey and crossing Syria, faces similar fate.
Another Iranian river coming down from Turkey is Aras which drains tributaries in Armenia and Azerbaijan before trickling into Iran in declining volumes in recent years.
Iranian media have also accused neighboring Turkmenistan of excessive pumping of deep-well waters in the countrys east and leaving many Iranian border villages scorched.
Experts believe the problem is on course to deteriorate in the absence of basin agreements among the countries on allocation and management of cross-border fresh water resources.
President Hassan Rouhani has cited water as a national security issue. Last month, Energy Minister Hamid Chitchian warned of possible water supply cuts and rationing in the summer, calling on the public to slash consumption.
The only condition which will enable us to avoid a cut is for the people to control and limit their consumption and help the Energy Ministry save water, the minister said in a blunt warning.
According to deputy Interior Minister Esmaeil Najjar, more than 500 Iranian cities are struggling with drinking water shortage.
