The drying up of the "Siah Darvishan" river in Gilan; where does the crisis feed from?

In one of the rainiest provinces of the country, a river like Siyah-Darvishan has completely dried up. This incident, more than being a result of drought, is the outcome of excessive withdrawals, diversion of water resources, and weak management in allocating environmental water rights.While Gilan is still blessed with rainfall, its rivers are gradually drying up one by one; this is a serious warning for Anzali Wetland and the region's ecosystem.When in the land of rain, a river dries up, one must ask: Who is responsible?
