Iran’s Lake Urmia once boasted flocks of flamingos and swarms of tourists eager to swim in salty waters that covered an area more than twice the size of Luxembourg. Today, it more closely resembles a desert, littered with rusted cruise ships and beached docks (above). According to a 2014 report by an international consortium of scientists, Urmia has shrunk by a staggering 88 percent since the 1970s.

Droughts are partly to blame, but the primary culprits are dams and irrigation projects that divert the lake’s water sources. President Hassan Rouhani’s government pledged $5 billion for conservation efforts in 2014, but Iranian photographer Solmaz Daryani, whose family lives near Urmia, worries that may be too little, too late. Her photography of the desiccated landscape aims “to investigate the impact on [people] around the lake” and document what she describes as one of Iran’s “most unfortunate environmental disasters.”

A pumping machine, formerly used to disperse deep lake water to shallower coastal areas, sits abandoned in May 2015. The same month, an Iranian woman walks in front of a rusted boat while visiting the region with her family.

Local women observe deserted buildings in the village of Sheikh Wali in June 2015. The lake’s dehydration has hurt tourism and forced many locals to move away.

A family on holiday visits the receding shoreline in July 2015. As a child, Daryani remembers “the beachside inns and guesthouses were often full. But there are no guesthouses left.” Two local women float in Lake Urmia in August 2015. People have long bathed there for the water’s supposed remedial effects: The lake’s saline and black mud are said to treat skin conditions.

A family of tourists walks from Lake Urmia’s old coastline across a kilometer of dried earth to reach the remaining water in July 2015.

A man gathers salt from the parched earth to sell to local businesses in July 2015. The same month, employees of the government’s Urmia Lake Restoration Program arrive to supervise a tree planting project.
