Syrian authorities have declared the worst phase of a major Euphrates River flood over, after Turkish dams upstream released unprecedented volumes of water into Syrian territory without prior coordination with Damascus. The head of the emergency response committee in Deir ez-Zor province — a city in eastern Syria that sits along the Euphrates near the Iraqi border — said the region had passed the most dangerous stage of the crisis and expected conditions to return to full stability within 48 hours.
The flooding was triggered by a combination of heavy seasonal rainfall and the opening of spillway gates at Turkey's Karakaya and Atatürk dams, two of the country's largest hydroelectric facilities on the Euphrates. The releases sent flows exceeding 2,000 cubic metres per second into Syrian territory — levels not recorded in decades — and the Atatürk dam gates were opened for the first time in seven years. Syria's Energy Minister stated publicly that Turkey acted without advance coordination with Damascus, causing a sudden and significant surge that put riverside villages at risk. Turkish regional water authorities, for their part, described the releases as a controlled operation made necessary by exceptionally heavy rainfall that had raised reservoir levels in recent months.
On the Syrian side, dam operators acted swiftly to manage the downstream impact. The administration of the Euphrates Dam inside Syria closed a second spillway opening within three days, producing a measurable drop in river levels. Satellite imagery analysed during the crisis showed the river's dramatic lateral spread across both banks at the flood's peak, and the closure of the gates has begun to reverse that spread, with water receding from large areas of farmland and homes.
The human and material toll, while significant, was contained. No flood-related deaths were reported, with authorities noting that any casualties were linked to routine annual swimming incidents rather than the flood itself. More than 10,000 dunams of agricultural land were damaged, and a committee has been formed to assess losses and compensate affected farmers. Some bridges were put out of service, and 62 water pumping stations were proactively shut down and their equipment dismantled before floodwaters could submerge them. Five stations have since been reactivated and 56 others reinforced. Hospitals in several eastern towns were supported with additional resources, including the transfer of dialysis machines to facilities in the affected area.
The episode has reignited longstanding concerns about water-sharing arrangements along the Euphrates, a river that flows from Turkey through Syria into Iraq and is vital to agriculture and drinking water across the region. Syria's transitional government had issued early warnings last week urging residents to stay clear of the riverbank after projecting a rise of more than two metres. The absence of prior notification from Turkey, however, left communities with limited time to prepare, underlining the fragility of transboundary water management in a basin that has long been a source of geopolitical tension.
