Key highlights: In late May 2026, the Euphrates River experienced severe flooding, expanding to three times its normal size, from 60.9 km² to 188.7 km², following exceptional upstream rainfall and large‑scale dam water releases. The flood inundated 7,210 hectares of agricultural land, equivalent to 8.2% of all cultivated land in Deir‑ez‑Zor Governorate, at a critical time during the wheat harvest period. The most severely affected areas include the surroundings of Deir‑ez‑Zor city, Muhasan–Khasham, and Basira–Al Mayadin, with flooding observed along both banks of the river. The flooding poses significant humanitarian risks, including reduced food availability, disrupted livelihoods, potential infrastructure damage, WASH concerns, and possible temporary displacement of riverine communities. The findings provide strong evidence to support urgent response planning, geographic targeting, and coordination with partners, while field verification is required to confirm the full extent of impacts.
