NIGERIA — A 15-STATE FLOOD ADVISORY TO SEP 25, RAIN-DRIVEN, WITH NO DAM RELEASE

On the board · September 22, 2026 →

THE WATER

The national advisory for Sep 19 to 25 carries high riverine and flash flooding across 15 named states, with more than 8,000 communities and 4,500 schools flagged, Lagos ordering evacuation of low-lying areas, and nine river gauges under watch. The mechanism matters and is unchanged: the flooding is rain-driven, and the Lagdo Dam upstream is impounding, not releasing — the release narrative stays debunked. The widely quoted 209.82 m of 216 m reservoir level is an Aug-30 vintage the September advisory does not restate as a live trigger, so it is dated here rather than repeated as today's. Watch the rainfall and the gauges, not the dam headline.
