The Benue confluence — day two of a published ramp

BUILDING · September 18, 2026 · NO. 0918

THE WATER

The one flood on this board with a clock on it, and the clock is now running. The regulated Lagdo release — ramping 100 to 1000 m³/s over seven days from Sep 17 — is on its scheduled day-2 ramp, with the national emergency operations centre active and eleven Benue-bordering states on alert. Carried per the hydrological service's schedule rather than independently confirmed underway, and kept distinct from the rain-driven flooding already on the same rivers.

CONNECTED

One flood published its start time a week ago and the other has changed address three times in four days — Nigeria's release is on its scheduled second day, ramping toward 1000 m3/s across seven, which is lead time an agency can sequence evacuations against.
