Nigeria — the scheduled release begins today, onto a river the rain already took

THE WATER

The regulated Lagdo release is scheduled to begin today, ramping 100 to 1000 m³/s over seven days onto the Benue confluence, with NEMA's Abuja emergency operations centre activated and eleven Benue-bordering states on alert. The flooding already on that ground is rain-driven — two mechanisms, one river, kept apart on this page for a sixth morning. Dam impounding about 209.82 m against 216 m.

CONNECTED

One flood published its start time a week ago and the other arrived with no number on it at all — Nigeria's release begins today and ramps 100 to 1000 m3/s across seven days, which is lead time an agency can sequence evacuations against.
