Yola, Adamawa state - The federal government of Nigeria has issued an alert to residents in 11 states regarding the imminent release of water from the Lagdo Dam in Cameroon.

As reported by Africa Independent Television (AIT), the alert was disclosed during a recent simulation by the National Emergency Management Agency (NEMA).

TVC News also noted on Sunday, August 23, that NEMA conducted the flood simulation exercise in Adamawa state to strengthen preparedness and response to potential flooding. The exercise is designed to test emergency response systems, improve coordination among relevant agencies, and enhance the capacity of communities and responders to manage flood-related emergencies.

According to reports, authorities of the Lagdo Dam will commence controlled water releases soon.

The initial discharge rate could be 100 cubic meters per second (m³/s), equivalent to 8,640,000 cubic meters per day.

This rate is expected to progressively escalate to 1000 m³/s for days, depending on the inflow from the upstream Garoua River, which is the primary source feeding the reservoir and a significant tributary to the Benue River.

NEMA director-general Zubaida Umar, who was represented at the simulation exercise in Adamawa by the director of search and rescue, Air Commodore B. A. Usman, said it was commendable that Nigeria no longer waits for disasters to occur before taking preventive measures.

The NEMA official added:

"Where it (flood disaster) happens, we reduce it to the barest minimum."

Cameroon plans gradual water discharge

NEMA officials further emphasised that the planned water discharges would be gradual.

The overflow from the Lagdo Dam is expected to cease once there is a noticeable reduction in the flow into the reservoir.
