The statement read in part: “The River Niger Basin which covers nine countries of Benin, Burkina Faso, Cameroun, Chad, Cote D’Ivoire, Guinea, Mali, Niger and Nigeria, has Nigeria at the lowest portion of the Basin. This means that once the upper catchment of the Basin gets flooded, Nigeria should be prepared to experience flooding incident.

“As at today, the Middle Niger of the Niger Basin made up of Niger, Benin, Burkina Faso and part of Mali, have been flooded. The flood levels at the hydrological stations monitored in Niamey (Niger Republic) and Malanville (Benin Republic) have gotten to the Red Alert Zone.

“Latest information received by Nigeria Hydrological Services Agency (NIHSA) from the regional Niger Basin Authority (NBA) Hqtrs in Niamey had it that as at Sunday, 23rd August 2020, the flood level of River Niger monitored in Niamey was 6.60m.

“This is already within the Red Alert Zone. Flood Alerts as zoned by the NBA are as follows:
Yellow Alert: 5.50m – 5.80m;

“Accordingly, Kainji Dam is now spilling water at the rate of 1,000 m3/s, i.e. 86.4 million cubic metres/day. This means that communities downstream Kainji and Jebba Dams could be flooded.

“The Shiroro Dam on Kaduna River is still impounding, though there is the possibility of spilling water in the weeks ahead,” it added.

However, the agency said it had continued to monitor the developments on River Benue sub-basin and had maintained close contact with the Cameroonian authorities with regards to flood scenarios in the upper catchment of the sub-basin.
