Nigerian hydrological agency (NIHSA) warns that Friday’s floods in many parts of Lagos are likely to be far less severe than those that will be experienced in September.

According to NIHSA’s Annual Flood Outlooks for 2021, the year will have more flood cases than any other year since 2012. This report was made public during the 2021 Annual Flood Outlook in Abuja in May 2021.

In the wake of Friday’s flooding, the NIHSA asked Lagos residents to prepare for severe flooding in September, the rainy season’s peak, by taking all measures necessary now to mitigate the devastating effect.

Lagos’ peak rainy season is forecast for September, and it has always been there. Therefore, what happened across the state on Friday may not be as intense as what will happen during the peak of the rain, Clement Nze, NIHSA’s Director-General, told Punch.

Additionally, the agency reported that no new holding dams had been constructed across the River Niger in Nigeria or on the course of the Ladgo Dam in Cameroon to mitigate the effects of flooding resulting from the possible opening of the dam.

Nigeria was advised by Cameroon to construct holding dams in the River Niger and Ladgo Dam to prevent damage from the released water, as was seen in 2014 and 2016.

According to Nze, experts are designing a dam for this purpose ahead of the actual budget preparation.

Additionally, Nze explained that if the water level in the Oyan Dam in Abeokuta rose, the dam might need to be opened in order to release the water and avoid rupturing.

The flooding in the South-West states might worsen once the Oyan Dam is opened to release water.

The flood situation in that region will be worse if the Oyan Dam collapses. Therefore, it is better to let some of the water from the dam out once its level gets high enough to do so, he said.

NIHSA’s boss also talked about the agency’s flood predictions.

According to him, Lagos and its surrounding areas were included in our predictions for flooding that occurred. Also, Lagos is one of the 10 megacities globally, meaning it might sink or disappear in 50 years based on meteorology.

After reading one of my posts in 2019, one of my cousins sent me a voice message, telling me they told her in Germany that Lagos State would sink in the next 50 years.”
