Relocate Now Or Face Heavy Flood – Ogun Warns Residents

The Ogun State Government has issued a flood alert, advising residents of riverine and coastal communities throughout the state to evacuate to safer areas between the last week of September and the second week of October in order to mitigate the risks associated with severe flooding events.

Areas particularly vulnerable include communities along the Ogun, Ilo, Iju, Owa, and Yemule Rivers, specifically Isheri, Warewa, Akute, segments of Abeokuta, Ayetoro, Itele, and Iju, as well as coastal regions such as Makun, Oni, Iwopin, Igele, Ifaara in Ogun Waterside, Ebute-Imobi in Ijebu East, Tungeji Island, and Agosasa in Ipokia Local Government Area.

This advisory was articulated in the 2025 Ogun State Midterm Flood Alert Press Statement, which was disseminated on Sunday by the Commissioner for Environment, Dr. Ola Oresanya.

Dr. Oresanya indicated that the anticipated flooding is attributable to multiple factors, including river overflow, rising sea levels, tidal locking, intense precipitation, water inflows from the northern regions of Nigeria and the Benin Republic, as well as potential water releases from the Oyan Dam.

“The overflow, which usually lasts for two weeks, is part of the second phase of flooding that occurs every year between September and November,” Oresanya said.

Citing projections from the Nigerian Meteorological Agency, Oresanya disclosed that September will witness the highest rainfall with 204mm, followed by October with 190mm, before a decline to 93mm in November.

To mitigate the impact, he assured residents that the State Emergency Management Agency is on red alert for emergency evacuation and relocation to temporary camps. He added that the Ministry of Environment is working closely with the Ogun-Osun River Basin Development Authority to manage water releases from Oyan Dam.

The commissioner also cautioned residents in flood-prone areas against using boreholes and wells during this period, warning that water sources are likely to be contaminated.

Fish farmers across the state were advised to urgently harvest their stock to prevent losses, particularly those farming along floodplains in Eriwe, Yemule (Ijebu-Ode), Ilase, and Ayegbami in Yewa.

“Fish farmers must not delay in harvesting to avert their investments being washed away. Likewise, residents should avoid consumption of contaminated water as tidal variations will worsen water quality,” he warned.

Oresanya thanked residents for cooperating with the government on environmental issues, noting that such cooperation in the past six years had helped reduce flooding and its impact statewide.

He pledged the government’s continued commitment to safeguarding lives and property.
