Ogun State Government has warned residents of adjoining communities in the State to relocate to safer environment between the last week of September and the second week of October 2025  because of the expected impact of  rain overflow from the following Rivers and tidal lock;  Ilo, Iju, Owa, Yemule, while,  rivers, such as Isheri, Warewa, Akute, Ayetoro, Itele, Iju and those of the coastline of Makun, Oni, Iwopin, Igele, Ifaara (Ogun Waterside), Ebute-Imobi (Ijebu East), Tungeji Island and Agosasa in Ipokia Local Government are expected to rise also.

           Commissioner for Environment, Dr. Ola Oresanya gave the warning at the 2025 Ogun State Midterm Flood Alert, saying, residents should be prepared for the second phase of flooding which would last for 2 weeks, predictably, from September through November yearly.

 He noted that  communities mentioned were prone to  expected high rainfall and arrival of flow from the northern part of the country and its neigbour such  Benin republic to Ogun and Lagos States on the downstream, adding that, the release of water from the  Oyan Dam might compound that of Ogun State.

           Oresanya revealed that the Nigeria  Meteorological Agency NIMET, had predicted that September would have the highest rainfall of 204mm, followed by October at 190mm, while by November the intensity of the rainfall wound have gone down to 93mm.

           He therefore assured the residents of these communities that the State government through its State Emergency Management Agency (SEMA) is on red alert in case of any emergency evacuation and relocation to temporary emergency camps spread across the State, while the Ministry of Environment is also working closely with the Ogun - Osun River Basin Development Authority on the release of water from Oyan Dam to reduce its impact to the barest minimum.

           Oresanya also urged residents in these communities to avoid the usage of boreholes and Well water at this period as they are subject to contamination due to the expected flooding and tidal variations.

           He equally used the opportunity to call on fish farmers farming on flood plains of rivers and streams statewide to harvest their fishes to avert them being washed away by flood while fish farmers at Eriwe, Yemule, both in Ijebu ode, Ilase and Ayegbami in Yewa are equally advised to heed the advice without further delay.

           While thanking residents of the state for their understanding on all environmental issues, especially on its yearly flood alert, he lauded them for their cooperation with the State government in the last six years which had reduced flooding and its impact greatly statewide, while pledging the State government commitment to continually do the needful to make the State flood free.
