The Lagos State Government has appealed for calm following persistent rainfall and flash floods across many parts of the state over the past two weeks, and has announced the immediate dredging of 28 additional primary drainage channels to improve flood control.

Governor Babajide Sanwo-Olu approved the emergency dredging intervention as part of efforts to strengthen the state’s drainage network.

Commissioner for the Environment and Water Resources, Tokunbo Wahab, said the recent downpours were an extreme weather event that produced an unusually large volume of rainfall within a short period, overwhelming drainage systems in some locations and causing temporary flooding in parts of Victoria Island, Lekki, Ikeja, Gbagada, Mushin, Mafoloku and other communities.

According to him, the situation was not peculiar to Lagos; several African countries and parts of North America also experienced heavy rainfall and flooding during the same period.

Wahab, however, said Lagos presents a more complex hydrological challenge because of its extensive network of lagoons, rivers, creeks and tidal water bodies, coupled with its high rainfall intensity.

He explained that the interaction between the Atlantic Ocean, Lagos Lagoon and inland waterways, especially during high tide, naturally slows the discharge of stormwater into the sea, leading to temporary flooding in low-lying areas during exceptionally heavy rainfall.

The commissioner assured residents that the government was closely monitoring drainage infrastructure, flood-prone areas and major channels across the state.

He added that emergency response agencies had been deployed to affected areas to facilitate the quick recession of floodwaters and provide necessary support to residents.

Wahab said the government would continue to invest in drainage construction, channelisation, desilting, and other flood-control infrastructure, but stressed that residents also have a responsibility to support these efforts.

He urged residents to stop dumping refuse into drains, canals and waterways, warning that blocked drainage channels and illegal reclamation of wetlands contribute significantly to flooding.

He also cautioned against building on drainage alignments and engaging in activities that could obstruct the free flow of stormwater.

The commissioner said the increasing frequency of extreme rainfall events across coastal cities was a clear indication of the impact of climate change.

“Lagos is not exempt from these realities. However, the State Government remains steadfast in its commitment to building a flood-resilient city through sustained infrastructure development, environmental enforcement and active collaboration with residents,” he said.

Wahab described flood management as a shared responsibility, urging residents to keep drainage channels free of debris and to report any activities that could obstruct stormwater flow.

He also advised motorists to avoid driving through flooded roads during heavy rainfall and urged residents, particularly those in flood-prone communities, to comply with weather advisories and safety instructions issued by relevant government agencies.

He reaffirmed the government’s commitment to protecting lives and property through proactive flood management measures and called for continued public cooperation in building a cleaner, safer and more resilient Lagos. (The Nation)
