Lagos Orders Emergency Dredging After Heavy Rain Triggers Widespread Flooding

Governor Babajide Sanwo-Olu has approved the immediate dredging and maintenance of 28 additional primary drainage channels across Lagos State following widespread flooding caused by recent heavy rainfall.

The Lagos State Government said the flooding was triggered by an extreme weather event that overwhelmed existing drainage infrastructure in several parts of the state.

Commissioner for the Environment and Water Resources, Tokunbo Wahab, disclosed this in a statement issued by the ministry’s spokesperson, Kunle Adeshina.

According to Wahab, the torrential rainfall led to temporary flooding in several communities, including Victoria Island, Lekki, Ikeja, Gbagada, Mushin and Mafoluku.

He stressed that the flooding was not unique to Lagos, noting that similar heavy rainfall affected other African countries and parts of North America on the same day.

The commissioner explained that Lagos faces a unique hydrological challenge due to its extensive network of lagoons, rivers, creeks and tidal water bodies.

He said the interaction between the Atlantic Ocean, Lagos Lagoon and other inland water bodies, particularly during periods of high tide, naturally slows the discharge of stormwater into the sea, leading to temporary flooding in low-lying areas after intense rainfall.

“The Lagos State Government on Tuesday called for calm and understanding from residents following the massive flash flooding experienced in many parts of the state over the last two weeks, with Governor Babajide Sanwo-Olu approving the immediate dredging and maintenance of 28 additional primary channels across the state,” the statement read.

It added that the state government remained fully in control of the situation through continuous monitoring of drainage infrastructure, flood-prone communities and other critical water channels.

Meanwhile, urban planner and environmentalist Michael Simire attributed the recurring floods in Lagos to multiple factors, including high rainfall intensity, poor drainage systems, blocked canals and drainage channels, the city’s low-lying coastal terrain, weak enforcement of building setbacks, and the encroachment of structures on waterways, which significantly reduce the capacity of drainage networks.
