Lagos Urges Calm After Floods, Approves Dredging

Lagos State authorities have called for calm after widespread flash flooding inundated numerous areas over the past two weeks. Governor Babajide Sanwo-Olu has ordered the immediate dredging of 28 additional primary drainage channels across the state.

“

the rains were an extreme weather event that produced an unusually high volume of water within a short period.

Commissioner for Environment and Water Resources, Mr. Tokunbo Wahab, described the recent heavy rains as an extreme weather event that overwhelmed existing drainage systems. He noted that areas like Victoria Island, Lekki, Ikeja, and Gbagada experienced temporary flooding due to the unusually high volume of water.

“

Lagos presented a much more complex hydrological system due to its extensive network of lagoons, tidal water bodies, rivers and creeks, as well as significantly higher rainfall intensity.

Wahab explained that the flooding was not unique to Lagos, with similar events occurring in other African and North American cities on the same day. He highlighted Lagos's complex hydrological system, characterized by lagoons, tidal bodies, rivers, and creeks, which naturally slows stormwater discharge into the sea, especially during high tides. This interaction, combined with intense rainfall, leads to inundation in low-lying areas.

“

the interaction between the Atlantic Ocean, Lagos Lagoon, and numerous rivers and creeks, particularly during periods of high tide, naturally slowed the discharge of storm water into the sea, resulting in temporary inundation in some low-lying areas whenever exceptionally heavy rainfall occurred.

The commissioner assured residents that the state government is actively monitoring drainage infrastructure and flood-prone locations. Emergency response teams are on the ground to manage receding floodwaters and provide support. Wahab also stressed the importance of resident participation in flood control efforts, alongside the government's significant investments in drainage construction and maintenance.

the Lagos State government was fully on top of the situation through continuous monitoring of drainage infrastructure, flood-prone locations, and other critical water channels.
