The Lagos State Government has issued a warning to residents about the potential risk of flash flooding following significant rainfall described as the “heaviest in many months.” The alert was communicated by State Commissioner for the Environment and Water Resources, Tokunbo Wahab, over the weekend.
RISING Water Levels and Dam Releases
Wahab explained that the recent heavy rains, particularly between Wednesday and Thursday, have caused water levels in major rivers to rise. This situation has hampered the drainage channels’ ability to discharge water effectively, particularly due to the simultaneous release of water from the Oyan Dam.
“The intensity of the rainfalls has led to the levels of the major rivers rising, making it difficult for the drainage channels to discharge until levels gradually subside,” he said.
Recent Data and Flooding Concerns
The commissioner emphasized the necessity of the flash flood advisory based on data collected from weather monitoring stations, which indicated that Thursday’s rainfall was among the highest recorded this year. He highlighted the following observations:
- Rising Water Levels:
- At Kara, the water level reached 2.2 meters, nearing the flood threshold.
- At Isheri-North GRA, the water level was reported at 20.015 meters, above the flood threshold, indicating river flooding in nearby catchment areas.
- The peak water level at Majidun was recorded at 1.466 meters on October 14, with minimum levels at 0.538 meters.
- Falomo also reported increasing water levels due to continuous rainfall and releases from the Ogun-Osun River Basin Development Authority (OORBDA).
Safety Precautions for Residents
Wahab urged residents, particularly those living in low-lying areas and along the banks of the Ogun River, to prioritize their safety. He recommended moving to upland areas to prevent potential loss of life and property, especially since more rainfall is expected in the coming weeks.
“The data available for October shows significantly higher water levels compared to previous months. Continuous monitoring indicates that residents should prepare for possible flooding conditions,” he reiterated.
Residents are advised to stay informed and take necessary precautions as the state navigates the challenges posed by heavy rainfall and rising water levels.
