In a recent announcement, the Nigeria Hydrological Services Agency (NiHSA) has sounded the alarm regarding dangerously high water levels in both the River Niger and River Benue. The agency, through a release signed by Director-General Umar Ibrahim Mohammed on Thursday, cautioned that these rivers and several of their tributaries are now at their seasonal peaks. The immediate implication: heightened flood threats loom over communities residing along the riverbanks, especially as the rainy season retains its full momentum across West Africa.
According to NiHSA’s latest advisory, tributaries such as Rima, Kaduna, and Gongola are also displaying critical water levels. The rainy season’s persistent downpours have significantly increased the inflow into these water bodies, exacerbating pressure on major dams nationwide. As a result, several key dams are being forced to spill excess water to maintain structural safety, a measure that unfortunately raises the likelihood of downstream flooding. Kainji and Jebba dams on the River Niger have become focal points of concern, with both currently releasing large volumes of water, leaving downstream areas in Niger, Kwara, and Kogi states—such as Kainji town, Patigi, New Bussa, Borgu, Mokwa, Jebba, Gungu, Gana, Fanga, Bele, Bere, Gaba, and Baro—on heightened alert.
Local officials and community leaders in these regions are reportedly bracing for difficult days ahead. “We are already observing increased water levels in farmlands and homes. People are worried, especially after witnessing the damages from previous floods,” remarked Mrs. Charity Sanni, a resident of Mokwa. Her story echoes a growing sentiment among riverine Nigerians, for whom seasonal flooding often brings both immediate dangers and longer-term economic challenges, particularly to agriculture and transportation.
The Goronyo Dam in Sokoto State is also making headlines. Having now reached its maximum designed reservoir level of 288 meters, the dam is currently spilling at its full capacity. This has resulted in ongoing flooding incidents in places like Goronyo, Wamako, Shinaka Yerimawa, Kurukuru, and surrounding communities. Local authorities are urging residents to move to higher ground where feasible. Meanwhile, the Kiri Dam on the River Gongola in Adamawa State is overflowing as well, with downstream repercussions in Kiri, Tallum, Banjiram, Purokayo-Lakumna, Shelleng, and their environs.
Though Zungeru Dam—another significant piece of Nigeria’s hydrological infrastructure—is not currently spilling water, NiHSA notes its reservoir levels remain troublingly high. Across the border in Cameroon, there are growing concerns over the status of the Lagdo Dam on the Benue River. The agency’s report states that, as of the time of writing, Lagdo Dam has not released water, yet its water level has climbed to roughly 37 meters—just shy of its maximal design specification of 40 meters. Although not immediately at risk of spilling, any sudden discharge could worsen flooding further downstream in Nigeria.
Heavy rainfall remains the main culprit behind the recurring flood events in many Nigerian communities. NiHSA attributes the recent flooding in Adamawa—especially in Yola North, Yola South, Girei, and Numan—to intense local rains and natural runoff within the Benue catchment. These patterns are not isolated. Experts say this mirrors a larger trend across the West African region, where seasonal rainfall is on the rise, in part due to shifting climate conditions. Dr. Bassey Oko, a hydrologist based in Lagos, explains, “Nigeria’s river systems, particularly Niger and Benue, are highly sensitive to both weather fluctuations and dam management policies. Effective coordination, both domestically and with neighboring countries like Cameroon, is critical to mitigating disaster risks.”
Communities along the rivers have learned to adapt, yet increased flooding puts additional pressure on local government resources and humanitarian agencies. Floodwaters not only threaten homes and infrastructure but also disrupt farming cycles, damage roads, and heighten the risk of waterborne diseases. According to past reports from Nigeria’s National Emergency Management Agency (NEMA), the country experienced devastating floods in 2012, affecting over 7 million people and displacing hundreds of thousands. More recent years have brought similar, though sometimes less reported, challenges, with 2022 seeing mass evacuations and significant loss of crops in several floodplain states.
NiHSA’s warnings come as authorities across Nigeria race to implement mitigation measures. Emergency teams have been placed on standby in susceptible states, and sensitization campaigns urging residents to relocate from high-risk floodplains have intensified. However, limited funding and the ongoing challenge of persuading community members to abandon their ancestral lands—where livelihoods and cultural ties run deep—mean the task ahead remains daunting.
The Ministry of Humanitarian Affairs and Disaster Management has also stepped in, coordinating with state governments to provide temporary shelters and relief materials where flooding has already begun. “Mitigation and preparedness are collective responsibilities,” says a spokesperson from the ministry. “We encourage everyone to heed official advice and report early signs of flooding to local authorities to prevent loss of lives and property.”
Outside Nigeria, developments surrounding dam management on international rivers like the Benue underscore the importance of close cooperation between neighboring countries. Previous episodes, including the 2012 Lagdo Dam release from Cameroon, resulted in severe flooding downstream in Nigeria, prompting fresh calls for improved regional water management treaties. Authorities have also explored options such as establishing a Nigerian dam downstream of Lagdo to act as a buffer, a project which has faced delays.
With hydrological data indicating that flood risk will persist as this year’s rains continue, experts are calling for stronger investment in early-warning infrastructure, better coordination between government levels, and renewed commitment to sustainable environmental practices. These could include improved urban drainage, more rigorous enforcement of building codes, and expanded community education programs. According to the World Bank, effective flood risk management could save Nigeria billions of naira in property and crop loss every year.
For Nigerians living in flood-prone zones, vigilance will be key over the coming weeks. NiHSA has reiterated its advice for residents along the Niger and Benue riverbanks to implement proactive safety measures—such as moving valuables to higher ground, avoiding risky travel during heavy rainfall, and staying updated with official announcements. Across the country, the interplay between climate, infrastructural resilience, and community action remains at the heart of Nigeria’s ongoing struggle to control the annual threat of riverine flooding.
As other nations in West Africa, including Ghana and Cameroon, face similar hydrological challenges, these developments also present an opportunity for regional learning and stronger transnational collaboration. Reliable, locally tailored solutions remain crucial for protecting both people and economies as the impacts of climate variability grow more pronounced on the continent.
