Nairobi, April 30, 2026 — The government has warned of rising flood risks across the country as heavy rains continue to push water levels up in key dams along the Tana River cascade.
In a statement, Government Spokesperson Isaac Mwaura said the situation remains serious, with several incidents already reported and more risks expected in the coming days.
Tragedy struck in Roysambu, Zimmerman area, on the night of April 28 when a 29-year-old woman was swept away by fast-moving rainwater near Turners Club. She drowned in a ditch, and although well-wishers retrieved her body, she was already dead. Officers from the Directorate of Criminal Investigations in Kasarani processed the scene, and the body was taken to City Mortuary for identification and post-mortem as investigations continue.
The government has sent condolences to families affected by the ongoing floods, even as it steps up response measures.
At the same time, water levels in major dams have surged. Masinga Dam is now full, forcing controlled releases to prevent damage. Kamburu, Gitaru and Kindaruma dams are also under active regulation to maintain safe levels. Authorities now expect Kiambere Dam to start spilling within the next five days due to sustained inflows from the Aberdare and Mount Kenya regions.
These developments have raised the risk of flooding downstream, especially in Garissa and Tana River counties. The National Disaster Operations Centre is closely monitoring the situation and coordinating response efforts with relevant agencies.
Residents in low-lying areas have been urged to move to higher ground immediately to protect lives and property. Local leaders have also been asked to help spread the warning and support evacuation efforts where necessary.
In Nairobi’s north sub-region, flooding has already disrupted movement and displaced families. In Kasarani, the Street 13 bridge towards Mwiki has been submerged by the Gatharaini River, cutting off access. Several homes have also been affected, with dozens flooded in Maanguo, Maternity and Muirigo areas.
In nearby Mwiki, the Nairobi River remains swollen, while sections of the Njeri House–Nyawai Road have been flooded. A disaster response team led by the Kenya Defence Forces is currently on the ground managing the situation.
The government has urged the public to stay alert as rains are expected to continue in several parts of the country. Kenyans have been advised to follow official updates, report emergencies quickly and cooperate with authorities.
Efforts to respond to the crisis remain ongoing, with a strong focus on protecting lives and reducing the impact of the floods.
