The Government of Kenya has issued an urgent flood warning following heavy rains that have pushed key dams along the Tana River cascade to critical levels.
Government Spokesperson Isaac Mwaura confirmed that Masinga Dam has reached full capacity, forcing authorities to begin controlled water releases to protect the structure.
“As of 8.00 pm on April 28, Masinga Dam was reported as full, necessitating controlled releases,” Mwaura said.
Rising Pressure Across the Tana Cascade
The situation is not isolated to one facility. Other dams downstream are also under strain due to heavy inflows from the Aberdare Range and Mount Kenya catchment areas.
Dams currently being regulated include:
- Kamburu Dam
- Gitaru Dam
- Kindaruma Dam
Meanwhile, Kiambere Dam is expected to begin spilling within days if current inflow trends continue.
High Flood Risk Areas Identified
Authorities have flagged downstream regions as high-risk zones, particularly:
- Garissa County
- Tana River County
Residents in low-lying areas have been urged to evacuate immediately and move to higher ground to avoid potential disaster.
The National Disaster Operations Centre (NDOC) is actively coordinating response efforts, working alongside multiple agencies to monitor water levels and manage evacuations.
Fatal Incident in Nairobi
As the rains intensify, the human toll is already being felt.
In Nairobi, a tragic incident was reported in Roysambu subcounty, where a woman believed to be around 29 years old was swept away by fast-moving floodwaters near Turners Club in Zimmerman.
Despite rescue efforts by well-wishers, she was pronounced dead at the scene.
Officers from the Directorate of Criminal Investigations processed the scene, and the body was moved to City Mortuary pending identification and post-mortem.
Authorities have since extended condolences to the victim’s family and others affected by the ongoing floods.
Flooding in Kasarani
Parts of Nairobi, particularly Kasarani subcounty, are already experiencing significant flooding.
Key affected areas include:
- Street 13 bridge towards Mwiki—now submerged by the Gatharaini River
- Maanguo area—at least 20 houses flooded
- Maternity area—around 60 homes affected
- Muirigo area—approximately 30 houses inundated
In Mwiki, the Nairobi River has swollen but remains within its banks for now. However, flooding has been reported along the Njeri House–Nyawai Road corridor.
The Kenya Defence Forces are currently leading emergency response operations in the affected areas.
Government Urges Vigilance
With heavy rains expected to persist, the government is calling for heightened public awareness and cooperation.
Residents are advised to:
- Avoid flooded roads and bridges
- Relocate from low-lying areas immediately
- Report emergencies to local disaster offices
- Follow official advisories closely
Mwaura emphasized that coordinated efforts between state agencies and communities will be key in preventing further loss of life.
A Critical Moment
The coming days will be crucial as water levels continue to rise across the Tana River basin.
While controlled releases are necessary to protect dam infrastructure, they significantly increase the risk of downstream flooding—placing thousands of lives and properties at risk.
The situation remains fluid, and authorities have pledged continuous monitoring and timely updates as Kenya navigates one of its most challenging rainy seasons in recent years.
