Residents living along the lower Tana River have been placed on high alert following warnings of possible flooding linked to rising water levels within the Seven Forks dams system.
In a statement issued on April 29, 2026, authorities said heavy rainfall in upstream areas around Mount Kenya has significantly increased inflows into key reservoirs, including Masinga Dam. The surge has prompted controlled water releases at Kamburu, Gitaru and Kindaruma dams to regulate water levels.
Officials warned that the situation could deteriorate if rainfall persists or if Kiambere Dam reaches capacity, potentially sending larger volumes of water downstream and heightening the risk of flooding in vulnerable areas.
Communities in the lower basin, particularly in the Tana Delta, have been urged to remain vigilant as river levels are expected to rise steadily from April 29, with further increases projected by May 1. Low-lying areas are likely to experience early flooding.
The highest flood risk is expected between May 2 and May 3, when water levels could peak and trigger widespread flooding in towns such as Garissa, Hola and Garsen. Floodwaters may also spread across nearby floodplains and delta regions.
Residents have been advised to take early precautionary measures, including moving to higher ground, relocating livestock and securing essential belongings. They have also been cautioned against crossing flooded rivers or walking through fast-flowing water.
Authorities emphasized that following guidance from local leaders and emergency response teams will be critical in reducing the risk to life and property, noting that early action could significantly minimize damage.
