Seven Forks Dams Release Water as Tana River Flooding Alert Issued for This Weekend
Tana River, 1 May 2026
Heavy rainfall around Mount Kenya has forced controlled water releases from major hydroelectric dams, triggering flood warnings for thousands of residents along the Tana River. Peak flooding is expected between Saturday and Sunday, with Garissa, Hola, and Garsen at highest risk as water levels continue rising sharply.
Dam Operators Respond to Mounting Water Pressure
The Kenya Electricity Generating Company has initiated controlled water releases at three critical Seven Forks facilities: Kamburu, Gitaru, and Kindaruma dams [1]. These releases come as heavy rainfall has caused a sharp rise in water inflows into dams in the upper Tana region around Mount Kenya [1]. The Ministry of Interior and National Administration has confirmed that water levels in key reservoirs like Masinga Dam have risen sharply [1], prompting the coordinated response to prevent catastrophic dam failures whilst managing downstream flood risks.
Critical Flood Window Approaches
Water levels in the Tana River are expected to keep rising over the next few days [1], with the highest risk period for flooding projected to be between Saturday, 2 May 2026, and Sunday, 3 May 2026 [1]. During this critical window, water levels are expected to reach their peak, potentially triggering widespread flooding in areas including Garissa, Hola and Garsen [1]. The Ministry has warned that floodwaters may potentially spread across nearby floodplains and delta regions [1], affecting agricultural lands and rural communities that depend on these areas for their livelihoods.
Government Issues Urgent Safety Measures
The Ministry of Interior and National Administration has advised residents along the lower Tana River to move to higher ground ahead of peak flooding expected between Saturday, 2 May and Sunday, 3 May [1]. Authorities have issued specific guidance for residents to take early precautionary measures, including moving to higher ground where possible, relocating livestock and securing essential belongings [1]. The Ministry has also warned against crossing rivers or walking through flowing water [1], emphasising the deadly risks posed by fast-moving floodwaters during peak conditions.
Escalating Risk Factors Compound Threat
The situation remains highly volatile as the Ministry has warned that if rainfall continues or if Kiambere Dam reaches its limit, more water may flow downstream, raising the risk of flooding in affected areas [1]. This escalating risk scenario reflects the delicate balance dam operators must maintain between preventing upstream dam failures and managing downstream flood impacts. The current flooding threat echoes the devastating El Nino floods of October 2023, when floodwaters inundated roads along the Garissa-Mombasa road in Tana River County [1], demonstrating the vulnerability of critical infrastructure to extreme weather events in this region.
