Reservoir levels across Kenya’s main hydropower dams remained within controlled operational thresholds, even as sustained rainfall continued to feed the country’s major catchment areas, according to an update from KenGen.
The heavy inflows significantly boosted Kenya’s electricity supply, with hydropower producing a robust 9.57 million kilowatt-hours on May 4 to the national grid.
Managing Director and CEO, Eng. Peter Njenga said all dams were operating within safe parameters, with controlled releases in place where necessary. The network of reservoirs, many of them along the Tana River cascade, is currently balancing two critical functions: generating low-cost electricity and moderating downstream water flows amid ongoing rains in the Mt. Kenya and Aberdare regions.
Summary Table of Seven Forks Dams Levels night of Monday, May 4, 2026:
| Dam | Current Level (masl) | Full Supply Level (masl) | Status Summary |
| Masinga | 1,057.43 | 1,056.5 | Above full supply Level; controlled overflow |
| Kamburu | 1,003.62 | 1,006.5 | Within range |
| Gitaru | 922.92 | 924.5 | Within range |
| Kindaruma | 779.72 | 781.2 | Within range |
| Kiambere | 700.91 | 700.0 | Slightly above; actively managed. |
At Masinga, the country’s largest reservoir, water levels rose slightly above Full Supply Level (FSL) but within spillway design capacity, reaching 1,057.43 meters above sea level. Eng. Njenga said the water from Masinga was being discharged to the lower dams under tightly managed protocols, with both power-generating units functioning optimally.
Other dams in the cascade remained within operational range. Kamburu, Gitaru, and Kindaruma all reported healthy generation across their units, while Kiambere, being marginally above its full supply level and actively managed.
Despite the high inflows, the KenGen CEO emphasized that there was “no cause for alarm,” noting that all systems are under continuous, around-the-clock supervision.
Hydropower remains among the country’s most economical energy source, and the increased output may contribute to reduced reliance on thermal generation, a shift that could ease electricity costs for consumers.

Authorities, however, urged caution for communities living downstream, particularly along the Tana River. Residents in low-lying and flood-prone areas have been advised to avoid riverbanks and remain attentive to guidance from local officials as rainfall persists.
KenGen said it would continue issuing updates as conditions evolve, underscoring its commitment to managing water resources for both national power supply and public safety.
