The Kenyan government plans to upgrade the Masinga Dam, the country's largest hydropower reservoir on the Tana River, to increase energy capacity and regulate flooding. The project, announced by the National Environmental and Management Authority (NEMA), involves raising the dam's spillway and installing a new one.

• The spillway wall will be raised by 1.5 meters, increasing water storage by 173 hm3.
• The dam is located in Embu and Machakos County, with its extended zone impacting Kitui, Garissa, and Tana River counties.
• Anticipated impacts include occupational health risks, social disturbance, and vegetation degradation, requiring contractors to implement strict safety and environmental measures.
