The Roseires Dam () is a dam on the 
The dam was completed in 1966, initially for irrigation purposes. A power generation plant, with a maximum capacity of 280 megawatts, was added in 1971.
Extension Project
The original maximum height of the dam was 68 m, which increased to 78 m in 2013 and the dam is now 25 km long. The dam contains five 3 m x 5 m low level sluice gates designed to pass floods and sluice sediment. The dam contains a gated ogre spillway with a discharge capacity of 694 m3/s. In addition, the dam was designed with five low level outlets with a discharge capacity of 5,208 m3/s to pass floods and sluice sediment through the reservoir. The extension allowed the reservoir's design capacity to be increased from 3 km3 to 7.4 km3, thereby increasing the flood-control value of the dam.
