The Roseires Dam was built in 1966 on the Blue Nile River in Sudan, creating the Roseires Reservoir visible here towards the bottom. The dam has a nominal volume of 36.3 km3. Much of the water impounded at Roseires is used to expand and intensify agriculture on the Gezira Scheme.

Raising the crest of Roseires Dam is still on the agenda, especially because low flows on the Blue Nile have cut cropping intensities on the Gezira about 15%. Instead of 1,500,000 irrigated acres, the total irrigated area is closer to 1.2 million, while the cotton crop covers 385,000, not 500,000. As the storage capacity at Roseires declines, these figures may be expected to fall further.
