The Sennar Dam is a dam on the Blue Nile near the town of Sennar, Sudan. It was built during the 1920s by the British contractor, S Pearson & Sons, Ltd, to a design by engineer Sir Murdoch MacDonald. The dam is 3025 meters (9925 feet) long, with a maximum height of 40 meters (130 feet). It provides water for crop irrigation in the Al Jazirah region.

Construction[edit]

Work on the dam first started in 1914, but was almost immediately interrupted by the outbreak of World War One. Work re-commenced in 1919, the contractors being the Sudan Construction Company, who carried on the work until 1921 when work was stopped for a second time due as it became clear that the estimated cost of the scheme would be considerably exceeded.[1]

In 1922, with further funds obtained, six British firms were invited to submit tenders to complete the dam and to build the connecting canal system. S. Pearson & Sons, Ltd, of London, was successful, and contracted to complete the dam by July 1925.[1] Work began in December 1922, and the dam was finished in May 1925 (John Watson Gibson was Pearson's site agent).[2] Oswald Longstaff Prowde was resident engineer on the dam, which was designed by Sir Murdoch MacDonald.[2][3] Both later became partners in Sir M MacDonald & Partners.
