The Khashm el-Girba Dam is a gravity and embankment composite dam on the Atbarah River about 4 km (2 mi) south of Khashm El Girba in Eastern Sudan. The primary purpose of the dam is irrigation.

The dam is equipped with canal headworks, located on its left bank, which divert water into a canal. When water levels in the reservoir are low, three pumps move water into the canal.

The main portion of the dam is an earthen embankment; the spillway and irrigation headworks sections are concrete gravity.[1] The dam has a small hydroelectric power station, which was upgraded during the period 2002-04 to its current installed capacity of 10 megawatts (13,000 hp).[2][3]
