Diversion dam

Diversion dam

A diversion dam is the term for a dam that diverts all or a portion of the flow of a river from its natural course. Diversion dams do not generally impound water in a reservoir. Instead, the water is diverted into an artificial water course or canal, which may be used for irrigation or return to the river after passing through hydroelectric generators, flow into a different river or be itself dammed forming a reservoir.

The earliest diversion dam - and the second oldest dam of any kind known - is the Ancient Egyptian Sadd-el-Kafara Dam at Wadi Al-Garawi, located about 25 km south of Cairo. Built around 2600 BC for flood control, the structure was 102 m long at its base and 87 m wide. It was destroyed by a flood while still under construction.[1][2]
