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, which was located about twenty five kilometres south of Cairo. Built around 2600 BC for flood control, the structure was 102 metres long at its base and eighty seven metres wide. It was destroyed by a flood while it was still under construction.

    The devil take one party and his dam the other!
    William Shakespeare (1564–1616)

    Without [diversion] we would be in a state of weariness, and this weariness would spur us on to seek a more solid means of escaping from it. But diversion amuses us, and leads us unconsciously to death.
