The Umgeni River or Mgeni River is a river in KwaZulu-Natal, South Africa. It rises in the "Dargle" in the KZN Midlands, and its mouth is at Durban, some distance north of Durban's natural harbour. It is generally agreed its name means "the river of entrance" in Zulu, though other meanings have been suggested. The river is approximately 232 km long with a catchment area of 4432 km2. The Howick Falls are some famous waterfalls on the Mngeni.

Tributaries

A noteworthy tributary is the Msunduzi River, which joins it between Nagle and Inanda dams. Higher up its course, the Msunduzi (or 'Dusi' for short) passes through the KwaZulu-Natal capital Pietermaritzburg. A famous downriver race, the Dusi Canoe Marathon takes place between the capital and Durban, attracting thousands of canoeists for the three-day event held every year January. A small tributary that has an impact exceeding its size and length is the Lions River which joins the Umgeni about 4 kilometers upstream of Midmar Dam (near Lidgetton). Its significance lies in the fact that it is a part of a water transfer scheme between the Mooi River (Spring Grove Dam) and the Umgeni. A smaller tributary close to its mouth is the 26 km Palmiet River, which should not be confused with the Palmiet River in the Western Cape.

Dams

Presently the Umgeni is part of the Mvoti to Umzimkulu Water Management Area. There are four large dams in its catchment basin:

Ecology

The Scaly Yellowfish (Labeobarbus natalensis) is a fish found in the Umgeni River System as well as in the Umzimkhulu, Thukela, Umkhomazi and the Umfolozi. It is a common endemic species in KwaZulu-Natal Province and lives in different habitats between the Drakensberg foothills and the coastal lowlands.

History

It is assumed that Vasco da Gama replenished his fleet's water supply at the Umgeni mouth on Christmas Day, 1497, and so named the region Natal, Portuguese for Christmas. The river then acquired the name "River of Natal". 130 years later the Umgeni was crossed by Nathaniel Isaacs on his way to visit Shaka. At some point before October 1825, settlers and natives led by Francis Farewell began construction of Fort Farewell between the uMngeni River and Port Natal.
