The Itimbiri River (Swahili : Mto Itimbiri) is a right tributary of the Congo River, which it joins above Bumba. At one time it was important as a navigable waterway for transporting good from the northeast of the country down to the Congo.

Course

The Itimbiri River originates in Bas-Uélé, then flows through Mongala, and in its lower reaches defines the border between Mongala and Tshopo. [1] The Itimbiri is formed by the confluence of the Rubi River and the Likati River. [2] [lower-alpha 1] The Rubi River originates in the east of Bas-Uélé and flows west through Buta. The Likati River originates to the west, then flows through Likati and southeast to join the Rubi. Likati lies to the south of Bondo on the Uele River. [1]

The Itimbiri flows in a general southwest direction. Water volumes range from 125 to 1,300 cubic metres per second (4,400 to 45,900 cu ft/s), with the main flood in November and a secondary flood in August, and lowest water in February or early March. The river is very winding and generally has a sandy bottom, apart from the section upstream from Ibembo, where the bottom is very hard gravel. During low water the river widens and splits into several branches, making navigation by large vessels difficult. [2] The average elevation is 380.27 metres (1,247.6 ft). [3]

Biology

The Itimbiri, Aruwimi and Lindi/Tshopo rivers are the main right bank tributaries of the Congo River downstream from the Boyoma Falls in the Cuvette Centrale (Central Basin). This is a flat area of lowland rainforest. [4] As of 2015 about 231 fish species had been identified from the Itimbiri. [5] Mormyridae was the most dominant family in the Itimbiri basin as well as in the Aruwimi and Lindi/Tshopo basins. [6]

Human presence

In 1890 the Belgian officers Léon Roget and Jules Alexandre Milz travelled up the Itimbiri River from Bumba, then the Likati River, reached the Uele River in the region of Djabir (Bondo [lower-alpha 2] ) and descended it almost to its junction with the Mbomou River. [8]

A railway line (Vicicongo line) connected Bondo on the Uele with Aketi on the Itimbiri. The line was reopened in April 2005 after being closed for 14 years. [9] At one time the Itimbiri was the second most important tributary of the Congo in terms of tonnage transported after the Kasaï River. It was used for cargo from Aketi, at the head of the Chemins de fer vicinaux du Zaïre (CVZ) down to its mouth, a distance of 255 kilometres (158 mi). Cargo was transferred to the Congo River boats at Bumba, 28 kilometres (17 mi) downstream from its mouth. [2]

Notes

  1. As of August 2020 OpenStreetMap showed the section from the confluence of the Likati and the Rubi down to the confluence of the Tele River and Rubi as the Rubi River. [1] This disagrees with the 1973 description from the Académie royale des Sciences d'Outre-Mer, which seems more plausible. [2]
  2. At the time, towns and villages were given the names of their chiefs. Djabir, named after the Sultan Djabir, was later called Bakango and today is called Bondo. [7]

The Districts of the Belgian Congo were the primary administrative divisions when Belgium annexed the Congo Free State in 1908, each administered by a district commissioner. In 1914 they were distributed among four large provinces, with some boundary changes. In 1933 the provinces were restructured into six, again with boundary changes. The number of districts fluctuated between 12 and 26 through splits and consolidations, first rising, then falling, then rising again.

The Société des Chemins de Fer Vicinaux du Congo, known as CVC or Vicicongo, was a railway company that operated the narrow gauge Vicicongo line and provided trucking services in the northeast Belgian Congo, and then in the Democratic Republic of the Congo between 1924 and 1974. It provided transport for agricultural goods produced in the northeast that were shipped on the Congo River to Léopoldville (Kinshasa). After independence in 1960 there were civil disturbances and the railway was poorly maintained. The company was taken over by the state in 1974. Later there were further disturbances in which the stations were destroyed and the rolling stock used as a source of metal. The track is decrepit and no longer usable.
