The Ruki () is a river in the Democratic Republic of the Congo. It is a left tributary of the Congo River. It may be seen as the lower reach of the Busira River, which in turn may be seen as the lower reach of the Tshuapa River.

Location

The Ruki is a major river in the Cuvette Centrale of the middle Congo River basin. The watershed covers about 14000000 km2. The drainage basin is almost entirely pristine lowland forest and swamp forest. As of 2020, 248 species of fish had been identified in 26 families. The main rivers are the Ruki-Busira, Momboyo-Luilaka, Tshuapa, Lomela and Salonga. The most important town in the river basin is Boende on the Tshuapa, 29 km upstream from where it joins the Lomela to form the Busira.

The Ruki River forms above Ingende where the Momboyo River joins the Busira River from the left and flows in a west-northwest direction. It enters the Congo from the east, flowing past the north of the town of Mbandaka. The Ruki and its main tributary the Busira can be navigated year round, since the depth is always more than 1 m and reaches 2 m in the flood period. High water is in March-April and November. Low water is in February and June-July.

The Ruki itself is just 103 km long, and extends downstream from the mouth of the Momboyo, which is 2 km above Ingende. Higher up it is called the Busira as far as the confluence of the Tshuapa and the Lomela. The Busira section is 305 km long, and the whole Ruki-Busira waterway is 408 km long. The Ruki-Busira receives four navigable tributaries: the Momboyo at 103 km from its mouth, the Salonga at 233 km, just upstream from Lotoko, and the Tshuapa and Lomela which converge to form the river.

Colonial period

The explorer Henry Morton Stanley visited the region, and called the Ruki the Mohindu River. A local man from Bungata named the river Buruki (Ruki) or Mohindu, meaning "Black". Stanley explored it for about 80 mi, and based on its size and reports of the local people he estimated that it might be navigable for about 650 mi.

The African Queen

The Ruki River was used as a location for the movie The African Queen starring Humphrey Bogart and Katharine Hepburn. A 1951 article in Life magazine describes how the influx of filmmakers broke the "sweltering monotony of life along the dank, disease-ridden shores" of the river. Forest was cleared to create a "cluster of tasteful native huts". Filming took seven weeks.
