The Imo River (Igbo:Imo) is located in southeastern Nigeria and flows 240 kilometres (150 mi) into the Atlantic Ocean. In Akwa Ibom State, the river is known as Imoh River, that is, Inyang Imoh, which translates to River of Wealth (Ibibio: Inyang means river or ocean, and Imoh means wealth). Its estuary is around 40 kilometres (25 mi) wide,[3] and the river has an annual discharge of 4 cubic kilometres (1.0 cu mi)[4] with 26,000 hectares of wetland.[5][6] The Imo's tributary rivers are the Otamiri and Oramirukwa.[7] The Imo was cleared under the British colonial administration of Nigeria in 1907–1908 and 1911; first to Aba and then to Udo near Umuahia.[8]
The deity, or Alusi of the river is the female Imo who communities surrounding the river believe to be the owner of the river. Mmiri in Ibo or Igbo language means water or rain.
A festival for the Alusi is held annually between May and July.[9] The Imo River features an 830-metre (2,720 ft) bridge at the crossing between Rivers State and Akwa Ibom State.[10] The river god, or Arushi, is a female imo, and the communities surrounding the river believe her to be the river's owner.
Imo river was reported by the world Health Organization as one of the most polluted rivers in Nigeria.[11]
