Orashi River (also Urashi or Ulasi),[1] is a major river of the lower Niger Delta Basin, and a tributary of Oguta Lake in the southwestern portion, southeastern Nigeria.[2] [3] [4] Orashi takes off from hills of Dikenafai, (latitude 05 045’N, longitude 07 010’E) in Imo State.[5][1] It flows through several towns, including Urualla, Akokwa, Okija, Ihiala, Uli, Oguta, Mgbidi, Omoku, Obiakpo, Ebocha, Ukodu and Mbiama, and empties onto the Altlantic via Bonima River in Rivers State.[5][1]
Inland Waterway
To improve inland waterways transportation in Nigeria, the Federal Government approved the [6] the dredging of the Orashi River from Oguta Lake in Imo State to Degema in Rivers State.[7] The project which was awarded to Simidia S and I International Company in May 2012 was to be completed in 12 months. The 205 kilometers river was expected to be dredged with a bed width of 40 meters, top width of 70 meters and depth below dredging chart datum of 1.5 meters.[8]
Economy
The greater Orashi Region which includes Njaba River basin, has over 35% of the oil wells in the Niger Delta states of Imo State and Rivers State. Crop cultivation, Oil Palm and fishing are the major occupation of the people and source of livelihood.[4]: 3
