The lake is situated in Oguta about 50 kilometres (30 mi) from the junction of the Ndoni and Orashi River. It is about eight kilometres (5 mi) long from east to west and 2.5 kilometres (1+1⁄2 mi)wide.[4] The stream from Njaba River is the major inflow to Oguta Lake.[citation needed] The other three tributaries are Awbana, Utu and Orashi. The Orashi River flows past Oguta Lake in its southwestern portion.
The lake is important to the people of oil-rich Njaba River basin including Oguta, Orsu, Mgbidi, Nkwesi, Osemotor, Nnebukwu, Mgbele, Awa Awo-Omamma Akabo as a source of water, fish, tourism and an outlet for sewerage.[5] Uhamiri is the goddess of the lake.[6]
The river route Njaba and Orashi via Oguta Lake to the coast, passing through Awo-omamma, Mgbidi, Oguta, Ndoni, Abonnema, Degema made Oguta, Osemotor, Awo-omamma and surrounding towns important commercial centres of international trade mainly for oil palm.[citation needed] Oguta Lake also served as a Biafran army marine base during the Nigerian Civil War.[7]
