The Orashi River flows past Oguta Lake in its southwestern portion. Economic ImportanceThe lake is important to the people of oil-rich Njaba River basin including Oguta, Orsu, Mgbidi, Nkwesi, Osemotor, Awo-Omamma and Izombe as a source of water, fish, tourism and an outlet for sewerage.[8] Uhamiri is the goddess of the Lake.[9] Trade RouteThe river route Njaba and Orashi via Oguta Lake to the coast, passing through Awo-omamma, Mgbidi, Oguta, Ndoni, Abonnema, made Oguta, Osemotor, Awo-omamma and surrounding towns important commercial centres of international trade mainly for oil palm.[10] Oguta Lake also served as a Biafran army marine base during the Nigerian Civil War.[11] Footnotes1. ^{{Cite web|title=Oguta Lake|website=Ramsar Sites Information Service|url=https://rsis.ramsar.org/ris/1757|accessdate=25 April 2018}} 2. ^{{cite journal|url=https://books.google.co.uk/books?id=XyyxCwAAQBAJ&pg=PA355&lpg=PA355&dq=okwelle&source=bl&ots=jcmrldePu1&sig=AM_vCLasJ40dL1QEF3AXSvPAqXg&hl=en&sa=X&ved=0ahUKEwjYg8ew3e7MAhVlGsAKHXepC0U4MhDoAQg7MAY#v=onepage&q=okwelle&f=false |title=Eastern Nigeria|first= Barry|last=Floyd|date=1969 |page=89 |publisher=Springer|accessdate=May 22, 2016}} 3. ^{{cite journal|url=http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.402.4399&rep=rep1&type=pdf |title=Inventory of the Quaternary Geology and the Evolution of the Oguta Lake, in Southeastern Nigeria|first= Bruno Ndicho|last=NFOR|display-authors=etal|journal= World Journal of Engineering and Pure and Applied Science |issue=2249-0582 |date=2012 |page=2 |volume=2:1|publisher=Department of Geology, Anambra State University, Uli, Anambra State, Nigeria}} 4. ^{{cite journal|url=http://www.iiste.org/Journals/index.php/JNSR/article/download/.../13026 |title=Assessment of Water Quality and Heavy Metal levels of Fish Species in Oguta Lake, Imo State Nigeria|first= JOHNBOSCO EMEKA|last=UMUNNAKWE |journal=Journal of Natural Sciences Research |issue=2225-0921 |date=2014 |page=1 |volume=4|display-authors=etal}} 5. ^{{cite journal|url=https://rsis.ramsar.org/RISapp/files/RISrep/NG1757RIS.pdf |title=Oguta Lake|first=Prof. O.O.|last=OGUNKOYA |journal=Information Sheet on Ramsar Wetlands(RIS) |issue=2006-2008 |date=2007 |page=4}} 6. ^{{cite journal|url=http://onlineresearchjournals.com/aajoss/art/77.pdf |title=The Aro, Host Communities And Continuties In Intergroup Suspicion In The Oguta Area Since Pre-colonial Times |page=1 |first=Uche Uwaezuoke |last=Okonkwo |journal=Afro Asian Journal of Social Sciences |volume=2 |issue=2.4 |date=2011 |issn=2229-5313}} 7. ^{{cite journal|url=http://onlineresearchjournals.com/aajoss/art/77.pdf |title=The Aro, Host Communities And Continuties In Intergroup Suspicion In The Oguta Area Since Pre-colonial Times |page=1 |first=Uche Uwaezuoke |last=Okonkwo |journal=Afro Asian Journal of Social Sciences |volume=2 |issue=2.4 |date=2011 |issn=2229-5313}} 8. ^{{cite web |url=http://www.ilec.or.jp/database/afr/afr-18.html |title=OGUTA LAKE |publisher=www.ilec.or.jp |accessdate=2008-06-08}} 9. ^{{cite book|title=Igbo women and economic transformation in southeastern Nigeria, 1900-1960 |first=Gloria |last=Chuku |publisher=Routledge |year=2005 |isbn=0-415-97210-8 |page=26}} 10. ^{{cite journal|url=http://onlineresearchjournals.com/aajoss/art/77.pdf |title=The Aro, Host Communities And Continuties In Intergroup Suspicion In The Oguta Area Since Pre-colonial Times |page=1 |first=Uche Uwaezuoke |last=Okonkwo |journal=Afro Asian Journal of Social Sciences |volume=2 |issue=2.4 |date=2011 |issn=2229-5313}} 11. ^{{cite web|url=http://www.worldlakes.org/lakedetails.asp?lakeid=8355|title=LakeNet -Lakes|publisher=www.worldlakes.org|accessdate=2008-06-08}} External links
