The river begins approximately at , south of the [[Jebel Miri, South Sudan|Miri Hills]], approximately 7 km north of the village of [[Mussikidolk, South Sudan|Mussikidolk]] and 60 [[kilometer|km]] west of the state capital [[Juba, South Sudan|Juba]].<ref name=rusmap/> It runs mostly in the northeast direction, being joined by major tributaries from the same general source region at and .<ref name=rusmap/> Near it changes to an eastward general direction. After about 32 km (beeline; near , about 20 km due north of Juba, and 6 km northwest of [[Luala, South Sudan|Luala]]) it makes a broad curve 6 km south and southeast of [[Jebel Lado, South Sudan|Mount Lado]], an isolated hill with peak at 1006 m altitude, that dominates the landscape of the area.<!--Mount Lado, Mount Nyerkenyi [https://ift.tt/2YmD0yL], peak-->

From there it flows northeast for about 14 km, almost parallel to the White Nile, until a point 0.5 southwest of the village of [[Lado Koda, South Sudan|Lado Koda]] (). There the course bends sharply to the southwest for another 2.5 km, ending on the White Nile, about 35 km downstream (north) of Juba .<ref name=gmap/><ref name=detmap/> The annual flow has been estimated at about 60 million [[cubic meter|m<sup>3</sup>]].<ref name=jica/>

For the last 18 km, the river is flanked by a strip of [[floodplain]]s about 0.5 km wide,<ref name=gmap>Google Maps: "[https://ift.tt/2TyAf9G Koda River]". Acessed on 2019-03-23</ref> with a total area of 3159 [[hectare|ha]], including the riverbed. Along that valley, the altitude drops from 470 m (at ) to 435 m.<ref name=futw2012/>

The river flows near the villages of [[Wulikare, South Sudan|Wulikare]], [[Logogvi, South Sudan|Logogvi]], [[Ludo Kenyi, South Sudan|Ludo Kenyi]], [[Luala, South Sudan|Luala]], and Lado Koda. Wulikare is located 0.5 km south of the river and 29 km northwest of Juba.<ref name=detmap>(2013): "[https://ift.tt/2YkDt4l Sudan: Central Equatoria State - Detailed Transport Map (as of 17 Jan 2013)]".

==History and demographics==
The area near the White Nile is the historic homeland of [[Bari languages|Bari]]-speaking people.<ref name=nal1937/>

The [[Nyangwara tribe, South Sudan|Nyangwara tribe]] in the [[Miri Hills]], [[Mongalla province]] believed that Lotome, the first remembered ancestor of the [[Gwokorongo, South Sudan|Gwokorongo]] chiefs, lived at [[Dogeleng, South Sudan|Dogeleng]] near the Koda River around 1800.<ref name=nal1937>L. F. Nalder (1937): ''A Tribal Survey of the Mongalla Province'', page 193. Oxford University Press.</ref>

As of 2018, the [[South Sudan war]] was still affecting in the area.<ref name=cedass/>

==Economics==
As of 2012,only about 10% of the area in the flood valley was cultivated, mostly for [[maize]], [[sorghum]], [[cassava]] and [[millet]].<ref name=futw2012>(2012): "Jebel Lado focal area". ''Assessment of the Irrigation Potential in Burundi, Eastern DRC, Kenya, Rwanda, South Sudan, Tanzania and Uganda - Final Report'', [https://ift.tt/2TyAfqc Appendix South Sudan], Section 3, pages 98-121. Report 114, FutureWater consultants, Wageningen, Netherlands. Warning: This report icorrectly calls the river "Bahr el-Jebel" ("Mountain River"), which is actually the local name of the White River; and calls its flood valley "Jebel Lado" which is the name of the nearby mountain ("Jebel" or"Jabal" being Arabic for "Mountain"). Also, while the satellite images are useful, the panoramic views may be stock photos.</ref>

As in most of South Sudan, the local population among the poorest in the planet. The area has has been of interest to international relief agencies that produced plans for possible [[irrigation]] projects<ref name=jica/><ref name=futw2012/> or actually created and managed such installations and model farms.<ref name=cedass>"[https://ift.tt/2YmeZHP The Jebel Lado Project]" CEDASS website, Accessed on 2019-03-23</ref> For example, the Japan International Cooperation Agency (JICA) offered a study of the construction of three dams — incuding one on the Koda river, a couple km west of Wulikare — to collect and store water for irrigation in the region of Jalang.<ref name=jica>"[http://open_jicareport.jica.go.jp/pdf/12249215_04.pdf Irrigation Development Master Plan]".

Warning: The authors seem to have obtained all their geographic data from Google Earth and Google Maps, so the names and locations of the towns may be incorrect.</ref>

==Flora and fauna==
Much of the area has natural vegetation consisting of grasses, bushes, and sparse trees.<ref name=jica/>
