Lake Cyohoha South or Cyohoha Sud as it is known in Rwanda or Lake Cohoha in Burundi is a small lake in East Africa.
Name
In Rwanda, the lake is known as Cyohoha South to differentiate it from the nearby much smaller Cyohoha North 10 miles north in Rwanda.
In Burundi, it is simply known as Cohoha.
Location
Lake Cyohoha is ten miles West of the larger Lake Rweru, the second lake on the Rwanda - Burundi border.
It is a narrow yet very long lake with many branches.
It is largely bisected by the border between Rwanda and Burundi, however, its southern portion extends entirely into Burundi.
Lake Cyohoha is {{convert|32|km}} long, and has an average width of {{convert|1|km}}. The maximum width is {{convert|2|km}}.
The lake covers {{convert|74|km2}}, of which {{convert|19|km2}} are in Rwanda and {{convert|55|km2}} belong to Burundi.
Hydrology
Lake Cohoha is fed by the Rugamura Marsh, which in turn is fed by the Gatunguru River, the Runyoni River and the Nduruma River.
The Nduruma River is fed by the Matonnyanga to the north of Mukerwas colline, by the Runyuiya to the south of Rwimbogo colline and by the Gasuga, which forms between the Kabirizi and Butihinda collines.{{sfn|Kirundo USDMA}}{{efn|There is some confusion between the Nduruma tributary of the Rugamura Marsh and the larger Nduruma River further to the east. A 2012 report on investment opportunities in renewable energy in Burundi includes a map that shows the larger Nduruma River extending beyond its source on the Defense Mapping Agency's 1994 map, then turning southwest and flowing to Lake Cohoha.{{sfn|Investment opportunities in renewable energy|p=14}}
The reality is that the eastern Nduruma River is fed by an unnamed tributary that flows from the Butihinda colline, not far from the source of the Gasuga tributary of the western Nduruma River.{{sfn|Kirundo USDMA}} }}
Lake Cyohoha South just as its cousin Cyohoha North empties into the Akanyaru River via a series of marshlands that connect these lakes to the river.{{cite web |title=Akanyaru River |url=https://www.explorerwandatours.com/attractions/akanyaru-river.html |website=Explore Rwanda Tours |accessdate=16 July 2020}}{{sfn|Lac Cohoha USDMA}}
