Figure 1.4: Sub-basins of the Lake Victoria Basin

There are several satellite lakes that are part of the LVB. These include (Lake Victoria Basin Commission 2007a): • Lake Wamala (150-250 km²). This is in the Katonga sub-basin in Uganda and is completely surrounded by wetlands. It drains seasonally towards Lake Victoria. The Lake and its wetlands are closely associated with local cultural norms and beliefs and are of traditional and cultural significance to the people of Buganda. • Lake Nabugabo (40 km²). This is about 20 km east of Masaka and 4 km west of Lake Victoria and is surrounded by wetlands (around 220 km²). It is a designated Ramsar site because of its unique flora and fauna. • Lake Mburo (12 km²), Nakivali (31 km²), Kachira (40 km²) and Kijanebalola (42 km²). These form part of the Kijanebalola Swamp complex in the Bukora sub- basin in Uganda.

• Lakes Burera (5.5 km²) and Ruhondo (2.8 km²). These are located in the middle reaches of the Kagera sub-basin in Rwanda. They are connected and drain through the Mukungwa into the Nyabarongo River and into Lakes Muhazi (30 km 2 ) and Mugeseara (35 km 2 ) to the east and south-east, respectively, of Kigali. • Lake Rweru (102 km²) and Cyohoha South (78 km²) – also known as Cohoha. These are on the border between Rwanda and Burundi in the Nyabarongo sub-basin and flow towards the Nyabarongo River. Lake Cyohoha provides outflows during seasonal flood events and Lake Rweru is only recharged by the Nyabarongo River during flood events. • Lake Ihema (9.1 km²). This is on the border between Rwanda and Tanzania in the middle reaches of the Kagera sub-basin and is part of the Kagera riverine wetlands system. • Lake Kanyaboli (10.5 km²). This is fed by the Yala/ Nzoia sub-basins in Kenya, as well as the Yala River waters via an artificial canal.
