The Convention on Wetlands came into force for Uganda on 4 July 1988. Uganda presently has 1 site designated as a Wetland of International Importance, with a surface area of 15,000 hectares. A complex of river systems emanating from the Rwenzori Mountains supplying a system of permanent swamps located on Lake George, in the Rift Valley.
Vegetation consists of grassland, woodland, and three major swamp types.
The site supports large mammals, including elephants, hippopotamus, and antelope, and is important for numerous species of wintering Palearctic waterbirds and various notable resident birds. Mine water seepage, agricultural runoff, and effluent inputs are impacting the site. A research station is located on the site. Chemical seepage from Kilembe mines and inflow of agricultural chemicals into the wetland resulting from the Mubuku Irrigation Scheme have led to listing on the Montreux Record in 1990. Ramsar site no. 394.
