This map of the Sigulu region, in Namayingo District in eastern Uganda, was issued by the Lands and Surveys Department of Uganda in 1963, and is based on aerial surveys carried out in 1948, 1952, and 1960, and on field survey data. The map shows the heavily forested islands of Bugana and Sigulu in the northeastern part of Lake Victoria and the adjacent coastal areas in Uganda and Kenya. Rocks, a navigational hazard, are indicated. An index grid in the lower left identifies adjoining sheets to this detailed survey map. The scale is 1:50,000. Distances are given in kilometers and miles. Elevations are in feet. Previously called Victoria Nyanza, Lake Victoria is the largest lake in Africa, the second largest freshwater lake in the world (after Lake Superior in North America), and the chief source of the Nile River. Containing many islands and archipelagos and numerous reefs, the lake lies mainly in Tanzania and Uganda and also borders on Kenya.
