Here is a map of Uganda, and if you focus on the waterways in the center, you'll notice the district of Kayunga. It's located between Kamuli on the east, Kampala on the south, Luwero and Nakasongola on the west, and Apac on the north.
The big blue lake is Lake Victoria, aptly named after the Queen of England at the time of its exploration. It is the largest body of water in Africa. From it, the River Nile goes north.
