Flying along the White Nile on the way to Bor from Juba is quite interesting. While the passable part of the Nile can be quite narrow, the river actually span quite some area. Bor is just about at the start of the Sudd thus there are islands, some permanent others that dissapear with the yearly rain. In addition there is many “lakes” forming in the inaccessible areas while the river expands and contracts. Its quite interesting to note that of all the water coming from Lake Victoria 90% will dissapear into the Sudd in North Jonglei.
