Victoria järv (Lake Victoria) on üks maailma suurimaid mageveejärvi. Ta asub kolme riigi vahel: Uganda, Tansaania ja Keenia. Järvega on üks probleem. Nimelt on viimane kaart dateeritud aastaga 1903. Viimase saja aasta jooksul on veetase langenud järves rohkem kui 2 meetrit, mis on põhjustanud palju laevaõnnetusi ning inimkaotusi.
Kaks rootslast on otsustanud viga parandada. Ola Oskarsson ja Göran Frisk on otsustanud järve ära kaardistada.
