VuoksiThe Vuoksi (Вуокса, historically: "Uzerva"; Vuokša; Vuoksi; Vuoksen) is a river running through the northernmost part of the Karelian Isthmus from Lake Saimaa in southeastern Finland to Lake Ladoga in northwestern Russia. The river enters Lake Ladoga in three branches, an older main northern branch at Priozersk (Käkisalmi), a smaller branch a few kilometers to the north of it, and a new southern branch entering further southeast as Burnaya River (Finnish: Taipaleenjoki), which has become the main stream in terms of water discharge.
