Drūkšiai, also called Drysviaty or Drysvyaty,[1] or Drisvyaty (Belarusian: Дрысвяты, pronounced [drɨˈsʲvʲatɨ]; Russian: Дрисвяты) is the largest of the Braslau lakes located partly in the northeastern part of Lithuania and partly in the Vitebsk Voblast, in Belarus.

The lake water was used to cool the reactors of Lithuania's now decommissioned Ignalina Nuclear Power Plant.

The greatest depth of the lake is 33.3 m, and the average depth is 7.6 m. The basin of the lake was formed during the movement of the glaciers by two perpendicular channels, which expanded north to south and west to east.

The shallowest part is on the south ridge of the lake, its depth is approximately between 3 and 7 meters.
