ABSTRACT. Lake trout occurred in Wdzydze Lake in summer only in the southern, deep basin. At this time trout was harvested at the depth of over 20 m. For the rest of the year, trout was found in the entire lake complex, in shallow and deep basins. Seasonal changes of lake trout distribution might have been caused by changes of thermal and oxygen conditions in the lake.
