About this water

The Traun is one of those rivers that teaches you to slow down. Lake-fed limestone water flowing through the Salzkammergut, holding trophy brown trout and grayling of genuine quality. The Gmundner Traun below Traunsee is the working section—a bucket-list river where careful nymphing and selective dry fly work pay dividends.
