About this water

Lower Austrian alpine river flowing from limestone foothills through St. Pölten to the Danube, part of the classic Austrian trout-grayling zone. Brown trout and grayling in the upper sections. Included provisionally—stronger river-specific sourcing would help confirm grayling populations and seasonal patterns.
