Swift currents crossing beech and alder forests. Average depth is 60cm to 120cm. Mostly gravel and pebbles on the bottom with occasional sand. Where the trees do not form canopy above the river, the bottom is covered with vegetation. Numerous trees lying in the river, and an island here and there, provide perfect shelter to fish. The whole stretch has retained its natural characteristics and has never been regulated. Grayling willfully respond to nymphs and wet flies. From time to time surface activity can also be seen.
