About this water

DTU names Kongeåen among the rivers where salmon catches must be reported through the national Fangstjournal — a sign that a genuine salmon run still passes through. A quiet, unassuming sea trout river with wild browns in the upper sections and a secondary salmon run. Small-scale water that rewards a careful approach and a well-presented nymph. Day tickets from local associations. A sand-and-clay bed shapes this river. Atlantic salmon are managed under strict national quotas (DTU Aqua) — each river runs a limited annual kill quota and switches to catch-and-release once it is filled; check the quota before fishing.
