About this water

The old border river between Denmark and Germany from 1864 until 1920, flowing through the flat south Jutland marshland. 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.
