A southern Jutland river system draining to the Wadden Sea near Tønder, close to the German border. DTU's national catch-journal grouping includes Vidå among the regulated western salmon rivers, making it credible as a migratory system, but it is not yet proven as a standout sea-trout destination from verified sources. Low-gradient marshland water with sea trout and salmon present. The proximity to the border means cross-border anglers from Schleswig-Holstein fish it too. Association-managed access.
