About this water

The Warche flows through proper Ardennes country — slate and beech forest — and it fishes like an honest working river ought to. Brown trout and grayling share the riffles and pools with easy grace. Good spring olives, summer caddis, the sort of hatch calendar that makes you want to sit down with a river-keeper and a notebook. It responds fast to rain, which means either a gift or a curse depending on when you arrive. Club-managed beats give it a lived-in feeling, the sense that someone's been fishing this water properly for a very long time.
