About this water

Normandy stream with mixed geology — chalk influence in lower reaches, granite further up. Wild brown trout. Pastoral water, intimate in places, more open in others. Fly-fishing on accessible beats. Spring (April–May) offers good dry-fly potential when insect activity aligns. Some sections may have restrictions; check AAPPMA before visiting.
