About this water

Small Normandy chalk stream flowing toward the Seine estuary where spring water keeps temperature stable and trout selective. Wild brown trout and grayling. Classic patterns: small olives and ephemeralids (16–18), sedges (14–16) evening. Pocket water where reading current and understanding trout lies matters more than distance casting. Some access restricted; check AAPPMA.
