Ranked for today
Brown Trout fly box

More balanced than the mountain-river pack. French nymphing still matters, but there is more room for dries, spiders and general searching flies.

About this water

30 km of 1st-category Vosges mountain river from Oberbruck to Masevaux. Strict fly-only, no-kill, barbless-hook regulation protects local-strain wild trout. Granitic freestone with excellent Baetis and caddis. Every fish represents generations of wild breeding. Spring through early autumn. Check Haut-Rhin regulations for permits and access.

Hatches & food

In Vosges granite catchments, trout in cool freestone streams feed on early and spring olives once levels settle after winter, daytime stoneflies over clean, stony runs, a broad band of evening caddis supported by rich bug life in the region, steady small buzzer activity on mild days, and terrestrials strongest where the river is hemmed in by forest.
