About this water

The fish are local-strain brown trout under strict management: fly-only, barbless, no-kill on the designated beats, with the local AAPPMA taking the stewardship seriously. The water is low-pressure, clean, and genuinely uncrowded — there are days you'll fish for hours without seeing another angler. Match the olive in spring, switch to caddis by mid-June, and keep a few terrestrials for the low-water afternoons. Short rods, long leaders, quiet approach. The river is intimate enough that you'll be casting under overhanging alder as often as you're casting across open water. Not a destination — a reason to slow down and pay attention.

Hatches & food

In freestone rivers of the Massif Central, resident brown trout feed through a spring build-up of olives and stoneflies into a long summer of caddis and small buzzers, with terrestrials becoming important from early summer; higher volcanic plateaux and colder headwaters tend to run later than the lower freestones.
