How to fish it · for trout
When
Current conditions suit Lac de Villerest well for summer tactics. The ripple should help fish move and feed more confidently. Very warm conditions — trout have a narrower safe zone of cool, oxygen-rich water. Fish only at first light or last light, use barbless hooks, keep fish in the water during release, and stop if fish struggle to recover. Early morning is often the most productive window in summer — make the most of it.
Where
Start with Pheasant Tail Nymph (14-18) — on the point — slow figure-of-eight retrieve. If that does not produce, switch depth or speed before changing the pattern entirely.
The plan
Plan A

Start with Pheasant Tail Nymph (14-18) — on the point — slow figure-of-eight retrieve. If that does not produce, switch depth or speed before changing the pattern entirely.

Plan B

Fish early and late, try deeper during the heat of the day with a fast-sinking line.

Watch for

Sedge should come on through the afternoon as the water warms.

Either bank or boat

Good ripple suits both bank and boat. Bank: work inflows, dam walls, and points. Boat: broadside drift covering wind lanes.

About this water

Villerest is the big Loire reservoir above Roanne — seventeen kilometres of drowned river gorge held back by the 1984 dam, sitting at around 320 metres on the Forez granite. It is a second-category water first and foremost, which means pike, pike-perch and perch are the staples, but the upper end of the lake where the Loire itself comes in still holds trout and grayling in numbers that would surprise anyone who only knows Villerest from the motorway crossing. The fly fishing is a mixed proposition: pike on streamers along the drowned banks of the old gorge, and trout/grayling dry fly or nymph in the upper Loire tail where the river still runs free. The water level drops significantly through summer for Loire downstream flow support, which exposes the old gorge walls and changes the fishable margins week by week. Worth a visit for the predator fly fishing if nothing else.

Why this score
  • Wind conditions (ripple) closely match what this water fishes best in.
  • Cloud cover (cloud) suits the fishery well.
  • Wind-blown Terrestrials are in their seasonal window, boosting the chance of targeted feeding.
