How to fish it · for Brown Trout
When
Spring and early summer once the lake's outflow settles, then again in autumn once the tourist traffic through the gorge has eased off. Midday can go quiet in the brightest weeks — mornings and evenings are more reliable.
Where
Pocket water below the gorge walls, the broken runs where current piles against limestone, and the calmer glides near Anversa degli Abruzzi. The trout here favour structure over open water — read the gorge itself as much as the river.
Method
Upstream nymph through the broken pocket water is the reliable method; switch to a searching dry-dropper on the calmer stretches near the reserve entrance. Wading is limited in the gorge proper — plan your access before you commit to a pool.
Kit
9 ft #4 rod for the pocket water, floating line, 9-12 ft leader to 5X. A small box of weighted nymphs (Hare's Ear, Pheasant Tail, Perdigón) does most of the work; carry a few searching dries for the quieter glides.
Why this works
Water at 22.2°C. This is the line where catch-and-release kills brown trout. Do not fish for them today.

What would change the calculation
Cooler water — back toward the 10–16 °C ideal band — would lift the score and ease welfare.
The dawn and dusk windows score higher than the midday lull.
