How to fish it · for Brown Trout
When
Spring and early summer once the Abetone snowmelt settles, then again through autumn. The Lima is a proper torrente — it can run high and coloured after rain, so check conditions before making the drive up the valley.
Where
Pocket water and boulder-strewn runs through the stretches around Lucchio and down toward Fornoli; the no-kill sections hold the more confident fish, less pressured than the open water at either end.
Method
Short, accurate casts into pockets and seams beat long fine leaders on this kind of broken water. Barbless or crushed-barb hooks throughout the no-kill zones, two flies maximum, immediate release.
Kit
9 ft #4 rod for the pocket water, floating line, 9 ft leader to 5X. Weighted nymphs (Hare's Ear, Pheasant Tail, Perdigón) for searching; a few searching dries for the calmer pools.
Why this works
Water at 20.1°C — above the brown trout caution line (18°C). Fish dawn or dusk only. Land it fast, wet hands, no air shots.

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.
