How to fish it · for Brown Trout
When
Fishable through the reserve's long season, last Sunday of February to last Sunday of November — and more consistently than most Tuscan trout water, because the dam release keeps summer temperatures down when free-flowing streams are struggling. Best sport still clusters around the hatch, late morning into the afternoon.
Where
Zone A, from the powerhouse below Bilancino down to the SP129 viaduct, fishes deep glides and runs typical of a regulated tailwater; Zone B below that, fly-only down toward Sagginale and the Muccione confluence, is more varied riffle-and-pool water.
Method
Nymph or dry-dropper covers the tailwater glides near the dam; switch to dries over risers in the softer water lower down. Barbless hooks and immediate release are compulsory throughout.
Kit
9 ft #4 rod, floating line, 9-12 ft leader to 5X. Weighted nymphs for the deeper glides near the dam; a lighter dry-fly setup for the pockets and riffles further down toward Sagginale.
Why this works
Excellent — conditions well-balanced, with water temperature particularly in your favour.
