A Júcar tributary draining the Requena-Utiel plateau in inland Valencia province — wine country rather than classic trout ground.
Why this works
Very poor — water clarity is working for you, but water temperature is the limiting factor today.

Barbel fly box
Cooling water through September–November drives barbel into deeper, steadier runs and the slower glides below gravel riffles. Feeding activity remains high as fish build reserves before winter. Larger nymph profiles and crayfish patterns work better in autumn than the small-nymph summer approach. Cover more water — barbel move more actively in autumn, patrolling runs rather than sitting static. After heavy rain the Squirmy Worm and San Juan Worm become the standout options as invertebrates drift in coloured water.
Hook 6–10 · Fly
Barbel are significant predators of signal crayfish (Pacifastacus leniusculus) in English rivers, and invasive crayfish are present across much of Europe.
