- Free fishing
- Fly only
Start with CDC Emerger (16-20) on a As per local method. If that does not produce, switch depth or speed before changing the pattern entirely.
Fish early and late, try deeper during the heat of the day with a fast-sinking line.
Evening tends to be the best period in summer — stay late if you can for a sedge or spinner fall.
Good ripple suits both bank and boat. Bank: work inflows, dam walls, and points. Boat: broadside drift covering wind lanes.

Numbers are intensity 0 (none) to 3 (peak) — a guide, not a guarantee.
- Castilla y León licence + AREC permit required (Riaño AREC, Esla; permits via the Riaño tourist office or the regional federation)
- 25 cm minimum size, 5 trout/day
- Boat navigation needs the Confederación Hidrográfica del Duero registration
- Pike present is a non-native predator with its own handling rules.
A reasonable day here, though cloud isn't quite in the sweet spot.
Terrain map
- Wind conditions (ripple) closely match what this water fishes best in.
