How to fish it · for Trout
When
Late spring through early summer once the water warms; mornings and evenings in high summer. Trout open from late March under the Castilla y León order.
Where
Start with Parachute Mayfly (12-14) on a As per local method. Early in the day, nymphs and buzzers fished slowly tend to outperform attractors.
The plan
Plan A

Start with Parachute Mayfly (12-14) on a As per local method. Early in the day, nymphs and buzzers fished slowly tend to outperform attractors.

Plan B

A fry-imitating pattern stripped through the margins can save a blank in autumn.

Watch for

Keep an eye on changing conditions — wind shifts and cloud breaks can trigger short feeding spells.

Either bank or boat

Good ripple suits both bank and boat. Bank: work inflows, dam walls, and points. Boat: broadside drift covering wind lanes.
