How to fish it · for Trout
When
April–July in line with the open period, with different tactics for margins, inflows, and headwater sections
Where
Start with Pheasant Tail Nymph (14–18) — on the point — slow figure-of-eight retrieve. If that does not produce, switch depth or speed before changing the pattern entirely.
The plan
Plan A

Start with Pheasant Tail Nymph (14–18) — on the point — slow figure-of-eight retrieve. If that does not produce, switch depth or speed before changing the pattern entirely.

Plan B

Slow down everything. A booby on a fast-sinking line, left static, can pick up deep fish.

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.

About this water

The Ebro headwaters and Embalse del Ebro in southern Cantabria offer open water in contrast to the steep coastal basins. Official rules show trout fishing here runs with its own exceptions — fishing every day in the open period and specific bag limits in the reservoir context. Less iconic than the Atlantic rivers but useful and real for a different kind of Cantabrian fly fishing. More open landscape, reservoir margins, and headwater streams.
