How to fish it · for Trout
When
Conditions are not ideal but fishable at Embalse de Trasona. The ripple should help fish move and feed more confidently. As the heat eases this evening, fish may move up in the water column.
Where
Start with Pale Yellow Emerger (18–22) on a As per local method. If that does not produce, switch depth or speed before changing the pattern entirely.
The plan
Plan A

Start with Pale Yellow Emerger (18–22) on a As per local method. 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

Like the other city-adjacent intensivos (San Andrés, La Granda), there is no clear evidence of current trout stocking. The 2016 critique of salmonid management in Asturias noted that restocking programmes were often poorly managed, and the pattern since COVID has been one of quiet decline rather than intentional phase-out. What remains is a mixed coarse fishery dominated by carp with occasional brown trout. For a genuinely stocked Asturian stillwater, El Arenero at Tineo is the realistic option.
