Embalse de Tanes

Embalse de Trasona terrain map
Terrain map

Tanes sits in the Redes country, a steep green reservoir on the upper Nalón that also waters Oviedo and Gijón — so nobody is launching a boat here.

Species

A patient day, if you fancy it

Glassy and bright — hard work without a breeze. A flat lough is a quiet lough — wait for the breeze.

How to fish it · for brown trout
When
Late spring to summer; note the left-margin closure below Coballes bridge until 15 June.
Where
With limited drift, anchor or fish static from sheltered positions. Work a bushy searching pattern on the bob and drop a contrasting nymph on the point. In the calm, a single dry fly or a slowly-fished nymph tends to out-fish an active retrieve.
The plan
Plan A

With limited drift, anchor or fish static from sheltered positions. Work a bushy searching pattern on the bob and drop a contrasting nymph on the point. In the calm, a single dry fly or a slowly-fished nymph tends to out-fish an active retrieve.

Plan B

If the main plan is not working, switch to a smaller, more imitative pattern fished slower and deeper. A change of drift angle can also make a difference.

Watch for

Evening tends to be the best period in summer — stay late if you can for a sedge or spinner fall.

Bank

Flat calm suits bank fishing near features — points, weed beds, and inflows where fish patrol.

Why this score
  • summer conditions with overcast skies and calm wind.
  • Reservoir at or above capacity, likely spilling — fish congregated at the outflow.

About this water

Tanes sits in the Redes country, a steep green reservoir on the upper Nalón that also waters Oviedo and Gijón — so nobody is launching a boat here. That leaves the bank, and the bank fishes better than the gradient suggests. The brown trout are wild and the setting is the Parque Natural de Redes, which means you fish among beech woods and the occasional incurious deer. There is a wrinkle worth knowing: the left margin below the Coballes bridge stays shut until the middle of June, so check the line before you commit a morning to it. Six trout is the daily limit, though sense and the no-kill habit both argue for fewer. A quiet, scenic, properly Asturian bit of water.
