Embalse de Tanes

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.

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

How to fish it · for Trout
When
Late spring to summer; note the left-margin closure below Coballes bridge until 15 June.
Where
Start with CDC F-Fly (Black) (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 CDC F-Fly (Black) (18-22) on a As per local method. If that does not produce, switch depth or speed before changing the pattern entirely.

Plan B

Fish early and late, try deeper during the heat of the day with a fast-sinking line.

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.

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.
