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.

Reasonable autumn fishing likely at Embalse de Tanes
Water temperature is the limiting factor today, not the wave. Fish dawn or dusk if you go at all, and handle everything with extra care.
56% confidence

Seasonally this is the right time to be here, but today's conditions are not doing Embalse de Tanes many favours. It can still fish, but temper expectations.

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 Foam Beetle (14-18) 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 Foam Beetle (14-18) on a As per local method. If that does not produce, switch depth or speed before changing the pattern entirely.

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.

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.
