How to fish it · for brown trout
When
Through the Castilla y León trout season — opens 3rd Sunday of March, closes 31 July. Spring olives April through May; summer sedges in evening hours; sin muerte stretches extend through autumn.
Where
Santa Teresa trout beats below the reservoir; cooler reservoir releases keep fish moving into the warm months. Pool tails, riffle heads, and the seams behind boulders.
Method
Upstream dry to risers; dry-dropper through the riffles. The Tormes runs clear granite water — long leader, fine tippet, careful approach.
Kit
9 ft #4 — Spanish granite spate default. Floating line, 12 ft leader to 4 lb fluoro. Studded boots — granite cobble runs slick.
Why this works
Excellent — water temperature is working for you, but time of day is the limiting factor today.

About this water

The stretch below the Santa Teresa reservoir is where the modern Tormes reputation lives. The Junta de Castilla y León describes this as one of the best trout-water sections in Salamanca province — water where trucha común lives and reproduces, not just stocked put-and-take. The managed beats are El Chorrón, Tormes, Galisancho, Tormes I, and Alba de Tormes — collectively covering over 27 km of access-improved river. Below these trout beats, the Villagonzalo II coto holds Spain's only legal hucho fishery (see separate entry). This is a bigger, more fertile, regulated river than the upper Tormes — think tailwater character with steady flows, depth changes, and fish that respond to methodical, structure-oriented fishing rather than romantic dry-fly covering of pretty pocket water.

  • Barbel1 January → 31 December

    Barbel is fishable year-round in Castilla y León's aguas libres, but a mandatory catch-and-release (zero-kill) window applies 1 May–15 July each year to protect spawning — anglers must release all barbel caught in that period (Orden MAV/1506/2025). This is a harvest rule, not a closure, so the season stays open throughout the year.
