We have not characterised this dam's release, so this is a general cold-release figure and could be several degrees out in either direction. Treat it as a hint, not a reading, and check locally before you fish.
How to fish it · for Barbel
When
Summer through autumn — June through September prime. The lower Tormes barbel are bigger on the Villagonzalo beats than on the Santa Teresa stretches.
Where
Deeper runs and slower glides through the Villagonzalo II beat. Barbel hold below the trout water in summer warm.
Method
Weighted nymphs upstream — Spanish-style heavy nymphing through the deeper runs. San Juan worm patterns and large weighted caddis pupa take well; strike on the slightest pause.
Kit
10 ft #4 nymphing rod with a heavy weighted point fly; 5 to 6 lb fluoro tippet. Studded boots — barbel water runs deeper and slicker than the trout reaches.
Why this works
Good — water clarity is working for you, but water temperature is the limiting factor today.
Likely species
Mayflies
Damselflies & dragonflies

- Se requiere licencia de pesca de Castilla y León más el permiso específico del coto Villagonzalo II
- La Junta identifica este como el único coto legal de hucho en España
- Las normas pueden diferir de los cotos de trucha adyacentes — verifica la orden anual
- Se aplican normas de conservación; la población de hucho se mantiene mediante sueltas gestionadas.

What would change the calculation
Warmer water — toward the 16–24 °C ideal band — would lift the temperature score.
The dawn and dusk windows score higher than the midday lull.
Directions
Seasons & zones
- Barbel 1 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.
