How to fish it · for Trout

The plan
Plan A

Start with Pale Yellow Emerger (18-22) 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.

Bank, sheltered shores

Strong wind makes boat fishing difficult — sheltered bank spots near lee shores will fish best.

About this water

A small urban reservoir near Avilés, formerly managed as a coto intensivo for put-and-take rainbow trout. Since COVID, the stocking programme has not been clearly reinstated and local reports suggest the fishery has shifted toward carp-dominated coarse fishing with occasional brown trout. Official documentation from the Principado covers permits and seasonal adjustments but does not describe any current intensive trout stocking. The reservoir still functions as a fishing venue, but fly anglers specifically targeting trout should manage expectations and check recent reports before travelling.

  • Mixed
Why this score
  • Wind conditions (strong) are not ideal for this water.
  • Temperature (moderate) is in the sweet spot for autumn fishing.
  • Terrestrials are in their seasonal window, boosting the chance of targeted feeding.
