Head to
Wind driftE wind
Western end

An easterly has held for 18 hours, running warmer than the water (14°C air against 12°C water). Expect fish at the western end — the bank it is blowing into — where the drift piles food, colour and warmth together. This reads the upper water, though — a bottom bait at range feels it far less than a floater or a fish in the margins. Treat it as a tiebreaker between good swims rather than an override — features and angling pressure usually count for more.

How to fish it · for Trout
When
Conditions are not ideal but fishable at Embalse de La Granda. Warmer water may push fish deeper — try sinking lines or deeper nymphing.
Where
Start with Pale Yellow Emerger (18–22) on a As per local method. Early in the day, nymphs and buzzers fished slowly tend to outperform attractors.
The plan
Plan A

Start with Pale Yellow Emerger (18–22) on a As per local method. Early in the day, nymphs and buzzers fished slowly tend to outperform attractors.

Plan B

Slow down everything. A booby on a fast-sinking line, left static, can pick up deep fish.

Watch for

Keep an eye on changing conditions — wind shifts and cloud breaks can trigger short feeding spells.

Bank, sheltered shores

In wind, bank fish the lee shore — boats can anchor in productive areas if conditions allow.

About this water

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.
