How to fish it · for Trout
When
Conditions are not ideal but fishable at Embalse de La Granda. The ripple should help fish move and feed more confidently. Very warm conditions — trout have a narrower safe zone of cool, oxygen-rich water. Fish only at first light or last light, use barbless hooks, keep fish in the water during release, and stop if fish struggle to recover.
Where
Start with Damsel Nymph (12-14) on a slow figure-of-eight or hang under indicator. Midday in warm weather — try deeper water or switch to a sinking line. When no hatch is visible, a buzzer team — black stripped quill on the point, attractor or pearl-rib on the top dropper — is the default starting point on any UK stillwater.
The plan
Plan A

Start with Damsel Nymph (12-14) on a slow figure-of-eight or hang under indicator. Midday in warm weather — try deeper water or switch to a sinking line. When no hatch is visible, a buzzer team — black stripped quill on the point, attractor or pearl-rib on the top dropper — is the default starting point on any UK stillwater.

Plan B

Fish early and late, try deeper during the heat of the day with a fast-sinking line.

Watch for

Evening tends to be the best period in summer — stay late if you can for a sedge or spinner fall.

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

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.
