This is peak season for Embalse de El Atazar, though today's conditions aren't quite ideal. Worth fishing — the timing is right even if the weather isn't perfect.

Head to
Wind driftNW wind
South-eastern end

A northwesterly has held for 11 hours, running warmer than the water (14°C air against 7°C water). Expect fish at the south-eastern 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 Pike
When
Pike are feeding aggressively as water cools, building reserves for winter. Weed is dying back, concentrating both pike and prey fish into predictable holding areas.
Where
Autumn/winter pike on the fly — big fish season. Pike are putting on condition and take large flies confidently. Fish dropping weed edges, deep channels, and structure. Start with a sinking line and move to faster-sinking as the water cools. Biggest pike of the year come in this window.
The plan
Plan A

Autumn/winter pike on the fly — big fish season. Pike are putting on condition and take large flies confidently. Fish dropping weed edges, deep channels, and structure. Start with a sinking line and move to faster-sinking as the water cools. Biggest pike of the year come in this window.

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.

Either bank or boat

Good ripple suits both bank and boat. Bank: work inflows, dam walls, and points. Boat: broadside drift covering wind lanes.

Ranked for today
Pike fly box

Probably the best pike fly fishing window of the year. Cooling water activates pike metabolism and baitfish shoal up before winter, concentrating the predators. Fish are aggressive feeders moving to windward banks, dropoffs, and points where baitfish are pushed. Large profile baitfish streamers on intermediate lines retrieved at medium pace, with pauses at structure edges. Count-down retrieves to find the active depth. Fish move — cover ground rather than working one spot.

About this water

Madrid's largest reservoir, on the lower Lozoya system 70–90 minutes north-east of the city. Big, scenic, serious water that is not easy to read — bank access varies by water level and the steep walled arms mean covering water is a real exercise. Holds black bass, pike, carp, and barbel. For the fly angler this is an exploratory day, not a beginner trout substitute: lower catch certainty but genuine potential for the angler willing to walk and search.
