Seasonally this is the right time to be here, but today's conditions are not doing Embalse de San Juan many favours. It can still fish, but temper expectations.

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

A general southern European warmwater fly pack for barbel, carp and mixed exploratory venues built around slower rivers, canals, backwaters and marginal sight-fishing opportunities. Weighted nymphs, buggy worm patterns, crayfish flies and compact baitfish or leech-style flies matter more than surface trout logic.

About this water

Reservoir on the Río Alberche immediately upstream of Picadas, 70–90 minutes west of Madrid. A leisure water — boats, sailing, swimming — that nevertheless holds a real multi-species fishery: black bass, carp, barbel, pike, and zander. Bank fly fishing is most productive away from the busy leisure shore; the upper arms where the Alberche enters fish better than the dam end. Pre-spawn bass (April–June) and autumn pike are the strongest fly windows.
