Not the day for it
Good wave on — drift country. Not much stacked in your favour today. Worth an hour if you are nearby, not worth the special trip.

How to fish it · for pike
When
Pike are under severe thermal stress. Post-release mortality is high. Defer the session until water cools below 19°C.
Where
Water at 34.8°C. This is the line where catch-and-release kills pike. Do not fish for them today.
The plan
Plan A

Water at 34.8°C. This is the line where catch-and-release kills pike. Do not fish for them today.

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

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.
