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 ambush-feeding from weed cover. Fry and small perch concentrate in the warm shallows, drawing pike in during low-light periods. Mid-day pike retreat to deeper weed channels.
Where
Summer pike on the fly. Fish early (first light) and late (last hour) when pike push shallow to feed. Topwater is king — poppers and gurglers over weed beds. Mid-day fish hold deep in weed channels. Take a break during the heat of the day. Use a 9-10wt rod with a stiff butt for turning big fish away from weed. Welfare note: Water at 19.5°C — warm for pike. Fish dawn or dusk only. As a non-native invasive, handle by local rules: return one only where catch-and-release is legally permitted; elsewhere the official advice is to remove it from the water rather than return it.
The plan
Plan A

Summer pike on the fly. Fish early (first light) and late (last hour) when pike push shallow to feed. Topwater is king — poppers and gurglers over weed beds. Mid-day fish hold deep in weed channels. Take a break during the heat of the day. Use a 9-10wt rod with a stiff butt for turning big fish away from weed. Welfare note: Water at 19.5°C — warm for pike. Fish dawn or dusk only. As a non-native invasive, handle by local rules: return one only where catch-and-release is legally permitted; elsewhere the official advice is to remove it from the water rather than return it.

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

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.
