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 here are a non-native invasive. High summer fishes poorly, and where catch-and-release is legal warm-water release mortality is high; elsewhere the official advice is to remove any pike caught from the water rather than return it. Defer until water cools below 19°C.
Where
Water at 34.7°C — too warm to target pike today: poor sport, and where catch-and-release is legal (designated pre-2007 waters) warm water makes released fish die. Where it isn't, the official advice is to remove any fish caught from the water rather than return it. Either way, wait for cooler water.
The plan
Plan A

Water at 34.7°C — too warm to target pike today: poor sport, and where catch-and-release is legal (designated pre-2007 waters) warm water makes released fish die. Where it isn't, the official advice is to remove any fish caught from the water rather than return it. Either way, wait for cooler water.

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.

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

A close-in supply reservoir 40–55 minutes west of Madrid on the Aulencia / Guadarrama drainage. Not a classic fly venue, but on the right day it fishes well for carp, barbel, and pike. Sight-fishing the margins for cruising carp is the most rewarding fly proposition; pike will take streamers in the cooler months. Trout logic doesn't apply here — read visibility, wind, water temperature, and recent pressure instead.

Why this score
  • Cloud cover (cloud) suits the fishery well.
  • High temperatures may push fish deeper and reduce surface activity.
