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 21.7°C. This is the line where catch-and-release kills pike. Do not fish for them today.
The plan
Plan A

Water at 21.7°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.

Bank

Bank-only venue. Fish from accessible margins, points, weed edges, and inflows.

About this water

A 120-acre reservoir near Colchester with a genuine specimen pedigree — carp to over 40 lb and pike to over 25 lb, alongside a mixed head of match species. Formerly a trout fishery, now run by Anglian Water for coarse and predator angling. The size of the fish rather than the number of bites is the draw, and sessions are long ones. Day and season permits; under-18s fish free.
