A patient day, if you fancy it
Water temperature is the limiting factor today, not the wave. Fish dawn or dusk if you go at all, and handle everything with extra care.

How to fish it · for Trout
When
The terrestrials are on.
Where
Work a bushy searching pattern on the bob and drop a contrasting nymph on the point.
The plan
Plan A

Work a bushy searching pattern on the bob and drop a contrasting nymph on the point.

Plan B

If the main plan is not working, switch to a smaller, more imitative pattern fished slower and deeper. A change of drift angle can also make a difference.

Watch for

Keep an eye on changing conditions — wind shifts and cloud breaks can trigger short feeding spells.

Boat — at anchor

Windy conditions suit anchoring in productive areas rather than open-water drifting.

About this water

Classic accessible stillwater fly fishing: chironomids, leeches and damsels for hard-fighting trophy trout.
