With limited drift, anchor or fish static from sheltered positions. Work a bushy searching pattern on the bob and drop a contrasting nymph on the point. In the calm, a single dry fly or a slowly-fished nymph tends to out-fish an active retrieve.

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.

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

Calm evenings can fish well from bank or boat — target rising fish wherever you find them.
