San Juan Worm

Bottom worm pattern
Carp · Barbel · Trout · GraylingSubsurface

A simple, highly effective worm imitation for bottom-grubbing fish. Carp and barbel eat worms confidently, especially after rain or when margins are disturbed.

Fish this when

Coloured water, after rain, soft margins, fish feeding hard on the bottom. Red is the workhorse colour; pink works in slightly stained water.

Why it works

Carp and barbel encounter worms naturally when rain washes them in. A segmented, flexible profile drifting along the bottom needs no explanation.
