I fish a small river which has a flow. The flow can change quite considerably as the lock gates are opened. Which groundbait would you recommend and why?
The answer very much depends on the depth and the species present. I'd suggest you try a slightly heavier groundbait than normal such as Van den Eynde Super Roach, which is somewhat sticky. If necessary you could add some damp leam to ensure the groudbait stays down.
