Len fishing evidence · Kent, South London and East Sussex

What fish are in the Len?

Monitoring has recorded 21 species across 7 surveyed sites on this water, between 2002 and 2023. These are survey records with dates. They do not establish what is present today, that the water is fishable, or that you have permission to fish it.

River evidence passport

Four signals, kept deliberately separate.
