What fish are in the Beam?
Monitoring has recorded 20 species across 4 surveyed sites on this water, between 1996 and 2018. 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.
The passport shows identity, survey breadth, evidence freshness and trip constraints without turning unlike facts into an opaque “best river” score.
4 sites · 14 events
20 positive taxa aggregates are shown. More survey coverage is not a fishing-quality verdict.
