Monitoring has recorded 16 species across 13 surveyed sites on this water, between 2004 and 2019. 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.

Permission is not established
Survey evidence carries no access boundary, permit, opening status, catch forecast or live safety signal. Resolve each before travelling.
Ordered by how many sites on this water recorded the species. A species not listed has not been recorded by these surveys — which is not the same as being absent.
