What fish are in the River Chelmer Upper (Main Reaches)?

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.
16 sites · 169 events
29 positive taxa aggregates are shown. More survey coverage is not a fishing-quality verdict.
