EA surveys have recorded these fish at particular sites and times. Absence from a survey is not evidence that a species is absent from the river. Every valid individual length and weight is retained, with its sample size shown.
Useful context
This page follows survey locations along the main River Bollin. Tributaries and unrelated rivers with similar names are kept separate.
The map shows past fish records, not fishing access or a promise of what you’ll catch today.
