Know your rivers - salmon and sea trout catchment summaries

Our reports describe the status of the salmon and sea trout populations for each of the principal salmon and sea trout catchments in Wales

Vyrnwy - Plas Dolanog

They bring together data from rod catches, stock assessments and juvenile monitoring; describing the factors limiting the populations and setting out the challenges faced in the catchments.

Habitat improvements to restore freshwater productivity of salmon and sea trout populations are set out in action tables. These tables include joint projects in which work will be carried out by our partner organisations, not just Natural Resources Wales (NRW).
