About this water

Limburg river flowing from Germany and Belgium with some trout in the upper sections near the border. The Roer becomes increasingly coarse-fish territory downstream—validate local trout availability before planning. The Limburg section is the most interesting for fly fishing.

Seasons & zones
  • Trout 1 March → 30 September
  • Pike 31 May → 28 February

    Dutch national closed season for pike (snoek) is 1 March–last Saturday of May (release-only during that window) — correcting an earlier assumption of a Dec–Feb closure. No Roer/Limburg-specific exception was found. The close date shifts yearly (last Saturday of May); '31 May' reflects 2026 and will need updating in years where that Saturday falls later.
