About Cronfa Alwen
Cronfa Alwen, or Alwen Reservoir, is an unstocked Welsh Water reservoir near Cerrigydrudion, fished for fly and coarse species on a catch and release basis only. Beyond the wooden bridge at the north end only fly fishing is allowed, and elsewhere all legal coarse methods are permitted apart from live baiting.
A day ticket for 2026 is £16 and a season ticket £66, and both also cover Llyn Aled Isaf. The Llyn Brenig and Llyn Aled Uchaf season ticket covers Cronfa Alwen too. Permits come from the Llyn Brenig visitor centre or online. Welsh Water does not say which fish the reservoir holds.
Only one rod and line may be assembled, treble hooks are only for spinning, and ground bait, swim feeders, sweetcorn and maggots are not allowed. Every angler hands in a catch return after each visit. The position shown is approximate.
