Description

Cantref  Reservoir is a FLY ONLY water holding a small amount of introduced Rainbow Trout and a natural head of Brown Trout. It is one of three reservoirs that were built in the early 1900’s to supply the City of Cardiff with water. It had a good reputation as a wild brown trout fishery until the demand for fishing saw it being turned into a stocked Rainbow fishery.

The Alliance has now reversed this with minimal stocking of Rainbow trout seeing an increase of the native brown trout once again.

The Reservoir is open all year round for fishing for Rainbow Trout.  The season for Brown Trout is 20th March until 17th October.  Please return any Brown Trout to the water.  Please use barbless hooks or hooks with the barbs crushed.

Flies for brown trout:  All the usual small black ones that go on our mountain lakes and the ones you used to catch fish on when fishing Welsh Mountain Lakes : Dawl Bach, Black and Peacock, Bibio, Zulu, Black Buzzers, Awl  as well as the Silver Invicta, Mallard and Claret and most of the reservoir flies that you would tend to use in Wales.
