I have only caught rainbows their all season: no browns, blues or tigers..
Boat or bank fishing? Best boat areas are the dam, cages, tower, hafod lom woods by the quarry. I have seen bank anglers in tower bay, by the dam & sailing club bay.
Fish were deep on daphnia last time - 25ft plus and caught on lures. But with the rain and cooler conditions dries and nymphs worth trying. Black is a very good colour there.
