i was over working in ireland down county cork way, fished on the black water, wasnt fishing for anything but just showing a work mate how to cast a fly rod
but went to this lake which was recommended to me by a local tackle shop.

its the most beautiful lake ive ever set eyes on, not that ive been to many lakes but crystal clear water, lovely fish, plus its not just fishing there's other activities aswell on sight for the kids and holiday homes aswell. theres not much in the area but was a real nice place, i fished of the floating pontoons and had no trouble catching but you can only really fish one side
better hiring a boat
hope this helps
