The River Blackwater and many of its tributaries hold good numbers of brown trout, although they tend to be on the small side, averaging 6 to 10 inches (15 to 25 cm) in length, with bigger fish being encountered occasionally. They rise freely especially in the late evening, and the best of the fishing is in May and June, using small wet flies, or dry Olives and Sedge patterns.
Trout fishing is mainly controlled by local village clubs, which often use, at the discretion of their owners, various salmon beats on the understanding that salmon anglers have priority over the fishing and water. Permits to fish for trout can usually be obtained through tackle shops local to where you are staying.
The Rivers Suir, Nire and Tar are also within range, and can boast excellent trout fishing, with some very big wild fish caught each year. Permits to fish and Information on these rivers, can be obtained from Clonanav Fly Fishing, Ballymacarbry, Clonmel, Co. Waterford.
There are also opportunities to fish a limited number of stocked still water venues for trout both brown and rainbow. Waterford City and County Trout Anglers Association control three very natural Resevoirs, Knockaderry, Carrigavantry, and Ballyscanlon. Permits and details available from the Centra Supermarket in Kilmeaden, boat and bank fishing is available.
Ballyhass Lakes near Mallow also provide stocked rainbow trout fishing, from the bank or from boats, with some good fish caught.
Sea trout are sometimes encountered on the River Backwater, mainly in the lower beats but also in the River Bride (the Blackwater's main tributary), but again tend to be on the small side, although a fish of nearly 8 lbs was recorded recently from the Blackwater itself. Again, you can obtain permits to fish for sea trout through tackle shops local to where you are staying.
