Lough Derg Angling

Lough Derg Angling

Lough Derg is a great location for the angler, there are huge shoals of bream, roach, hybrids, tench and pike. The most popular spots are around the waters of Portumna, Mountshannon and Garrykennedy. Portumna is especially noted for large weights of bream and attracts anglers from all over the world.

Lough Derg is a large lake of over 30 kilometres in length and is regarded as a mixed fishery. Lake brown trout indigenous to Lough Derg and are well distributed throughout the lake.

While the season opens in March, the height of the angling year is undoubtedly during the Mayfly season. Fish feed ferociously on mayfly and are in prime condition as they leave the lake on their migratory journey up river to their spawning grounds on the Little Brosna/Camcor rivers and other tributaries on the system. Artificial local patterns of the Greenfly and the Spent Gnat Mayfly are fished dry on 6lb line during the Mayfly season which commences in late April/early May. Another popular method is to Dapp the live Mayfly itself or a Golden Olive fished wet to represent the emerging mayfly.

Trolling Rapalas is practiced early in the year with some success. Some very large fish can be caught such as that in the picture featured above.
