The river Nenagh flows into Lough Derg at Dromineer, and is a major trout fishery with trout of up to 2lb in the wider stretches. Angling in the river is controlled by Ormond Angling Association, and a permit can be obtained at Whelans in Nenagh.
Dromineer provides some of the best angling in mid Lough Derg, with trout of up to 10lb caught and also good for dry fly and dapping. Some of the best coarse fishing in the area can be had at Youghal Bay.
