About this water

Estuarine sea trout fishery where fish move on tides and runs. Season 1 March to 30 September. Fish the tidal flows as sea trout push upriver. The River Erne itself never had a significant run — this is an estuary-specific fishery. A unique opportunity for tidal fishing in northern Ireland waters.
