About this water

Armagh, holding wild brown trout and a run of dollaghan — the migratory Lough Neagh brown trout — from late summer. Drumlin-country water best fished on a settling flood.

Hatches & food

No venue-specific hatch data yet; as a lowland main-stem river, expect the steadier upwing, sedge and midge activity typical of Ulster lowland rivers rather than a documented hatch — general guidance only.
