About this water

The Ballinderry is a Lough Neagh tributary renowned for excellent wild brown trout fishing and autumn dollaghan runs. A mid-sized river with varied character — riffles, pools, and glides through agricultural country. Brown trout average 8–10 oz with fish to 2 lb throughout. Dollaghan enter from July and provide exciting autumn sport. Managed by local clubs with affordable day tickets.

Hatches & food

No venue-specific hatch data yet; as a spate river draining basalt and peat country, expect modest upwing and sedge activity typical of these lowland Ulster streams, topped up by terrestrial falls after summer rain — a general expectation, not an observed hatch.
