Not the day for it
River dropping into shape after a lift. Not much stacked in your favour today. Worth an hour if you are nearby, not worth the special trip.

About this water

A Comeragh-mountain spate tributary of the Suir near Ballymacarbry, running off old red sandstone with small, wild, free-rising brown trout. A flood river — fish it on a dropping spate; the Nire valley is also a noted fly-fishing base.

Hatches & food

EPA freshwater monitoring on the River Nire confirms mayflies, stoneflies, caddis, aquatic diptera and freshwater crustaceans (including white-clawed crayfish) are present. This is food-presence evidence from kick sampling, not a confirmed hatch or rise pattern.
