Slow going — pick your moments
River temperature is the limiting factor today, not the flow. Fish dawn or dusk if you go at all, and handle everything with extra care.

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.

What would change the calculation
Cooler water — back toward the 10–16 °C ideal band — would lift the score and ease welfare.
The dawn and dusk windows score higher than the midday lull.
