About this water

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.
