About this water

The banks are high in places, but there is plenty of fishable water and a sound stock of wild brown trout from half a pound to a pound and a half — the kind of unfussy river you can spend a whole evening on without meeting another soul. Longwood Angling Association controls the water below Johnstown Bridge and runs it catch-and-release.

Hatches & food

A limestone Boyne tributary with steady wild-trout fly life — reliable olives through spring and autumn, summer Blue-Winged Olive and evening sedge, plus black gnat falls on warm afternoons.
