Stoneyford River

Stoneyford River — The River Boyne at Stoneyford, Co.Meath

A spring-fed Boyne tributary rising below Slieve na Caillaigh, which is the whole point of it — the springs keep the levels up through summer when other rivers are running thin, and the olive and sedge hatches are excellent for it.

About as good as it gets
River steady at a fishable height. On the feed top to bottom — start on the rises with a dry, drop a nymph if they stay down.

About this water

A spring-fed Boyne tributary rising below Slieve na Caillaigh, which is the whole point of it — the springs keep the levels up through summer when other rivers are running thin, and the olive and sedge hatches are excellent for it. Most of the trout are small wild fish with a stock of better ones among them, and they feed steadily right through the day, which is a rare and welcome thing. Fly-only catch-and-release from Stoneyford Bridge down to the Boyne. Stoneyford Angling Association; permits at Dempseys Maxol in Ballivor.

Hatches & food

A spring-fed limestone Boyne tributary whose steady summer flow and cool temperatures drive excellent, prolonged olive and sedge hatches — a genuine all-day dry-fly river with reliable Blue-Winged Olive into autumn.
