About this Water

The River Moy flows through County Mayo in Ireland's west, emptying into Killala Bay after passing through Ballina — a town whose entire identity is built around Atlantic salmon. The Moy is consistently one of Ireland's most productive salmon rivers, with the famous Ridge Pool at Ballina capable of holding hundreds of visible fish on the right tide. Grilse arrive from June onward, with the finest autumn fish running September through October. The Moy's classic wet fly tradition is one of the oldest in Atlantic salmon culture.

The Ridge Pool at Ballina is one of the most extraordinary salmon pools in the world — standing on the bridge at certain tides, you can count dozens of silver Atlantic salmon resting in the clear water directly below.

Recommended Flies — Atlantic Salmon (Salmo salar)

The River Moy in County Mayo is Ireland's most productive Atlantic salmon river. The famous Ridge Pool in Ballina has produced more salmon than any comparable stretch in Ireland. Spring fish (April–June) are large and chrome; summer grilse (July–August) arrive in numbers. The Moy system includes excellent tributaries.

Productive Patterns

Technique

The Ridge Pool in Ballina is famous worldwide — fish can be seen stacked there in summer. Book the state-owned Ridge Pool beats through the Moy Fisheries. Single-handed or light Spey rods for the medium-sized river. Traditional wet fly techniques on the swing. Irish ghillies provide excellent guidance.

Seasonal Notes

Spring salmon enter from February. Grilse runs peak in June–August. Autumn fish arrive September–October. Dry fly (Bomber, Wulff) can be effective in low warm water for grilse — the most exciting Atlantic salmon fishing.

January Outlook

January — the River Moy in County Mayo, Ireland is in winter rest. The Atlantic salmon and sea trout are at sea. The River Moy system — which drains Lough Conn and the extensive Mayo catchment — flows cold through Ballina under winter skies.
