One of the key Mayo/Erris migratory systems where sea trout remain a real part of the fishery story, especially when runs and conditions align.

Atlantic Salmon fly box

Connemara/Mayo low water: a lightly-dressed shrimp on a floating line with sink tip, sized down from 8s in cold spring water to 12s and 14s as summer water warms and clears. Where the current runs faster, a slim tube or hairwing swung through tracks better than a shrimp.

About this water

Public IFI and Bangor Erris material still surfaces run-condition reporting for the Owenmore, and the broader Bangor Erris fishery narrative ties it together with Carrowmore Lake in a continuing salmon-and-sea-trout story. A large blanket-bog spate river on the Erris Peninsula with very fast response to rain — completely spate-dependent with tea-coloured peat water. Summer-running and weather-led, with fishability tied to water conditions and run timing rather than calendar certainty. Fish it on the drop after rain. Season 1 June to 30 September. For 2026 this remains an open fishery — salmon may be retained in season under the Wild Salmon & Sea Trout Tagging Scheme and bag limits, with catch-and-release at other times.

Hatches & food

EPA monitoring of the Owenmore (Erris)'s Mayo reaches confirms mayflies, stoneflies, caddis, aquatic diptera and gammarus are present. This is food-presence evidence from kick sampling only, not a record of emergence timing or a dependable hatch.
