Owenglin River

The Owenglin runs off the Twelve Bens through Clifden to the sea — a classic Connemara granite spate river, open for 2026 as a brown-tag fishery.

Stop — too hot for atlantic salmonThe water is at the line where atlantic salmon die after release. Rest the river today.

Water measured at 21.1°C from the nearest gauge. This is at or above 20°C — the temperature at which catch-and-release kills atlantic salmon. A fish that swims off can be dead hours later from the strain. Rest the river for atlantic salmon until the water drops below 18°C. Overnight cooling helps. Shaded headwaters and cold tributary mouths may hold cooler. Other species here may be unaffected — check the tabs.

DepthOnly the cold places hold safe fish: spring inflows, deep shaded pools, cold tributary mouths. Even fish lying there are working hard.
TimingDo not target atlantic salmon until the water is back below 18°C. Dawn is the coolest hour — check before you decide.

About this water

The Owenglin runs off the Twelve Bens through Clifden to the sea — a classic Connemara granite spate river, open for 2026 as a brown-tag fishery. Salmon enter from February; grilse and sea trout follow in summer. As with all these mountain rivers, it is the flood that brings the fish, and fishing it low is rarely worth the walk. Clifden and Connemara permits; the Salmon and Sea Trout State Licence is required.
