How to fish it · for Atlantic Salmon
When
Spring from March; grilse from June; main run through summer. Delphi is rapid-response spate water — fish the rise and the drop after rain. Late afternoon often the prime window.
Where
Delphi Lodge beats through the Bundorragha River and the loughs. Heads and tails of named pools; the lodge ghillies will direct you.
Method
Small doubles 10 to 12 across-and-down on a floating line; small tubes on a sink-tip in spring water. Catch-and-release encouraged across most Irish salmon water.
Kit
10 ft #7 single-hander on the smaller spate rivers; 11 ft switch where the river opens out. Floating line plus light sink-tip. 10 to 12 lb fluoro tippet.
Why this works
Water at 18.8°C — above the atlantic salmon caution line (18°C). Fish dawn or dusk only. Land it fast, wet hands, no air shots.

Permits & access
Permit required — see local rules.
- Private fishery — book through Delphi Lodge; premium pricing
- To protect the genetic integrity of the wild stock, all fish of hatchery origin ('ranchers', recognised by a clipped adipose fin) must be killed and gill-tagged under State licence
- Wild salmon must be released — with one exception: an angler's first-ever salmon may be kept
- All sea trout are catch-and-release (and under regional bye-law it is in any case an offence to kill a sea trout over 40 cm in the Galway, Connemara and Ballinakill districts)
- Wading prohibited on all beats — fish from the bank; lifejackets required on the loughs

Sea trout: Variable seasonal (2026) — Delphi (Co. Mayo) — exclusive Connemara spate fishery in the Doolough valley. Sea-trout runs present recent recovery signals but operate within the broader 1990s-onwards Connemara context. Catch-and-release is the norm.
