River temperature is the limiting factor today, not the flow. Fish the cool of dawn or dusk, land fish fast, and stop if one struggles to recover.

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
  • Source: delphilodge.ie.

About this water

One of Ireland's most celebrated private fisheries sits in the Doolough valley — a conservation-led operation. Two loughs, Doolough and Finlough, feed the short Bundorragha river that runs to Killary Harbour, Ireland's only true fjord. Most salmon are taken in the brief river; some in Finlough, rarely in Doolough. The setting is as important as the fishing — wild and beautiful in a way that stays with you. A small spring run of multi-sea-winter salmon from April; grilse-dominated from June onwards. Very fast spate response — fishable windows are brief after rain. Fish the pools systematically with tube flies, taking advantage of the quick rise and drop. Delphi's rule protects the wild gene pool: any fish of hatchery origin ('ranchers', recognised by a clipped adipose fin) must be killed, while wild salmon are released — with the single exception of an angler's first-ever salmon, which may be kept. All sea trout are catch-and-release.

Hatches & food

EPA kick-sample monitoring of the Bundorragha system at Delphi (2009-2018) confirms mayflies, stoneflies, caddis, midges and blackflies, craneflies, and freshwater shrimp (Gammarus) are all present in the aquatic food base. This is presence evidence from monitored waterbody segments only, not a record of emergence timing, abundance, or a visible hatch on the water.

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.
