Castleconnell is one of the most prestigious salmon fisheries in Ireland, set on the lower River Shannon just 11 kilometres upstream of Limerick City and tidal water. Managed by the Electricity Supply Board, this 7.2-kilometre fishery is divided into six beats of roughly 800 metres each, with each beat allowing four rods and containing up to six or more individually distinct pools.
The Shannon at Castleconnell was historically famous for enormous spring salmon — Augustus Grimble recorded fish up to 45lb and beat averages of 21lb in 1913. Today's spring fish are more modest, averaging 10-12lb, but the fishery's reputation endures. The early spring run from mid-March brings the first fish, followed by the locally renowned 'April fliers' through April and May. The peak of the season coincides with the main grilse run from mid-May through July. August tends to be quiet before some renewed activity in September with autumn fish.
Water levels at Castleconnell are controlled by the ESB at the Ardnacrusha Hydro Electric Dam, five kilometres upstream. This provides stable flows even in drought conditions and distinguishes the fishery from spate-dependent rivers. Fly fishing is the primary method, with a 14ft double-handed rod recommended for covering the pools. Bank fishing using the provided angling platforms is the norm, though chest waders are advantageous on some beats, particularly Beat 8 at the top of the fishery.
The setting is exceptional. The riverbanks are lined with mature ash, beech, and oak trees, with swans, otters, and kingfishers present. The village of Castleconnell itself is a quiet, attractive settlement with accommodation, dining, and the Castle Oaks House Hotel overlooking the fishery.
Downstream of the salmon beats, the Shannon transitions to deeper, slower water with excellent coarse fishing for bream, roach, and hybrids, plus quality pike fishing. This makes Castleconnell a viable destination for mixed-species anglers.
Castleconnell is approximately 11km north of Limerick City on the R503. Shannon Airport is about 35km away (45 minutes). Angling platforms using local stone and materials are provided on the fishery for bank fishing access to the pools. Most beats are fishable from the bank using a conventional fly rod. Chest waders are recommended on Beat 8 (the top beat) and are generally advantageous throughout. A public car park is located upstream of Beat 1, with access to Woralls End via Castleconnell village.
Signature features
ESB-Controlled Water Levels
Unlike spate-dependent rivers where anglers wait for rain, water levels at Castleconnell are regulated by the ESB at Ardnacrusha dam. This provides stable, fishable conditions even in drought, making the fishery more reliable than many Irish salmon rivers.
Six Distinct Beats
The fishery is divided into six beats of approximately 800 metres, each with up to six or more individually distinct pools. No two pools fish the same way, providing variety across a day's fishing. Four rods are permitted per beat, ensuring the fishery never feels crowded.
Season by season
March – May (Spring Salmon)
The fishery opens March 1. A sprinkling of spring salmon arrive through March. April and May bring the 'April fliers' — a good run of fish averaging 10-12lb. This is an important spring fishery that can produce up to 200 spring salmon in a good year. Heavily dressed flies in sizes 4-8.
Mid-May – July (Grilse)
The peak of the Castleconnell season. The main grilse run arrives from mid-May and continues through June and into July. The fishery's worldwide reputation for grilse fly fishing is well deserved. Smaller fly sizes (6-10) are effective.
August – September (Late Season)
August tends to be quiet with fewer fish moving. September can see renewed activity as autumn fish pass through. Fresh fish continue to move from the estuary with rises in water level. Worthwhile fishing in suitable conditions right up to the September 30 closing date.

Seasonal fly & tactics guide
Spring (March – May)
Patterns
Black GoldfinchSilver DoctorHairy MaryGarry DogMephisto
A 14ft double-handed rod covers most pools comfortably. Spring flies are heavily dressed in sizes 4-8. Fish the pools methodically, working downstream. The ESB-controlled water levels mean consistent flows regardless of rainfall. Early in the season, larger flies and deeper presentations are often required.
⚠️Common mistake: Fishing too fine in spring. The Shannon is a big river and the spring fish are strong — use a rod and line weight that can handle them in the current.
Grilse (Mid-May – July)
Patterns
Hairy MarySilver DoctorBlack Goldfinch
The grilse run is the peak period. Smaller flies in sizes 6-10 are effective. A single-handed grilse rod is adequate on some beats, though the double-hander gives better pool coverage. Fish are typically more willing than spring salmon, and multiple-fish days are possible in good conditions.
⚠️Common mistake: Ignoring the less famous pools. Every beat has its character and even the quieter pools hold fish during the main run.
