Lough Sheelin

View across Lough Sheelin towards the Derrysheridan shoreline, broad open water with the far shore.

A Midlands limestone lake with a long memory of specimen brown trout, and fighting fish rather than easy ones.

Head to
Wind driftW wind
Western end

A westerly has held for 8 hours, running colder than the water (8°C air against 11°C water). The end it blows into is taking that chilled surface water, so try the sheltered western end instead — off the back of the wind, where the undertow returns food along the bottom. That chill sits in the top of the water, though, and the bed is slower to feel it — on a bottom bait it is the undertow, not the temperature, that puts you at this end. Treat it as a tiebreaker between good swims rather than an override — features and angling pressure usually count for more.

How to fish it · for Trout
When
Late May to early June (mayfly peak); buzzer fishing March–April is the local specialist technique
Where
Set up a broadside drift and cover the water systematically. Work Muddler Minnow on the bob and Perch Fry on the point.
The plan
Plan A

Set up a broadside drift and cover the water systematically. Work Muddler Minnow on the bob and Perch Fry on the point.

Plan B

If the main plan is not working, switch to a smaller, more imitative pattern fished slower and deeper. A change of drift angle can also make a difference.

Watch for

Keep an eye on changing conditions — wind shifts and cloud breaks can trigger short feeding spells.

Boat — drift

A gentle ripple is ideal for drifting — broadside drift covering the wind lanes should be productive.

About this water

A Midlands limestone lake with a long memory of specimen brown trout, and fighting fish rather than easy ones. Sheelin went through lean years when pollution compromised it, and the recovery since has been the real story here — worth knowing before writing the place off on an old reputation. Mayfly from the middle of May fishes well, and the lough is at its best from late April through June, when olives and mayfly between them carry the season. Good boat fishing whenever the breeze cooperates.

Hatches & food

Duckfly opens the season, running from around 15 April and peaking about the 25th into early May across the productive bays and shore drifts; a spring lake-olive hatch can start as early as April and typically peaks in early May, from Rusheen Bay through Derrahorn. Large mayfly usually gets going with first flies between 7 and 12 May, fishing well by day and evening into early June, and Caenis hatch heavily through June and July with the best sport typically found 05:00-07:30 in calm, mild conditions. Sedges, including the Green Peter and Murrough among them, build from mid-June and continue into autumn, though timing that late in the year remains subject to the legal season.
