No gauge on this water — readings are regional estimates from weather, not a live gauge.

Moderate freshness· 12 mm in 48h

Moderate rainfall (12mm) may bring some water movement. Watch for fish moving to new lies as water rises slightly.

Head to
Wind driftS wind
Northern end

A southerly has held for 8 hours, running warmer than the water (14°C air against 11°C water). Expect fish at the northern end — the bank it is blowing into — where the drift piles food, colour and warmth together. This reads the upper water, though — a bottom bait at range feels it far less than a floater or a fish in the margins. 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
Where
Work Muddler Minnow on the bob and Perch Fry on the point.
The plan
Plan A

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 — at anchor

Windy conditions suit anchoring in productive areas rather than open-water drifting.

About this water

A cluster of small mixed fishery lakes around Pettigo — Bannus, Drumgun, Aveghy and part of the pilgrimage Lough Derg — together with the Leaghany and Derg rivers, all managed by Pettigo & District Angling Association. There is a good stock of native brown trout, three-quarters of a pound to a pound and a half and bigger in Aveghy, sharing the water with roach, perch, bream and pike. This is the Foyle region, fly-only, with a bag limit of four; club boats only, to keep the zebra mussel from spreading.

Hatches & food

A cluster of mixed limestone-drumlin lakes with reasonable but not rich fly life — duckfly and buzzer early, lake olive and a light mayfly on the better lakes, then a strong summer sedge for the native trout.
