Head to
Wind driftW wind
Eastern end

A westerly has held for 7 hours at much the same temperature as the 14°C water. No thermal steer either way, but the drift still stacks food against the eastern end — the bank it is blowing into — so start there. 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
Start with Perch Fry (8-10_long_shank) — on the point. If that does not produce, switch depth or speed before changing the pattern entirely.
The plan
Plan A

Start with Perch Fry (8-10_long_shank) — on the point. If that does not produce, switch depth or speed before changing the pattern entirely.

Plan B

If the daddy is being refused, drop to a hopper or a single foam beetle and cover rising fish individually.

Watch for

Daddy Longlegs may strengthen through the middle of the day as conditions warm.

Either bank or boat

Good ripple suits both bank and boat. Bank: work inflows, dam walls, and points. Boat: broadside drift covering wind lanes.

About this water

A 578-acre ESB hydro lake at Ballyshannon, closed for salmon and sea trout. The brown trout here are few but they grow large — fish to seven pounds — and the time to look for them is the mayfly, working the old river course at Edenagor and the shallows along the north shore. There is also a strong and under-fished coarse fishery here: big bream, roach, and pike to forty-six pounds. Shore fishing on the north shore only; keep the boat well clear of the hydro stations.

Hatches & food

A large limestone-influenced ESB hydro lake whose richest fishing is the mayfly (Ephemera danica) around the old river course in late May; otherwise duckfly, lake olive, sedge and buzzer feed the low-density big browns.
