A sprawling complex of interconnected lakes, islands, and drowned drumlins in the upper Erne system — more wetland maze than single lough. Shallow, weedy, and tangled with reed beds and lily pads: perfect ambush territory for pike. Oughter is one of Ireland's classic pike-on-fly destinations, with fish stalked visually in the shallows and cast to from drifting boats. The labyrinthine channels between islands concentrate pike on predictable patrol routes. Big pike to 20lb+ are taken every season.
