Duncrun is woodland fly water in County Londonderry, the sort of place that settles in well once you've fished it a couple of times and learned where the fish like to sit. The lakes lie over volcanic ground, sheltered by trees, which takes the sting out of a brisk day and gives you somewhere to fish when the wind is up. It rewards a fly-focused approach — buzzers worked slowly through the cool water, a diawl bach team as spring warms along, a damsel pulled past the weed in summer. On a soft grey day with a touch of ripple the rainbows feed with confidence; on a hard bright one they drop away and you fish deeper and slower for them. Honest sport in a quiet corner that gets better the more you understand it.
