Midlands limestone trout lake with a long history of holding specimen brown trout — fish here are fighters. Once compromised by pollution, the recovery has been remarkable. Mayfly hatches from mid-May are productive. The lake fishes particularly well from late April through June when olives and mayfly dominate. Excellent boat fishing when the breeze is right.
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.
